Ever needed to make a quick adjustment to the php.ini file but you weren’t sure where it was? Here’s a quick command you can use:

php -i | grep php.ini

What this does is tell the php command-line application to run a phpinfo() and output it in text format to the shell. Then filtering it through grep to find the actual line, which will display like so:

Configuration File (php.ini) Path => /etc/php.ini

You can, of course, always put a new php file in your web server root directory and add in the following:

<?php phpinfo(); ?>

And then browse to it in your browser.
