cocur/background-process

Start processes in the background that continue running when the PHP process exists.

Installation

You can install cocur/background-process using Composer:

$ composer require cocur/background-process:@stable

In a production environment you should replace @stable with the version you want to use.

Usage

The following example will execute the command sleep 5 in the background. Thus, if you run the following script either in the browser or in the command line it will instantley finish executing.

use Cocur\BackgroundProcess\BackgroundProcess;

$process = new BackgroundProcess('sleep 5');
$process->run();

You can retrieve the process ID (PID) of the process and check if it's running:

use Cocur\BackgroundProcess\BackgroundProcess;

$process = new BackgroundProcess('sleep 5');
$process->run();

echo sprintf('Crunching numbers in process %d', $process->getPid());
while ($process->isRunning()) {
    echo '.';
    sleep(1);
}
echo "\nDone.\n";

If the process runs you can stop it:

// ...
if ($process->isRunning()) {
    $process->stop();
}

Please note: If the parent process continues to run while the child process(es) run(s) in the background you should use a more robust solution, for example, the Symfony Process component.
