Question

我正在使用Apache 2.0.50和PHP 5.2.11运行WAMP 2.2并且我查看了我的phpinfo并且我找不到SCRIPT_URI or SCRIPT_URL我尝试将此脚本添加到我的httpd.conf文件中以获取apache并且它没有'工作。任何人都有SCRIPT_URI or SCRIPT_URL对我的phpinfo的任何想法？我需要它用于我在本地计算机上运行的站点。

我的php.ini文件中是否有必要执行此操作？

Answer 1

首先解决方案：我认为这是.htaccess与虚拟主机的区别。如果您在RewriteRule中使用.htaccess，则会设置REDIRECT_URL，而如果您在主apache配置中的虚拟主机中使用它们，则会设置SCRIPT_URL。我的修复非常务实：

if(array_key_exists('SCRIPT_URL',$_SERVER)){
  $url = $_SERVER['SCRIPT_URL'];
  }
elseif(array_key_exists('REDIRECT_URL',$_SERVER)){
  $url = $_SERVER['REDIRECT_URL'];
  }
else throw...;

背景说明：

我刚刚并排比较两台服务器，一台（Mint 16，即Ubuntu 13.10）REDIRECT_URL可用（SCRIPT_URL 不）和另一个（Ubuntu 14.04），其中REDIRECT_*个变量都没有设置，但SCRIPT_URL可用相同的信息。

它们是Apache 2.4.6与2.4.7，以及PHP 5.5.3-1ubuntu2.6与5.5.9-1ubuntu4.3。我只是将phpinfo()输出并排比较，除了库中的次要版本更改它们基本相同之外，除了以用于REDIRECT与SCRIPT $SERVER变差！（要彻底：Mint 16机器安装了mcrypt，而Ubuntu 14没有，而Ubuntu 14安装了readline，而Mint 16机器没有安装。）

最大的区别是设置SCRIPT_URL的服务器在虚拟主机中具有RedirectMatch，并且在脚本名称之前需要显式的正斜杠：

RewriteRule ^.*$ /main.php [NC,L]

而我设置REDIRECT_URL的所有其他服务器都有.htaccess文件中的规则，并且不需要正斜杠：

RewriteRule ^.*$ main.php [NC,L]

（在任何一种情况下我都没有明确设置RewriteBase，但the manual entry似乎暗示我不需要它的原因，这也向我建议机制可能与不同的环境变量不同得到设定。）

Answer 2

在上面的脚本中添加了这一行，现在它可以正常运行RewriteEngine On

我的phpinfo中没有SCRIPT_URI或SCRIPT_URL
