PHP, which stands for “Hypertext Preprocessor,” is a widely used, open source scripting language used for developing web applications. PHP code can be embedded into HTML code, or it can be used in combination with various web template systems, web content management systems, and web frameworks.

PHP code is executed on the server, and the resulting output is returned to the client’s web browser.
PHP has a wide range of features, including:
- Support for a wide variety of databases (MySQL, Oracle, DB2, etc.).
- Increased security compared to other scripting languages.
- Syntax that is easy to learn for new programmers.
