Used of PHP in web applications
PHP is one of the most popular languages used on the world wide web for server side scripting. What server side scripting means is that the scripting language interprets information which is on the server – the computer which contains all of the data for the web site and which sends the web page information to the users who want to view it. A PHP script will determine how the server interprets information and how it will be presented as a web page – giving you the ability to design a site which will read data from files on the server and display it for visitors in whatever manner and format you want.
What kind of data can you present using PHP, and what kind of applications does the PHP scripting language have? One of the most popular kinds of online application which uses the PHP scripting language is the online forum – there are thousands and thousands of online forums on the world wide web which discuss all types of subjects. The most popular forum software is written in PHP and provides users with the ability to create their own new accounts, search through the archives of the forum, put up new content on the forum through posts and edit their earlier posts. PHP forums also give you a lot of abilities to moderate the way that the forum is designed and run – you can create whatever sections and subsections you like, promote or demote users of the forum to be moderators or just standard users, ban users who do not go along with the rules of the community, set up technical access details, and so on.
PHP is also a very popular scripting language for developing front ends to databases – with a system of PHP pages you can enter information into a standard web database, such as a Mysql database, search through the entries in the database and portray the contents of the database through pages which give the user background on the data, links to related data, and options on how they can edit or leave comments and additions. Mysql is the most popular of the online database systems and it is fully compatible with PHP, so you can be sure that if you know PHP and you have a Mysql database you can create a front end which will help people use their data more effectively.
Finally, PHP is simply used to create a wide variety of standard web pages, in situations where there is some kind of multi-user post editing software or where a special system is used to organize the data which is uploaded to a new site or community site. An entire site can be designed in PHP so that it is easy to change the appearance and layout of the site whenever you want without making alterations to large numbers of HTML files – all that you need to do is change the layout information in the PHP and you are good to go! PHP makes all of these tasks easy, and you can enjoy all kinds of applications for your PHP know-how!
