If you've ever dreamed about restarting PHP from PHP script - here you go.

restart.php

<?php
function restart() {
    global $argv;

    $cargs = [];
    foreach($argv as $arg)
        $cargs[] = strpos($arg, ' ') !== false ? '"'.$arg.'"' : $arg;

    if(substr(PHP_OS, 0, 3) == 'WIN')
        die((new \COM("WScript.Shell"))->Run(PHP_BINARY.' '.implode(' ', $cargs), 0, false));
    else
        die(exec(PHP_BINARY.' '.implode(' ', $cargs).' > /dev/null &'));
}
