I'm receiving the following error from my crontab and have a pretty good idea what is causing it; I just don't know what to do about it.
/bin/sh: php: command not found
The entry in crontab file
*/10 * * * * php /path/to/external.php
Now my assumption is that it cannot find the php location and is defaulting to /bin/sh. How do I locate my PHP install directory? After I find it I assume I just modify the section of code above where php is?
