php 友好URL的实现（吐血推荐）

<?php
/**
* 获得友好的URL访问
*
* @access public
* @return array
*/
function getQueryString(){
$_SGETS = explode("/",substr($_SERVER['PATH_INFO'],1));
$_SLEN = count($_SGETS);
$_SGET = $_GET;
for($i=0;$i<$_SLEN;$i+=2){
if(!empty($_SGETS[$i]) && !empty($_SGETS[$i+1])) $_SGET[$_SGETS[$i]]=$_SGETS[$i+1];
}
$_SGET['m'] = !empty($_SGET['m']) && is_string($_SGET['m']) ? trim($_SGET['m']).'Action' : 'indexAction';
$_SGET['a'] = !empty($_SGET['a']) && is_string($_SGET['a']) ? trim($_SGET['a']) : 'run';
return $_SGET;
}
/**
* 生成链接URL

RewriteEngine on
RewriteCond $1 !^(index\.php|css|pics|themes|js|robots\.txt)
RewriteRule ^(.*)$ index.php/$1 [L]
