有没有办法在不等待命令完成的情况下使用 shell_exec? [英] Is there a way to use shell_exec without waiting for the command to complete?

问题描述

我有一个流程密集型任务，我想在后台运行.

I have a process intensive task that I would like to run in the background.

用户点击一个页面，PHP脚本运行，最后，根据一些条件，如果需要，那么它必须运行一个shell脚本，例如:

The user clicks on a page, the PHP script runs, and finally, based on some conditions, if required, then it has to run a shell script, E.G.:

shell_exec('php measurePerformance.php 47 844 [e-mail]');

目前我使用 shell_exec，但是这需要脚本等待一个输出.有没有什么方法可以在不等待它完成的情况下执行我想要的命令?

Currently I use shell_exec, but this requires the script to wait for an output. Is there any way to execute the command I want without waiting for it to complete?

推荐答案

如何添加.

"> /dev/null 2>/dev/null &"

shell_exec('php measurePerformance.php 47 844 [e-mail] > /dev/null 2>/dev/null &');

注意这也摆脱了 stdio 和 stderr.

Note this also gets rid of the stdio and stderr.
