目前我的解决方案是:
exec('PHP file.PHP >/dev/null 2>&1 &');
并在file.PHP中
if (posix_getpid() != posix_getsid(getmypid())) posix_setsid();
我有什么方法可以用exec做到这一点?

不能用exec()(也不是shell_exec()或system())来做到这一点
如果您安装了pcntl extension,它将是:
function detached_exec($cmd) { $pid = pcntl_fork(); switch($pid) { // fork errror case -1 : return false // this code runs in child process case 0 : // obtain a new process group posix_setsid(); // exec the command exec($cmd); break; // return the child pid in father default: return $pid; } }
这样叫:
$pid = detached_exec($cmd); if($pid === FALSE) { echo 'exec Failed'; } // do some work // kill child posix_kill($pid,SIGINT); waitpid($pid,$status); echo 'Child exited with ' . $status;@H_301_9@
