exec() not saving output

[Shawazi]

I have an exec line for imagemagick to see if an image is RGB

exec('identify -verbose '.$file, $exec);
var_dump($exec);

spits out:

array(0) { } 

However if I run the command in shell, it runs and spits out quite a bit of information. This has worked before and now I'm wondering if there's some server setting that got changed to make it fail.

Maybe try shell_exec() and see if there is any error output? (It could be that the web user under which you script runs does not have the necessary path or other environment settings to runn the command?)

$result = shell_exec(<your command here>);
var_dump($result);
