php使用goto实现自动重启swoole、reactphp、workerman服务的代码

?php

//index.php

require './vendor/autoload.php';

Restart:

$pid = pcntl_fork();

if ($pid > 0) {
  $fd = inotify_init();
  $watch_descriptor = inotify_add_watch($fd, './src/', IN_MODIFY);

  $events = inotify_read($fd);

  posix_kill($pid, SIGTERM);
  
  fclose($fd);

  pcntl_wait($status);

  goto Restart;
} elseif ($pid == 0) {
  \Church\Application::run();
} else {
  exit(0);
}

?php
namespace Church;
