PHP 内存不足 - 使 Apache 崩溃? [英] PHP Out of Memory - Crashes Apache?

问题描述

我正在运行 PHP 5.3.0 版和 Apache:2.2.11

I am running PHP version 5.3.0 and Apache: 2.2.11

当我运行消耗大量内存的 PHP 脚本时(我认为) - 大循环等.我的 Apache Web 服务器报告崩溃?！

When I run PHP scripts that consume a lot of memory (I think) - large loops etc. My Apache web server reports a crash?!

[Sat Jan 02 00:51:30 2010] [notice] Parent: child process exited with status 255 -- Restarting.

我需要在某处增加内存吗?我目前将内存设置为

Do I need to increase memory somewhere? I currently have memory set to

memory_limit = 512M 

PHP 没有抱怨过这个问题，所以我在想它是别的什么?

PHP hasn't complained about this so I am thinking its something else?

谢谢大家

有问题的脚本.我已删除该网址.

Update 2

Script in question. I've removed the URL.

<?php error_reporting(E_ALL);

set_time_limit(300000);

echo 'start<br>';

include_once('simple_html_dom.php');

$FileHandle = fopen('tech-statistics3.csv', 'a+') or die("can't open file");

for($i =1; $i < 101; $i ++){
 // Create DOM from URL
 $html = file_get_html("http://www.x.com/$i");

 foreach($html->find('div[class=excerpt]') as $article) {

  $item0 = $article->children(1)->children(1)->children[0]->plaintext;

  $item1 = $article->children(1)->children(1)->children[0]->plaintext;

  $item2 = $article->children(1)->children(0)->children(0)->children(0)->plaintext;

  //$item3 = $article->children(1)->children(0)->children(0)->children[1]->children(0)->next_sibling();

  $stringa = trim($item0).",".trim($item1).",".trim($item2)."\r\n";

  fwrite($FileHandle, $stringa);

  echo $stringa.'<br>';
  echo '------------>'.$i;
 }
}

fclose($FileHandle);

echo '<b>End<br>';

?>

我正在使用 PHP Simple HTML DOM Parser，我刚刚发现了这个:

Update 3

I am using the PHP Simple HTML DOM Parser and I have just found this:

http://simplehtmldom.sourceforge.net/manual_faq.htm#memory_leak

我想我应该清除内存，否则它会崩溃.立即测试.

I think I should be clearing memory otherwise it will crash. Testing now.

是的，这是内存泄漏！:)

Yep, it was a memory leak! :)

推荐答案

由于没有关闭在 for 循环中反复使用的资源以及脚本导致的内存泄漏，Apache 崩溃了使用递归.

Apache was crashing due to a memory leak which was caused by not closing a resource that was being used again and again in a for loop, as well as the script making use of recursion.
