Php exec command pdftoimage not work - php

Question

I have problem with my code.
My Code look like this:
$destinationFolder = $destinationRootFolder . '/';
// mkdir($destinationFolder,777);
$options = $this->buildOptions($saveAsJpeg, $inputPdf, $destinationFolder);
print_r($options);
// exit;
try {
$command = "/usr/bin/pdfimages ".$options[0]." ".$options[1]." ".$options[2];
echo $command;
// exit;
shell_exec($command);
exec($command);
// $command;
// echo $r;
} catch (ExecutionFailureException $e) {
throw new RuntimeException('PdfImages was unable to extract images', $e->getCode(), $e);
}
code entered first command before it executes it. When the copy command to the console everything works well but does not create php files png.

Answer 1

It sounds like the apache does not have permissions to run it, A few things to check
1) ( if CentOS/RHEL ) Is selinux stoping it, TO temporarly disable it
setenforce 0
Perminetly allow it ( Replace /usr/bin/pdfimages with all files that need access )
chcon -v --type=httpd_sys_content_t /usr/bin/pdfimages
2) Not executible by apache, Try
chmod +x /usr/bin/pdfimages
If nether of thoughs work, What os is your server running?
