我在使用preg_match_all的时候匹配一个比较长串的字符串的时候，apache就会崩溃，最后显示页面加载失败
后来上网查了一下说是要把
ini_set('pcre.backtrack_limit', 999999999);
ini_set('pcre.recursion_limit', 99999);
设成这样的，但是发现并没有什么用，折腾了好长时间没有办法解决，恳请大神们指点
下面的链接是我参考原文，上面两个解决思路也是从下面链接上复制而来的

那么你的 规则串 和 待匹配文本 都是什么样自的呢?
凡事都有个度，超过了自然就会出问题
比如 向后引用 不宜超过 9 个，超过了就会产生歧义
数据库的 Text 类型 只能存储 64k 内容，preg 函数在实现时也会考虑这个因素，预留巨大的状态转移表空间也是一种浪费

正则表达式是这样的
$pattern = '/\{(\{(\w+)(?:(?!\{\{).|\n)+\{\/\2\})\}/'; 字符串是：
<html> <head> <title>TODO supply a title</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <body> {{foreach ($message1 as $key1 => $value1)} {$key1} => {foreach ($value1 as $key2 => $value2)} {foreach ($value2 as $key3 => $value3)} {if($value3 == 0)} <p>{$key3}=>female</p> {else if($value3 == 1)} <p>{$key3}=>male</p> {else} <p>{$key3}=>{$value3}</p> {/if} {/foreach} {/foreach} {/foreach}} </body></html>

$this->content就是上面的字符串的内容，在运行preg_match_all的时候，程序就崩溃了

$this->content就是上面的字符串的内容，在运行preg_match_all的时候，程序就崩溃了
再补充一点，这个正则表达式是要匹配{{foreach ...}........{/foreach}}的内容
另外我测试过了，把上面的字符串长度剪短，变成下面这样的，preg_match_all就可以正常的运行，
<html> <head> <title>TODO supply a title</title> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> </head> <body> {{foreach ($message1 as $key1 => $value1)} {$key1} => {foreach ($value1 as $key2 => $value2)} {foreach ($value2 as $key3 => $value3)} <p>{$key3}=>{$value3}</p> {/foreach} {/foreach} {/foreach}} </body></html> 但是如果剪短的话，就不能完成我的需求，请大神指点

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
