如何阻止php中的无限递归函数占用所有可用内存并最终使笔记本电脑崩溃? [英] How to stop an infinite recursive function in php from eating all the available memory and eventually crashing the laptop?

问题描述

我这里有一个简单的无限递归代码:

I have a simple infinite recursive code here:

        <?php

        function test(){
             test();
        }
        test();

当我尝试运行它时，它占用了所有内存，最终我的笔记本电脑挂了.我正在寻找的是一种方法来抓住这个并阻止机器挂起.php 中是否有相同的错误处理程序?

When I try to run the same, it eats up all the memory and eventually my laptop hangs. What I am looking for is a way to catch this and stop the machine from hanging. Is there any Error handler in php for the same?

我读过并尝试过的事情:将 max_execution_time 设置为 5秒并捕获错误行号.此项工作按建议进行.

Things I have read and tried: setting max_execution_time to lets say 5 secs and catch the error line no. This dint work as proposed.

还有什么其他方法可以捕捉和阻止这种情况?

Any other way to catch and stop this?

推荐答案

<?php

    function test($tryCount=1){
         $tryCount++;
         //terminate recursive if more than 10 times loop
         if($tryCount > 10){
             return false;
         }
         test($tryCount);
    }
    test();
