Laravel Artisan Queue Ensurer - Set a cron job to run this file periodically to ensure that Laravel's queue is processing all the time. If the queue listener stopped, restart it!

queue-ensure.php

<?php

function runCommand ()
{
    $command = 'php artisan queue:listen > /dev/null & echo $!';
    $number = exec($command);
    file_put_contents(__DIR__ . '/queue.pid', $number);
}

if (file_exists(__DIR__ . '/queue.pid')) {
    $pid = file_get_contents(__DIR__ . '/queue.pid');
    $result = exec('ps | grep ' . $pid);
    if ($result == '') {
        runCommand();
    }
} else {
    runCommand();
}

I also need the shell-script variant... pgrep allows to use it without the pid file.
However you can only run one instance of php artisan queue:work

I use pgrep to only search for the artisan queue:work since my provider uses an alias for php.

#!/bin/bash

# Check if "artisan queue:work" is running
if pgrep -f "artisan queue:work" > /dev/null
then
    echo "queue:work is already running."
    exit 1
else
    echo "Starting queue:work..."
    nohup php artisan queue:work > /dev/null 2>&1 &
    echo "queue:work started."
fi

@CodeAndWeb looks nice, more clean than my code!
