How do you determine the path to php on a server?

[Trisha]

I need to find the path to php5 at my host.

At least I think I do. When using a command line to run a php script I get a message like:

If you are sure you already have php5 installed, it may be installed in a different path from php4.

I figure I need to try something like:

path/to/php5 update.php

Based on information I can get from 'phpinfo();' - where would I find the path to use in a command like above?

Try this command in shell:

which php
