Easy PHP Programming

Website development needs to incorporate a suitable Programming Language like PHP for the excellent boost that it gives to performance. PHP is one of the most useful scripting languages regularly used in top operating systems like Linux, UNIX and Windows. PHP gives the multiple benefits of object oriented programming (OOPs), command line interface and desktop applications – some of the essential features that website developers look for in a scripting language. Website development also needs to widen the choice of programmers as much as possible. Here also PHP scores a point as the most compatible language for an array of databases such as Oracle, SQL, My SQL and ODBC. It is also available for embedding HTML coding which fulfills the requirements of dynamic website development. PHP has become an essential tool for most developers and designers who prefer it chiefly because of its flexibility and usefulness.

Another important feature of PHP is that it is suitable for big ventures like customizing CRM solutions, community sites, chatting forums and E-Commerce portals. No other programming language seems as affordable and easily controllable as PHP when it comes to ambitious website development with a well defined business goal.

To enlist a few uses of PHP that are integral parts of web development, we have to mention the following- creation of HTML web forms, compatibility with databases, monitoring of sessions and cookies to track visitors to a site, provision for up-to-date file management , creation of XML for E-Commerce sites

There are some points to be noted while using PHP as a programming language-

o PHP gives the fullest opportunity to monitor a website including access to files, password and Ethernet connections. It makes the idea of participatory business model successful in the web arena.
o HTML can be displayed through this system with the option of editing web form that may seem to be essential in course of time.
o PHP gives swift access to database through an inbuilt checking system and provides essential link.

Use of PHP ensures security for content and application which are monitored by the server rather than any other system. This also places the procurement of contents and applications on the fast track and minimizes difficulties faced by the users due to browser problems.

Website development is a fine tuned process where the recommended features of a website have to be incorporated as accurately as possible. PHP expands the horizons for programmers and developers and helps them build websites according to demand.

PHP is an acronym for Personal Home Page or Hyper Text Pre-processor. So from this you can understand that, this is some thing to do with web development. Yes, you’re right! PHP is a scripting language and usually embedded with the HTML (Hyper Text Mark-up Language).
 
PHP was developed by The PHP group and was designed by Rasmus Lerdorf in the year 1995; PHP2.0 was released in the year 1997. A PHP file usually has .php extensions. Rasmus Lerdorf designed PHP to handle usage logging and to create server side forms, later he developed it for large web based projects.
 
PHP was mainly designed in order to provide the dynamic web pages and it mainly focuses on the server side scripting. When the PHP code is given as an input to the web server it gives HTML content as the output.
 
PHP runs almost on any web servers and it is free software. It is also easy to implement and use, the code is in the human readable form. These make an advantage to PHP. This scripting language not just focuses on server side scripting but also executes the scripts and is used to generate the graphic user interface (GUI) on client side.PHP is an ideal tool for search engines. PHP with MySQL can be used to access any type of data. Since the PHP has quite a number of extensions it helps in easy data interaction.
 
Some of the main advantages of PHP are such as; it can be operated in cross platforms, it can run on almost all the servers, rich text processing, and compatible with large number of database. PHP is easy to use; you just need to know the basics of programming and knowledge on C language.

What is PHP?
PHP is short form of Hypertext Preprocessor, which is a widely used, server-side web programming language that was originally designed for web development to produce dynamic web pages.

Advantages of PHP
PHP gained a lot of popularity for more than a decade because there are many benefits to go with PHP scripting language.

Firstly, the main advantage of PHP is the ability to interact with MySQL database. MySQL is popular for web applications like Wikipedia and PHP-Nuke and acts as the database component of LAMP (Linux, Apache, MySQL and PHP) system. PHP is able to interface with it very well. MySQL is used with PHP as back-end tool. Therefore, PHP and MySQL are fantabulous choice for webmasters who are going to automate their web sites.

Secondly, PHP is open source and similarly to most open source software, it is free for both personal and commercial use. In addition to the nature of free of charge, as PHP is a open source language and there are a huge community of open source applications work on it to fix up bugs and other issues. And therefore, when talking about the issue of security, it is much safe when compares with other language. And also various security levels which can be set in the.ini file to defend the system from attacks of users.

Thirdly, PHP is easy to use and runs really fast. Even though you are an inexperienced web developer, you can learn the basics of PHP development and start your development in a very short period of time. PHP is very simple. Even HTML coders can integrate PHP programming straight into their pages. Also, if you are an experienced programmer, you can utilize some of the more advanced features of PHP to maximum your potential. When developing a website, it is really necessary to make sure that visitors will be able to load your website as quickly as possible. With PHP programming, your website will load quickly because there is Apache module normally written in C.

What is PHP web hosting?
As the name suggested, PHP web hosting refers to a type of web hosting service that provide support for PHP programming language. Since there are so many benefits of using PHP programming language, to make sure that you will be allowed to use PHP on your website, you will need to make sure that your web hosting company will offer its customer with the popular feature. Most of the best web hosting companies offer PHP hosting solution as there is a lot of demand for it. When registering a hosting service, it is also necessary to make sure that you will be provided with the latest version of the PHP script. Because with the rapid growth and development, newer version has regularly appearing and each time a new version comes, there might security loophole if you are still using the outdated version.

PHP Web Hosting Cheap and Affordable
When search over the internet for web hosting services, you will find that PHP hosting is much more affordable compared with other type of web hosting solution. The main reason is because PHP, as an open source language, is free. And it usually comes along with the popular database, MySQL, which is also free. Since these technologies are available for the provider to get for free so they will of course lower the hosting fees to their customers.

How to Find Ideal PHP Web Hosting
When you are going to find an ideal PHP web hosting service to build your website for your small business then you need to know the three basic things of web hosting: First, ensure that the service has enough bandwidth to meet your website requirement. Second, there should be enough disk space available for not just your current needs, but also your future development. And third the hosting package should also provide you with sufficient databases for your web site requirements.

Overview:

When creating a website, it is often necessary to display dynamic text on the page. This text will change every time the page is loaded.

To create this solution, a database could be used. There is however another solution, it uses PHP’s built in rand() function and an array().

PHP Functions

PHP has hundreds of functions to make programming easier and more efficient. A PHP function is a built in piece of code that when called, performs a specific ‘function’, or routine, and then returns the result.

For example, the strlen() function takes in a string (a series of characters), and returns the length or how many characters that string contained. Here is how it works:




The Output would be ’24′, because there are 24 characters in that string (include the white space character).


Rand() Function

PHP has a built in function that will generate a random number between a range. To use it, put a starting number in the first parameter location, and the end number in the second parameter location. This will create a range.

For Example:


rand(1,3);


This would generate one number each time, and it could be either 1, 2 or 3.

PHP Array

When using PHP, an array can be used to store any kind of data (strings, numbers, objects, arrays, booleans). We will use an array to store text (a string).

Arrays store information using a KEY – VALUE notation. The Key is the location of our stored text in the array. The Value is the actual text we plan to store. Here is how it looks.


$myStorageArray[KEY] = VALUE;


The KEY is a whole number, like a 1, 200, or 342. The VALUE is a string (a string is a series of characters wrapped inside single or double quotes). So the correct usage would look like this:


$myStorageArray[1] = ‘I am six feet tall’;
$myStorageArray[2] = ‘My hair color is brown’;


Do you see how it works. Put a unique number in the KEY, and set it’s VALUE to whatever text you want to store. The key is the location, and we will use it later to pull the data (VALUE) back out to print it to the screen.

Random Text Generator

Putting it all together, we will use rand() and array(). Rand() will generate a dynamic number and the array will store our data that we will retrieve dynamically.

Our task is then a simple matter of using the random number as a KEY to see the VALUE of the array. Here is the full code.

The $myQuotes array stores 3 of my favorite ‘modified’ quotes. The $randomNumber variable will contain a 0, 1, 2, and is used as a $randomNumber variable and placed in the KEY of the $myQuotes array. To make sure this will work, choose consecutive numbers – 1,2,3 or 4001, 4002, 4003, etc.

Every time the page is loaded, the echo statement sends one of the 3 quotes to the screen.

Conclusion

Using only simple PHP tools, you are able to quickly create a dynamic text generator using only rand(), echo, and an array. A simple, but very powerful PHP trick. The array can have as many KEY-VALUES as you want, just remember to increase the size of the random number range to see all of your values.

PHP programming has become a powerful programming technique for business websites and the demand for dedicated PHP programmers is ever increasing. On the other hand, economic crunch has forced companies to resort to cost effective means of doing business. As a result, they may end up hiring PHP programmers who charge less. Industry experts opine that such people do not hold promise of quality and timely service. In order to bridge the gaps created by hiring an able programming person in cost effective ways, staff augmentation services can be used.

Of late, Staff augmentation service providers are coming up with various modules to satisfy the growing demand for skilled IT staff like web developers and PHP programmers by sourcing them in flexible ways. The companies in need of these programmers can either outsource the entire project to the servicing company or hire a PHP programmer to work for them till the completion of a specific project.

The competence of the person who writes a PHP code counts most in the successful execution of a project. When you hire a PHP programmer through staff augmentation services, you can rest assured that you will get a good output since the service providers take responsibility of outsourcing a skilled programmer to execute jobs requiring PHP coding.

By doing this, you can make a great save on the overhead charges of staffing a programmer permanently in your company and the money you would save by hiring a PHP programmer through a Staff augmentation service provider is the icing on the cake.

It is always highly in demand and as the internet continues to progress, it is likely that more and more people will need PHP work done for their websites and other projects.

Hyper text preprocessor (PHP) and Active-server-pages (ASP) are the two standard programming languages for website application development and more significantly when it comes to produce database-driven websites to interrelating hugely with databases. PHP is an open-source programming language which is derived from lots of different languages. On the other hand ASP is such kind of programming languages which preferring Microsoft product mostly.

Both programming languages PHP and ASP are used to develop dynamic database oriented websites. Active Server Pages (ASP) is normally from Microsoft and is used only with Internet Information Server (I.I.S.) that runs on Microsoft Servers also. But on the other hand you can say PHP is platform independent programming languages and can connect with several kinds of databases.

There are a lot of differences between ASP and PHP.

Expenditure

To run ASP.net programs first need to install I.I.S. on a Windows server platform, this is not a free package. PHP programs can run on Linux, which is free package. Even the database connectivity is expensive for ASP, because it require ms-S.Q.L product of Microsoft that needs to be acquired. Same time on the other hand PHP generally uses My-S.Q.L for database connectivity, which is freely accessible.

The Simplicity in Coding

PHP codes itself are very light in weight, a contract programmer who begins his career into PHP, does not felt any pressure to look the source code to understand. Whereas In ASP codes are not so easy to quick understand.

Database Compatibility

PHP generally being extremely flexible as it uses My-S.Q.L for database connectivity, which is freely accessible. Same time on the other hand Database compatibility is expensive for ASP, because it require MS-S.Q.L product of Microsoft that needs to be acquired.

General Run Time

If we evaluate the running speed of PHP and ASP then PHP should gets the upper hand. Normally it is viewed that PHP code runs quicker than ASP code. Due to COM based architecture, ASP uses server space to run while PHP code runs on its own inbuilt memory space.

Background Language Support

ASP has a similar like Visual Basic type of syntax that also linked to Microsoft products as well. On the other hand PHP codes are based on generally C++ language and the syntax, which is used in PHP, is quite similar to C/C++ syntax. C/C++ is still considered by maximum software programmer is the finest programming language and people who love C++ language would certainly feel more relaxed with the PHP syntax.

Running Platform Connectivity

PHP codes can run on different platforms like UNIX, Linux, and Windows whereas ASP codes are mostly linked with Windows platforms. Though, ASP programs can run on a Linux platform with the help of ASP-Apache installed on the server.

Further Tools Cost

Several tools used in PHP are mostly free of cost in the market and as PHP is open source a lot of codes can be available in open source forums and blogs. PHP has inbuilt attributes like ftp, encryption methods, even email also from a web page but in ASP such attributes are not obtainable and for this reason only some more features are required which are not free that increase the total cost as well.

Larger Applications Support

PHP is just as protected as ASP from coding level. The main difference is only for private data like “social security numbers”; “PIN numbers” etc. ASP is more practicable option. Organizations like government firms normally don’t have much stipulated commercial budgets and looking for required security, they really helpful ASP.net.

At the end, we can make a conclusion that both programming languages have their advantages and disadvantages specific to user requirement. It can be said that both the programming languages have their own significance depending upon the users requirements and budgets. It is viewed that in any discussion board, ASP.net is similarly capable but many of them suggesting PHP for small business owners those who have a fixed budget and does not required superb security support. PHP cannot provide e-commerce application development, only for them ASP.net will be the best choice.

Believe it or not, but there is PHP programming code that will not work on every installation. This is often a big problem for the developer. Code that is working correctly on the developers computer, and on the web server, may not work on other web servers.

The start and end tags are the culprit. The following tags are most widely used when developing code. These are available with a default installation of PHP.

Line 1:

Line 1 is the start tag. It tells the PHP interpreter to start processing the program. Line 2, is the end tag, it tells the interpreter to stop processing the program. There are 2 other tags to be aware of. These are not enabled by default. They require you to change the settings in the php.ini file

Note: php.ini is a text file that holds the configuration settings for the PHP engine. Once these are changed, the web server must be restarted for the changes to be accepted.

Short Tags:


These are enabled with the ‘short_open_tag’ directive found in the php.ini file.

ASP Tags:


These are enabled with the ‘asp_tags’ directive found in the php.ini file.

Why would you choose one of the over?

A good developer is always looking for ways to save time. One tactic is to write less code. Beginners do not always know how to write less, like the more advanced developers. Advanced developers use shortcuts wherever they can.

One thing they do to reduce the amount of words in the program by typing:



Even though it is only three characters less (p-h-p). Not typing 3 characters adds up over time.

This is not a good idea. In the short term it may work. But a good developer must always be thinking about the future. How will the code grow, where will it end up.

As a website matures, so does the programming code. As a site gets larger, it is ofter moved to a new web server. The problem is that all web servers are not setup the same way. If short tags are enabled in the beginning. They may not be enabled on the next web server. Do you see the problem.

Bottom Line: Use the universally accepted PHP tags to ensure the success of your web programming project

If you want to be considered an effective and avid PHP programmer, then there are some topics in the language that you should without a doubt know. One of the biggest, most important topics in PHP is dealing with database connections, especially ones with the MySQL database platform.

If you know how to work with a MySQL database in PHP, then you can make just about any website with dynamic content. You will be able to handle user registration, commenting, blog posts, and more. The very first thing you should learn when dealing with databases is how to connect. The following PHP code is how you connect to a MySQL database:

$host = “localhost”;
$username = “db_username”;
$password = “db_password”;
$database = “db_name”;
$dbc = mysql_connect($host, $username, $password);
mysql_select_db($db_name, $dbc);

You may be sitting there wondering what this code does. If you have programmed in PHP before, then you know that $host, $username, $password, and $database are all variables. Each of these corresponds to what the variable is called. For example, $host is the host that the database is located on (99% of the time it will be localhost), $username is the username to access the database, $password is the password associated with the username, and $database is the name of the database we are connecting to.

The next two lines are PHP functions. The first function, mysql_connect, makes a connection to MySQL on your host. It returns a link identifier in case you are working with multiple connections. The parameters it takes are the database host, the username, and password. The next function, mysql_select_db, selects the database we will be using. The two parameters are the database name and the link identifier (link identifier is optional, but good practice).

Using these lines of code is how you make basic access to a database. Once you do this, you can do many things like retrieve data and add data using the mysql_query function. This function also takes in two parameters, a query string and the link identifier. A good example of using the mysql_query function is:

$query = “INSERT INTO table (column1, column2,…) VALUES (‘data1′, ‘data2′,…)”;
$result = mysql_query($query, $dbc);

Obviously this code will not work with the ellipsis; this is just to show you can have as many columns in there. These two lines of code will insert data into the database. The first line assigns a query to the $query variable. The second line runs the query with the associated link identifier (optional).

Once you master these three functions, you are well on your way to becoming an expert at PHP programming with databases. There are many other functions that you should learn that work well with databases, but these 3 are a good start.
