Php 使用preg_split重置Apache连接

我在Apache/2.2.25（Win32）和PHP/5.4.10中遇到了一个非常奇怪的行为

我有这个密码

$regex         = '/((<(([^<>]|<[^<>]*>)*)>\s*)+)/s';
$parts         = preg_split( $regex, $content, null, PREG_SPLIT_OFFSET_CAPTURE | PREG_SPLIT_NO_EMPTY );

$content=我可以通过将ThreadStackSize增加到8MB而不是默认的1MB Windows值来解决这个问题，您只需要将这些行添加到Apache conf文件中

<IfModule mpm_winnt_module>
   ThreadStackSize 8388608
</IfModule>
