Environment: Using brew installed ghostscript and brew installed imagemagick on Mac with Mamp. Don't ask why... or suggest alternate means of executing

Issue: Running php exec through mamp php page with imagemagick's convert on a pdf file to output an image does nothing. No errors returned. When running the same command in console it works. When running gs with php exec it works on a pdf file to extract a single page. When running convert with php exec to convert an image to another image it works. Even when running convert pdf to image with php -r in command line works.

Doesn't Work:

PHP Exec convert pdf: (not works) :(

$pdf_command = "convert input.pdf[0] output.jpg --debug all  2>&1";
exec($pdf_command, $output);
print_r($output);

  • Have you tried to pass an absolute path for input.pdf? Why do you think that an empty command output means an error? You should check the exit status instead (exec's 3rd argument). Commented Nov 5, 2016 at 13:10
  • It is -debug rather than --debug, by the way. Commented Nov 5, 2016 at 13:52
  • Try setting the PATH before calling convert and include /usr/local/bin where homebrew puts all its binaries. Commented Nov 5, 2016 at 13:53

Turns out Apache does not have path to 'gs'.

Two solutions:

  1. Make sure Apache has EnvironmentVariables Path to location of gs. Example: '/usr/local/bin'
  2. Update delegate to call ghostscript with absolute path.
    • Update {{imagemagick-install-dir}}/delegates.xml
    • command=""gs" to command=""/usr/local/bin/gs"
