Question

I want to convert a pdf file to an image with PHP, but i can’t get the command worked. PHP returns a 4. I don’t have any kind of idea what that can be.

I am using the next code:

$tmp = system("convert -version", $value); 
var_dump($value);

Someone an idea?

try

  exec("convert -version 2>&1", $out, $ret);
  print_r($out);
