Where can I find php.ini?

On the command line execute:

php --ini

You will get something like:

Configuration File (php.ini) Path: /etc/php5/cli
Loaded Configuration File:         /etc/php5/cli/php.ini
Scan for additional .ini files in: /etc/php5/cli/conf.d
Additional .ini files parsed:      /etc/php5/cli/conf.d/curl.ini,

That’s from my local dev-machine. However, the second line is the interesting one. If there is nothing mentioned, have a look at the first one. That is the path, where PHP looks for the php.ini file.

You can grep the same information using phpinfo() in a script and call it with a browser. It’s mentioned in the first block of the output. php -i does the same for the command line, but it’s quite uncomfortable.
