How to Locate php.ini and List Enabled PHP Extensions
This article explains two methods to locate the php.ini file and view installed PHP extensions—using a simple PHP script with phpinfo() and the command‑line tools php -m and php --ini—while also promoting a PHP online training class with enrollment details.
Purpose : Show how to check which PHP extensions are enabled and locate the php.ini configuration file.
Simple method : Create a directory with an index.php containing <?php echo phpinfo(); ?>, start a built‑in server with php -S localhost:2233, and open http://localhost:2233 in a browser to view the configuration.
Recommended method : Use the command php -m to list all loaded modules quickly.
Example output includes modules such as bcmath, curl, date, etc.
Finding the php.ini path : Run php --ini which prints the configuration file path, the loaded php.ini file, and directories for additional .ini files.
Typical output shows Configuration File (php.ini) Path: /usr/local/etc/php/8.1 and Loaded Configuration File: /usr/local/etc/php/8.1/php.ini.
