本文实例讲述了PHP实现的多进程控制。分享给大家供大家参考，具体如下：
自己写了个多进程控制的框架代码，留着备查
代码语言：javascript复制declare(ticks=1);
function sigHandler($signal)
{
echo "a child exitedn";
}
pcntl_signal(SIGCHLD, sigHandler, false);
echo "this is " . posix_getpid() . PHP_EOL;
for($i=0; $i<3; $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;
