An addition to my previous post (you can replace it)

If your php script doesn't run with shebang (#!/usr/bin/php),

and it issues the beautifull and informative error message:

"Command not found." just dos2unix yourscript.php

et voila.

If you still get the "Command not found."

Just try to run it as ./myscript.php , with the "./"

if it works - it means your current directory is not in the executable search path.

If your php script doesn't run with shebang (#/usr/bin/php),

and it issues the beautifull and informative message:

"Invalid null command." it's probably because the "!" is missing in the the shebang line (like what's above) or something else in that area.
