How to run php code in gedit using External Tools plugin?

Question

I've tried this code in External Tools with actual document as input. But it doesn't work.

#!/bin/sh
/usr/bin/php -r

Syntax check works as expected

#!/bin/sh
/usr/bin/php -l

Outputs either error message or "No syntax errors detected"

Answer 1

For the external tools, set the "Input" to "Current document" and the command is just php (no options):

php

The output in the bottom pane will be the output of your script. Just keep in mind that this is only going to work for local files.
