$pid = pcntl_fork();
//父進(jìn)程和子進(jìn)程都會(huì)執(zhí)行下面代碼
if ($pid == -1) {
//錯(cuò)誤處理：創(chuàng)建子進(jìn)程失敗時(shí)返回-1.
die('could not fork');
} else if ($pid) {
//父進(jìn)程會(huì)得到子進(jìn)程號(hào)，所以這里是父進(jìn)程執(zhí)行的邏輯
pcntl_wait($status); //等待子進(jìn)程中斷，防止子進(jìn)程成為僵尸進(jìn)程。
} else {

 //子進(jìn)程邏輯
 exit()

}

如上，正常情況下 子進(jìn)程邏輯結(jié)束之后，需要手動(dòng)調(diào)用exit結(jié)束子進(jìn)程。
但是現(xiàn)在的問題是，在workerman里不能手動(dòng)調(diào)用 exit()，否則會(huì)造成整個(gè)進(jìn)程退出。
但是不調(diào)用的話，沒法手動(dòng)結(jié)束子進(jìn)程，并且會(huì)報(bào)錯(cuò)：

怎么解。。求助。。
