"php -m" - Display Loaded Modules
This section provides a tutorial example on how to get a list of all loaded modules from the PHP runtime environment using the 'php -m' command or the get_loaded_extensions() function.
To get a list of all loaded modules, you can run the "php -m" command:
herong$ php -m [PHP Modules] calendar Core ctype date exif fileinfo filter ftp gettext hash iconv json libxml openssl pcntl pcre PDO Phar posix readline Reflection session shmop sockets sodium SPL standard sysvmsg sysvsem sysvshm tokenizer Zend OPcache zlib [Zend Modules] Zend OPcache
If you are running PHP scripts on a Web server, you can call the get_loaded_extensions() function in a script to get all loaded modules (extensions) in an array.
First write a simple script as shown below:
<?php
# get-loaded-extensions.php
# Copyright 2009-2026 (c) HerongYang.com. All Rights Reserved.
print("<pre>\n");
$list = get_loaded_extensions();
var_dump($list);
print("</pre>\n");
?>
Upload the script to your Web server:
Then run the script using its URL (e.g. http://server.name/get-loaded-extensions.php) in a browser. You will see the same information as the "php -m" command.
