"PHP: Hypertext Preprocessor" is an acronym for "PHP: Hypertext Preprocessor." PHP is an open source scripting language that is frequently used. On the server, PHP scripts are run.
PHP is an HTML-enabled server-side programming language. It's used to manage dynamic content, databases, and session monitoring, as well as to create full e-commerce websites. MySQL, PostgreSQL, Oracle, Sybase, Informix, and Microsoft SQL Server are just a few of the databases it supports.
A scripting language, sometimes known as a scripting language, is a computer language that allows scripts to be written. Because we can integrate php code into HTML, PHP is a scripting language. If the code of a programming language can be embedded or integrated with another language or script, it is referred to as scipting language.
If the web server detects that the request is for a PHP file (usually index. php), it will send that file to the PHP interpreter for processing. The PHP interpreter will read the PHP file, parse it (along with any additional files present), and then run it. The PHP interpreter will return an output once it has completed running the PHP file.
