How to check if mod_rewrite is enabled in php?
提问by Ties
I was wondering if it is possible to check if mod_rewriteis enabled on ApacheAND IISin PHP.
我想知道是否可以检查Apache和IIS中mod_rewrite是否启用了.PHP
ModRewritefor IIS exists. Check it here.
存在用于 IIS 的ModRewrite。检查它here。
So, I'm looking for a PHP script that checks for mod_rewriteon Apacheand IIS.
所以，我在找一个PHP脚本，支票mod_rewrite上的Apache和IIS。
Does anyone know such script or can write one?
有谁知道这样的脚本或可以写一个？
Especially for Microsoft IIS.

If you're using mod_php, you can use apache_get_modules(). This will return an array of all enabled modules, so to check if mod_rewriteis enabled, you could simply do
如果您使用的是 mod_php，则可以使用apache_get_modules(). 这将返回所有已启用模块的数组，因此要检查是否mod_rewrite已启用，您可以简单地执行
in_array('mod_rewrite', apache_get_modules());
Unfortunately, you're most likely trying to do this with CGI, which makes it a little bit more difficult.
不幸的是，您很可能会尝试使用 CGI 来执行此操作，这会增加一些难度。
You can test it using the following, though
不过，您可以使用以下方法对其进行测试
strpos(shell_exec('/usr/local/apache/bin/apachectl -l'), 'mod_rewrite') !== false
If the above condition evaluates to true, then mod_writeis enabled.
如果上述条件评估为true，则mod_write启用。

Copy this piece of code and run it to find out.
复制这段代码并运行它以找出答案。
<?php
if(!function_exists('apache_get_modules') ){ phpinfo(); exit; }
$res = 'Module Unavailable';
if(in_array('mod_rewrite',apache_get_modules()))
$res = 'Module Available';
?>
<html>
<head>
<title>A mod_rewrite availability check !</title></head>
<body>
<p><?php echo apache_get_version(),"</p><p>mod_rewrite $res"; ?></p>
</body>
</html>

I like Christian Roy's solution:
### .htaccess
<IfModule mod_rewrite.c>
# Tell PHP that the mod_rewrite module is ENABLED.
SetEnv HTTP_MOD_REWRITE On
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# The rest of your rewrite rules here
</IfModule>
Then, you can check in your PHP code for
然后，您可以检查您的 PHP 代码
array_key_exists('HTTP_MOD_REWRITE', $_SERVER);
No idea if this works also with IIS (I have no way to check) but the odds are good.
不知道这是否也适用于 IIS（我无法检查），但可能性很大。

Upload a file called info.php with this code and run it:
使用以下代码上传一个名为 info.php 的文件并运行它：
<?php
phpinfo();
Search for mod_rewrite on the page, and see if you can find it under Loaded Modules.
在页面上搜索 mod_rewrite，看看是否可以在 Loaded Modules 下找到它。

don't make it so difficult you can simply find in phpinfo();
不要让它变得如此困难，你可以简单地找到 phpinfo();
Hope helpful!
希望有帮助！

<?php
phpinfo();
?>
Look under Configuration in the apache2handler in the Loaded Modules row.
在 Loaded Modules 行中查看 apache2handler 中的 Configuration。
This is simple and works.
这很简单而且有效。
<?php foreach( apache_get_modules() as $module ) echo "$module<br />"; ?>

This is my current method of checking if Mod_rewrite enabled for both Apache and IIS
这是我当前检查是否为 Apache 和 IIS 启用 Mod_rewrite 的方法
/**
* --------------------------------------------------------------
* MOD REWRITE CHECK
* --------------------------------------------------------------
* - By A H Abid
* Define Constant for MOD REWRITE
*
* Check if server allows MOD REWRITE. Checks for both
* Apache and IIS.
*
*/
if( function_exists('apache_get_modules') && in_array('mod_rewrite',apache_get_modules()) )
$mod_rewrite = TRUE;
elseif( isset($_SERVER['IIS_UrlRewriteModule']) )
$mod_rewrite = TRUE;
else
$mod_rewrite = FALSE;
define('MOD_REWRITE', $mod_rewrite);
It works in my local machine and also worked in my IIS based webhost. However, on a particular apache server, it didn't worked for Apache as the apache_get_modules() was disabled but the mod_rewrite was enable in that server.
它适用于我的本地机器，也适用于我的基于 IIS 的网络主机。但是，在特定的 apache 服务器上，它不适用于 Apache，因为 apache_get_modules() 被禁用，但在该服务器中启用了 mod_rewrite。

Two lines of code:
两行代码：
$isEnabled = in_array('mod_rewrite', apache_get_modules());
echo ($isEnabled) ? 'Enabled' : 'Not enabled';

You can get a list of installed apache modules, and check against that. Perhaps you can check if its installed by searching for its .dll (or linux equivalent) file.
您可以获得已安装apache 模块的列表，并进行检查。也许您可以通过搜索其 .dll（或 linux 等效文件）文件来检查它是否已安装。
