How to check the php.ini file path?

Create a new test.php file with the following content:

<?php
phpinfo();
?>

Then use the url to access test.php in the browser, and a large amount of relevant information such as php-related configurations and plug-ins will be displayed. Among them, the Loaded Configuration File item can find all effective php.ini file paths.

Or, more simply, you can directly run the command to output the above information (if you have installed multiple versions of php, be careful to use the correct php command):

php -r "phpinfo();"

Run a php file locally

php [-f] test.php
