php - shell_exec() command not working locally -


i'm trying run shell command via php. interestingly, script works fine on production server , works when plug in command shell manually. shell_exec() command not work in local dev. environment on os x - returns blank web page instead of pdf supposed generated.

i won't dive specifics of local env. since i'm guessing high-level issue...

the command supposed execute via shell_exec() looks like:

/usr/local/bin/phantomjs --ignore-ssl-errors=true --debug=true ../scripts/renderteamprofile.js https://127.0.0.1/app_dev.php/pdf/enterprise-lpc-enterprise/profile/render /private/var/tmp/pjsk2n16e.pdf

the php:

 public function pdfresponse($url, $script, $remote_filename)  {     $tempfile = tempnam('/tmp', 'pjs');     $tempfilepdf = $tempfile . '.pdf';     rename($tempfile, $tempfilepdf);      # nginx should restrict access localhost url     $urllocal = preg_replace('/^https:..[^\/]+/', 'https://127.0.0.1', $url);      $phantomjs = $this->container->getparameter('testsite.phantomjs_cmd');     $command = $phantomjs.' --debug=true '.$script.' '.$urllocal.' '.$tempfilepdf;     $output = shell_exec($command);     $content = file_get_contents($tempfilepdf);     $response = new response($content, 200);     $response->headers->set('content-type', 'application/pdf');     $response->headers->set('content-disposition',     ('inline; filename="' .    $remote_filename . '"'));     return $response; }
