Php exec命令pdftoimage不起作用

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.

It also does not work

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?
