For a better understanding of this example, we always recommend you to learn the basic topics of PHP programming listed below:
PHP (recursive acronym for PHP: Hypertext Preprocessor) is a widely-used open source general-purpose scripting language that is especially suited for web development and can be embedded into HTML.
The below mentioned program is the basic program to get the current state of PHP. For this, we use the in-built function called
phpinfo() - Outputs information about the current state of PHP which includes information about the PHP compilation options and extensions, PHP version, server information, and environment, PHP environment, OS version information paths, master and local values of configuration options, HTTP headers, and the PHP License.
Because every system is set up differently,
phpinfo() is commonly used to check configuration settings and for available predefined variables on a given system.
phpinfo() is also a valuable debugging tool as it contains all EGPCS (Environment, GET, POST, Cookie, Server) data.
STEP 1: Use the phpinfo() to display the Version and Configuration details.
<?php phpinfo(); ?>
