发现个PHP很奇怪的问题？导致所有网站打不开，求助！

[qaz952727]

我用的VPS是linux系统，使用的lnmp一键安装包搭建的环境。

最近安装了一个wordpress主题，然后修改主题的一些代码，改着改着改完也没出现什么问题，后来晚上发现网站打不开，没过几分钟又能打开，点几下又打不开，也没提示错误，谷歌浏览器提示101错误什么的，但刷新一下错误提示又是不一样的。使用第三方工具检测http状态码有时是200（此时明明打不开的），有时是302。总之网站的状况就是一时能打开，一时打不开，两种情况都在几十秒几分钟之间，没啥规律，然后打开同一服务器下的其他网站，发现也是同样的问题，这就奇怪了，如果是因为之前修改wordpress的代码出错而打不开那也是一个网站的问题吧，怎么会连其他网站都一起牵涉到的呢？目录都不同，程序也不同。

试过重启nginx，PHP ，VPS 都没解决

不知大神们明白我的意思没，网站A用是wordpress程序，出现这问题前曾修改过主题代码，不过运行了几个小时都没出问题，到了晚上我就发现问题了，A站在 /home/www/A 目录下， B在/home/www/B 目录下 ，A网站打不开B网站也跟着打不开，A能打开B也能打开。

还有一点就是当时我跑去主题作者的主页，发现他的网站也打不开。

这种诡异吗？是啥问题啊？求指教谢谢！

装个新的试试

php 我觉得还有很多不完善的地方.如:我在通过ISAPI方式使用时(php版本:5.2.17),在POST上传文件过程中,如果间隔一段时间(几分钟或更长时间以后)再次提交,会随机地导致WEB服务器崩溃.PHP的BUG和稳定性还有待完善.

换一个主题模板就可以正常访问，其他网站也正常了。

发现 functions.php 被加密过的了 求解密谢谢

<?php
function wp_strimwidth($str ,$start , $width ,$trimmarker ){
	$output = preg_replace('/^(?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$start.'}((?:[\x00-\x7F]|[\xC0-\xFF][\x80-\xBF]+){0,'.$width.'}).*/s','\1',$str);
	return $output.$trimmarker;
