Asynchronous shell exec in PHP

Question

I\'ve got a PHP script that needs to invoke a shell script but doesn\'t care at all about the output. The shell script makes a number of SOAP calls and is slow to complete,

Answer 1

I also found Symfony Process Component useful for this.

use Symfony\Component\Process\Process;

$process = new Process('ls -lsa');
// ... run process in background
$process->start();

// ... do other things

// ... if you need to wait
$process->wait();

// ... do things after the process has finished

See how it works in its GitHub repo.
