http RewriteCond 和 RewriteRule

我需要重写 URL，例如 http://www.example.com/search.php?abc 到http://www.example.com/abc 使用下面的规则，但它不起作用，为什么不匹配？

RewriteCond %{REQUEST_URI} ^search.php
RewriteRule ^search.php?q=([-0-9a-zA-Z]+) $1

I need to rewrite URL like http://www.example.com/search.php?abc
to http://www.example.com/abc
using the rules below, but it doesn't work, why doesn't it match?

RewriteCond %{REQUEST_URI} ^search.php
RewriteRule ^search.php?q=([-0-9a-zA-Z]+) $1

%{REQUEST_URI} 始终以 / 开头。因此 RewriteCond %{REQUEST_URI} ^search.php 永远不会匹配。
重写规则指令
<块引用>
Pattern 是 Perl 兼容的正则表达式。在第一个 RewriteRule 上，它应用于请求的（%-解码）URL 路径；后续模式将应用于最后匹配的 RewriteRule 的输出。
? 表示在未转义时匹配一个或不匹配前一个字符。所以你的 ^search.php?q=... 将匹配：
- search.phpq=...
- search.phq=...

？扩展了(
也是 0 或 1 量词
还有量词最小化器

你必须这样做：

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} ^/([\w]+)/?$ [NC]
RewriteRule ^ search.php?q=%1 [L,QSA]

RewriteCond %{REQUEST_URI} ^/search.php [NC]
RewriteCond %{QUERY_STRING} ^q=([\w\d-]+)$ [NC]
RewriteRule ^ /%1? [L,R=301]

标记NC（nocase）：flag_nc ^{Apache 文档}
标志 L（最后一个）： flag_l ^{Apache 文档}

%{REQUEST_URI} always has a / at the start. so RewriteCond %{REQUEST_URI} ^search.php will never match.
RewriteRule Directive
Pattern is a perl compatible regular expression. On the first RewriteRule it is applied to the (%-decoded) URL-path of the request; subsequent patterns are applied to the output of the last matched RewriteRule.
? means match for one or none of previous character when not escaped. So your ^search.php?q=... would match:
- search.phpq=...
- search.phq=...

from PCRE man pages

? extends the meaning of (
also 0 or 1 quantifier
also quantifier minimizer

You will have to do this:

Options +FollowSymLinks
RewriteEngine On

RewriteCond %{ENV:REDIRECT_STATUS} 200
RewriteRule ^ - [L]

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-l
RewriteCond %{REQUEST_URI} ^/([\w]+)/?$ [NC]
RewriteRule ^ search.php?q=%1 [L,QSA]

RewriteCond %{REQUEST_URI} ^/search.php [NC]
RewriteCond %{QUERY_STRING} ^q=([\w\d-]+)$ [NC]
RewriteRule ^ /%1? [L,R=301]
