使用PHP终止Shell脚本

Question

I'm trying to terminate a shell script using PHP code.

I have created a shell script foo.sh which calls a PHP file

#! /bin/bash

cd /var/www/html/test
php test.php

Following is test.php

<?php
  exec('exit 0');
?>

For some reason the shell script is not exiting.

Answer 1

Your exit(0) in PHP will terminate process with PHP itself, and not parent process (if any). To terminate your bash script, you will need to find it's pid via ps and grep , or, alternatively, use killall :

system('killall foo.sh');
