Sometimes you can find information that the site is created using PHP, but many people do not imagine what it is. PHP is a universal scripting language oriented on web development. Let's look at what it can be done on the site.

We have already told that such technologies are used to develop sites:

PHP is another programming language, but it refers to the server. This means that the code written on it is running on the server, that is, on the computer where the folder is located. And it is performed even before the page is loaded into the browser. The visitor, in essence, sees the result of the work of the PHP script.

The code itself can be written as a program in a separate file and connect to the page or call the link. Or can it be inserted into the HTML code in the tags And run in the process of reading the markup server.

You may ask - for what you need another programming language on the site, if you already have JavaScript? The point here is in different fields of application.

Scripts written in JavaScript are performed in the browser when the page is fully loaded. With their help, you can make beautiful effects on the site, add different dynamic elements, such as sliders or drop-down menus. At the same time, the page remains static, and all visitors see it equally.

Another thing is a PHP page. Inserts of the code in this language can generate some of its parts on the server, and for different visitors, one and the same page may look different. For example, depending on the region, the range of goods in the online store will differ, or the text will be displayed in the language of the visitor, if it is from another country.

But this is not all that PHP is used on sites.

In PHP languages, almost all CMS are written through which it is convenient to manage the site, configure many of its characteristics - from the appearance to the output content. It can also interact with the database through additional modules, record information or read in it, perform any requests.

With PHP you can implement such things:

In general, the use of PHP allows you to realize many interesting and useful things impossible on the static site. This language is very popular and supported by all hosting. Therefore, it can be free to use on its sites to get the desired functionality.
