PHP 重写 URL 后获取地址中的参数

.htaccess

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteBase /
# RewriteBase 是文件目录
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d

# RewriteRule 是映射到的实际文件
RewriteRule . /index.php [L]
</IfModule>

url_fn.php

<?php 

$request_url	=	$_SERVER['REQUEST_URI'];	//获取全 URL
// $request_url = substr(strrchr($request_url, "/"), 1);	//直接获得最后一个斜杠后的内容
$get_self	=	$_SERVER['PHP_SELF'];	//获取文件路径
$get_self	=	substr($request_url, 0, strrpos($get_self, "/")); //获取当前目录
$request_url	=	substr($request_url, strlen($get_self)+1);	//截取页面后面参数
$request_url		=	explode("/", $request_url);	//转换获取的内容为数组
$donateName	=	urldecode($request_url[0]);	// 转换 URL 码
$fn_json	=	json_encode($request_url);	//输出 json

 ?>
