升级到 PHP5.5 时 Wordpress 崩溃答案

【问题标题】：Wordpress crashes when upgrading to PHP5.5升级到 PHP5.5 时 Wordpress 崩溃
【发布时间】：2016-02-29 15:12:35
【问题描述】：

我在 Debian 7 服务器上使用 nginx 托管了一个 wordpress。昨天我从 PHP5.4 升级到 PHP5.5，它使所有托管的 wordpress 网站崩溃。其他使用 PHP 的网站效果很好，但 wordpress 不行。

我尝试设置define('WP_DEBUG', true);，但没有显示错误。

我也尝试过<?php phpinfo(); ?>，但仍然是空白页。

Nginx 虚拟主机

server {

    listen 80;

    server_name thinkcreate.fr www.thinkcreate.fr;

    root /var/www/blog/thinkcreate;
    index index.php index.html index.htm;

    access_log /var/log/nginx/thinkcreate.access.log;
    error_log /var/log/nginx/thinkcreate.error.log;

    location / {
        try_files $uri $uri/ /index.php?q=$uri&$args;
    }

    error_page 404 /404.html;

    error_page 500 502 503 504 /50x.html;
    location = /50x.html {
        root /usr/share/nginx/html;
    }

    location ~ \.php$ {
        try_files $uri =404;
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
    }

}

错误日志中没有任何内容。

有什么想法吗？

【问题讨论】：

您所说的“使网站崩溃”任何错误或只是空白页是什么意思？如果 phpinfo 为空，则 WP_DEBUG 也不会显示任何内容
我的日志中也没有错误提示...
你试过这个吗？在其中一个 WP 站点中，重命名 .htaccess 文件，创建一个包含 phpinfo() 内容的新文件 test.php，输出结果是什么？
仍然是空白页... 在升级过程中，PHP 询问我是否要保留我的 php.ini (PHP 5.4) 配置。我说是的，所以我有一个运行我的“旧”php.ini conf 的 PHP 5.5。也许那里有什么东西。
空白页或请求超时？您可以打开您的 nginx 虚拟主机或服务器配置并打开文件error_log 指向吗？最好使用 nginx 配置和 access_log 和 error_log 文件的最后 10-20 行来更新您的答案。您的请求是否在access_log 中进行跟踪？

【解决方案1】：

我的 ISP 刚刚将我的服务器从 5.3 升级到 5.5 Php 解释器。当我进行代码修复/更新时，我能够在两者之间移动（使用 htaccss）。就我而言，由于我的大部分页面都是交互式的，因此有必要重写页面的某些部分以符合 5.5 处理页面间变量的要求。否则页面会出现空白（没有来自数据库的信息）或在页面上传递错误。我对 wordpress 了解不多，但如果你只处理 php 方面的事情，也许你只需要在这里和那里进行一些调整。我的整个域现在都在加速。我花了大约 4 周的时间来更新我的代码，但我的域又非常大。

【讨论】：

您最终需要在哪里做出最大的改变？你能举出一些例子来帮助网站重新运行吗？
