PHP 不处理堆栈溢出?

2022-01-12 00:00:00 stack-overflow segmentation-fault crash php

当我刚尝试以下 PHP 代码时，我感到很惊讶:

I was surprised when I just tried the following PHP code:

function foo()
{
    foo();
}
foo();

我预计会收到500:内部服务器错误".相反，连接立即关闭(未收到任何字节)，并且日志文件显示 apache 段错误.怎么回事?这是 PHP 中的一个已知错误吗?我缺少一些配置选项吗?因为每次意外堆栈溢出都会导致进程崩溃，嗯……我认为这是非常不可接受的.

I expected to get "500: Internal server error". Instead the connection was closed immediately (no bytes received), and the log files show that apache segfaulted. WTF? Is this a known bug in PHP? Are there some configuration options that I'm missing? Because a crashed process for every accidental stack overflow is, well... pretty unacceptable, I think.

推荐答案

PHP 无法解决这个问题，它只会进入无限循环并产生分段错误.

PHP is not able to deal with this, it will just go into an infinite loop and produce a segmentation fault.
