PHP - What does "Segmentation fault (core dumped)"-Error means?

I wrote a simple crawler using Simple HTML Dom Parser to scrape some stuff.
我使用 Simple HTML Dom Parser 编写了一个简单的爬虫来抓取一些东西。
It's a simple script only running with 1 process and nothing massive. But after some time it produces a "Segmentation fault (core dumped)"-error,when I am running it in the shell.
这是一个简单的脚本，只运行 1 个进程，没什么大不了的。但是一段时间后，"Segmentation fault (core dumped)"-error,当我在 shell 中运行它时，它会产生一个。
When I run the script in the browser it says
当我在浏览器中运行脚本时，它说
"Error: The connection to the server was reset while the page was loading.".
I have made sure to unset()every variable as soon as possible and also increased the memory_limitin php.ini, but still I get this error :/
我已确保unset()尽快确定每个变量并增加了memory_limitin php.ini，但我仍然收到此错误：/
Does someone know what it means and how to solve it?

I have this problem when a made a recursive loop by accident, so it runs out of memory. But the way it tells me is by making a Segmentation fault (core dumped)error!
当 a 意外进行递归循环时，我遇到了这个问题，因此内存不足。但它告诉我的方式是Segmentation fault (core dumped)犯错误！
So look a the code you most recently wrote and check if you made a error like this! My example was very simple (and stupid). I was just a little to fast to accept the autocomplete's suggestion :)
因此，查看您最近编写的代码并检查您是否犯了这样的错误！我的例子非常简单（而且很愚蠢）。我只是有点快接受自动完成的建议:)
public function getAttendees()
{
return $this->getAttendees();
}
Hope this can help someone in the future
希望这可以帮助将来的某人

If anybody else has the same problem with Simple HTML Dom Parser: In this case the error was caused because of too long webpages. SHDP has a preconfigured "MAX_FILE_SIZE". You have to increase it in the source of simple_html_dom.php. See line:
如果其他人对 Simple HTML Dom Parser 有同样的问题：在这种情况下，错误是由于网页太长造成的。SHDP 有一个预配置的“MAX_FILE_SIZE”。您必须在simple_html_dom.php. 见行：
define('MAX_FILE_SIZE', 600000);

I've had it because free HDD space in VM ended due to too much data in /tmp folder
我已经有了它，因为 VM 中的可用硬盘空间由于 /tmp 文件夹中的数据过多而结束

The 'core dumped' I think just means the program released the memory and exited.
“核心转储”我认为只是意味着程序释放了内存并退出。
A segmentation fault usually occurs when you try and access a part of memory that is not yours to use, or by deferencing an uninitialised or invalid pointer.
当您尝试访问不属于您的部分内存或延迟未初始化或无效的指针时，通常会发生分段错误。
Could you be passing/using a bad handle or overrunning an array somewhere?
您是否可以传递/使用错误的句柄或在某处溢出数组？

I just has same issue. I was doing
我只是有同样的问题。我在做
return $var;
Which caused the error. However returning
这导致了错误。然而返回
return [$var][0];
worked. I'm sure there is a good explanation for this but I don't know it.
工作。我确信对此有一个很好的解释，但我不知道。
