php is one of the site programming languages developed for web design, which stands for Hypertext Preprocessor.
About 75% of the world’s websites use this type of language for the backend of their website.
The most famous examples of it in Iran are Digikala and abroad Facebook and Yahoo.
This language was created by Rasmus Lordov in 1373, which is currently being developed by the PHP group.
This site programming language can be integrated with HTML. php is actually a free and open source scripting language; which runs on the server.
That is, when the server receives the user’s request, it processes it through a scripting language on the server side and performs different operations based on that request and finally provides the user with a dynamic page.
So that the user’s browser receives the response containing the page codes from the server, which uses its own rendering engine to present the page to the user in a readable manner.
PHP is preferred for web design because it is free and is used by web designers all over the world.
The PHP group provides a complete source code that allows users to customize and develop web designs as needed.
php works easily with any operating system including Lennox, Mac, OSX and Linux.
PHP also supports many web servers in use, including Apache and IIS.
As we said, the PHP programming language is on the server side, it does not need to be installed and requires less processor space.
Well, this means that it does not affect the speed of your system.
PHP’s flexibility, scalability, and usability in a user-friendly design have made it one of the most versatile languages for creating web pages.
One of the other advantages of PHP is that it is very easy to use at any skill level; Whether you are a newcomer or a professional programmer, you can use it effectively.
PHP dynamic content for web servers allows users to use the back end programming language Site focus.
PHP users are not limited to HTML output, they can easily output any text such as XHTMLOr use another XML file format.
PHP users are also able to attach other types of images such as PDF files and Flash videos;This can be generated and stored automatically in a system instead of needing to be printed, creating a server-side repository for dynamic user content.
