Lately, we have heard of many terms that have been very popular with bright minds - and here I mean what I say - because that subject area requires patience, skill and creativity, namely "programming", and in particular the PHP programming language.
Perhaps some of us realize that programming is considered absent from the present in that hypothetical world surrounding us today, and you may be among the millions who intend to learn programming languages that have contributed greatly to the development of the world in which we live now, and you surely wondered how the applications that we have been talking about were programmed day and night And how it was done with such perfection as Facebook and others, and in the utmost simplicity it is the PHP programming language as mentioned previously.
What is PHP?
The PHP language in the beginning was called (PHP / FI) and it was, in fact, not a programming language, but rather a group of applications written using the Perl language, and today it is considered a scripting language on the server side, and this means that it was used to build interactive websites and web applications , In a safe, effective, inexpensive, and finally reliable way.
Who founded it : -
The php language was founded by the programmer Rasmus Lerdorf in 1994 in order to develop and program websites, and it can also be used in creating programs that have no relationship to the web. And it was developed by Andy Gutmans , Ziv Soraski later re-issued the original version, and released the version, which was called " PHP3 " at the time .
The meaning of the abbreviation (PHP) : -
It is an abbreviation for (Hypertext PreProcessor) and this is the most popular abbreviation, and this is a reverse arrangement of letters. In general, the alternative explanation is that the initials come from the old version called (Personal Home Page) and at least it is the correct arrangement of PHP.
The popularity and spread of the PHP language : -
By entering the world of software, we cannot limit it to a specific word, for example, not to collect, we are standing in front of a term that is difficult to measure in quantity and quality, such as the Internet, for example, but the PHP language has influence and authority in front of all this, so what is the reason behind that?
- It is robust and resilient enough to be the heart and template of the largest web notation system ( wordpress ).
- It has enough magnitude to qualify it as the source of the operation of the largest social network such as Facebook.
- It is large and spacious enough to be the largest knowledge encyclopedia such as Wikipedia.
In this way, we can see the extent of its strength and control in its field, as PHP recorded tremendous development and growth by acquiring 80% of the total sites in the world.
PHP is the parent : -
After we got acquainted with that language ostensibly, let us get to know it in some detail: -
We said earlier that it is considered “server-side scripting” What is meant by that sentence: -
This means that it cannot be implemented on your personal computer known as (the client), but on the device from which you requested the page, which is known as the (server), which is used to display web pages naturally and dynamically, and then the results are delivered to you and displayed on your browser.
To illustrate, we take this example: -
When you want to log in to a site, it will ask you for the e-mail and password after completing the previous two fields on the server of the site prepared in advance using the PHP language, the data is sent to your own device. Main server.
And this is unlike (Java Script) , the source code written using PHP is not seen by the user at all, and this means "that the browser does not understand it."
Features of PHP language

Defects
- It is not designed to create massive applications.
- Safety .
A summary of the above
PHP language is one of the most popular programming languages that is used in creating websites and it is one of the languages that the web server interprets and executes its code and then sends the result to be displayed in the user's browser, and PHP language is used to create dynamic web pages i.e. pages with variable content And this content changes as a result of interaction with the user.
