从命令行运行PHP脚本作为后台进程 [英] Running PHP script from command line as background process

问题描述

我试图在后台通过Linux中的命令行连续运行PHP脚本。我试过命令 php filename.php& ，但似乎脚本执行终止非常快，而它应该保持运行，直到进程终止。

I'm trying to run a PHP script continually in the background via the command line in Linux. I have tried the command php filename.php & but it seems like the script execution terminates very quickly, while it should keep running until the process is terminated.

有任何建议吗？

推荐答案

您确定脚本不包含任何错误？这通常是执行终止非常快，使用 error_reporting（E_ALL）和 ini_set（'display_errors'，'On'）显示脚本可能有的任何错误，那么你可以使用：

Are you sure the script doesn't contain any errors? That's normally what makes "execution terminates very quickly" , use error_reporting(E_ALL) and ini_set('display_errors','On') to display any errors the script may have, then you can use :

nohup php filename.php& - > nohup运行命令，即使会话断开或用户注销。

nohup php filename.php & -> nohup runs a command even if the session is disconnected or the user logs out.

也可以使用：

ignore_user_abort（1）; - >设置客户端断开是否应终止脚本执行

set_time_limit（0）; - >限制最大执行时间，在这种情况下它会运行，直到进程完成或apache重新启动。

You can also use:
ignore_user_abort(1); -> Set whether a client disconnect should abort script execution
set_time_limit(0); -> Limits the maximum execution time, in this case it runs until the process finishes or apache restart.
