使用exec（）从PHP运行PhantomJS

Question

I've got the following script:

#!/bin/sh
export DISPLAY=:0
phantomjs --version

It try to run it from the following PHP script:

<?php
$result = shell_exec('sh test.sh'); 
echo $result;
?>

This script return the following error:

[Thu Jun 19 10:31:31 2014] [error] [client] test.sh: line 3: phantomjs: command not found

I tried to run phantomjs -v by hand in a console, and it runs fine. I checked the PATH, and phantomjs is correctly defined and found.

The execution environment is a virtual Server with LiveConfig. Can someone help me understand what I'm doing wrong ?

Answer 1

Your PATH probably lacks the location for the phantomjs executable. PhantomJS is probably installed in /usr/local/bin so you need to add this to your PATH variable:

#!/bin/sh
export DISPLAY=:0
PATH=$PATH:/usr/local/bin
phantomjs --version

To check what the current PATH is, you could begin the shell script with:

#!/bin/sh
echo $PATH
