  在网上看大一位网友写的PHP多进程控制的实例,分享个大家:

  declare(ticks=1);

  function sigHandler($signal)

  {

  echo "a child exited\n";

  }

  pcntl_signal(SIGCHLD, sigHandler, false);

  echo "this is " . posix_getpid() . PHP_EOL;

  for($i=0; $i

  {

  $pid = pcntl_fork();

  if($pid == -1)

  {

  echo 'fork failed ' . PHP_EOL;

  }

  else if($pid)

  {

  }

  else

  {

  $pid = posix_getpid();

  echo 'child ' . $pid . ' ' . time() . PHP_EOL;

  sleep(rand(2,5));

  echo 'child ' . $pid . ' done ' . time() . PHP_EOL;

  exit(0);

  }

  }

  do

  {

  $pid = pcntl_wait($status);

  echo 'child quit ' . $pid . PHP_EOL;

  }while($pid > 0);

  echo 'parent done' . PHP_EOL;
