PHP 简单 HTML DOM 解析器内存泄漏

Question

我正在使用 PHP Simple HTML DOM Parser它消耗了大量内存(使用 memory_get_usage 发现)!我试过unsetting它，但它什么也没做。

Answer 1

见 http://simplehtmldom.sourceforge.net/manual_faq.htm

Q: This script is leaking memory seriously... After it finished running, it's not cleaning up dom object properly from memory..

A: Due to php5 circular references memory leak, after creating DOM object, you must call dom->clear() to free memory if call file_get_dom() more then once.

Example:

$html = file_get_html(...);  // do something...  
$html->clear(); 
unset($html);

当您在循环中使用此库时，会经常发生这种情况。
