I have installed PHP v7.2. when I do php -v in my terminal, I get:

$ php -v
PHP 7.2.0-2+ubuntu16.04.1+deb.sury.org+2 (cli) (built: Dec  7 2017 20:14:31) ( NTS )
Copyright (c) 1997-2017 The PHP Group
Zend Engine v3.2.0, Copyright (c) 1998-2017 Zend Technologies
    with Zend OPcache v7.2.0-2+ubuntu16.04.1+deb.sury.org+2, Copyright (c) 1999-2017, by Zend Technologies

Which php, gives me, /usr/bin/php?

But there is no php.ini in that directory. How can I find the location of php.ini?

  • locate php.ini will search for it. Though you also will need to update it with updatedb once after installing (the database is not realtime to speed searching up by a lot).

  • $ updatedb updatedb: can not open a temporary file for `/var/lib/mlocate/mlocate.db' Jan 3, 2018 at 10:31
  • You need sudo.

You cand find the php.ini file in the following directories:

  • /etc/php/7.0/apache2/php.ini
  • /etc/php/7.0/cli/php.ini

Hope it helps.

  • Where 7.0 is the version of PHP. You could include these commands with a little explanation, also the Rinzwind's comment, in your answer to make it complete. :-)

  • This is for the apache installation. This is differnet from what you get by running php in the terminal Jan 3, 2018 at 10:32
  • In that case, execute in your terminal sudo updatedb and then execute locate php.ini this will show the location of all php.ini files in your system.

  • @RamasamyViswanathan - look at the second bullet - cli means command-line-interface.

You can also make a file that calls the phpinfo() function. Simply add the following code into a file such as phpinfo.php in your webroot, and access it via the webserver.
