Where is the php.ini file on a Linux/CentOS PC?

On a CentOS system, the php.ini file is usually located in the /etc directory. To find the location of the php.ini file on your system, you can use the phpinfo() function in a PHP script.

Here is an example of how you can use phpinfo() to find the location of the php.ini file:

<?php

phpinfo();

?>

Save this script as "info.php" and place it in your web server's document root (e.g. /var/www/html). Then, access the script in your web browser by visiting http://your-server-name/info.php.

This will display a lot of information about your PHP installation, including the path to the php.ini file. Look for the "Loaded Configuration File" row in the output to find the path to the php.ini file on your system.
