php 5.30快速url重写的解决办法

这篇文章主要为大家详细介绍了php 5.30快速url重写的简单示例，具有一定的参考价值，可以用来参考一下。

对此感兴趣的朋友，看看idc笔记做的技术笔记！

代码如下:

 
#-------------- .htaccess start --------------- 
RewriteEngine on 
RewriteRule !\.(js|ico|gif|jpg|png|css|swf|htm|txt)$ index.php 
php_flag magic_quotes_gpc off 
php_flag register_globals off 
#-------------- .htaccess end --------------- 

代码如下:

 
//............ 
Rewrite::__config( 
$config['path'],/*'http://xxxxx/mysite/'URL基础位置*/ 
$config['md_path'],/*'c:/phpsite/www/mysite/modules/'模块文件物理目录*/ 
array( 
'phpinfo' 
) 
); 
Rewrite::__parse(); 
//.......... 

代码如下:

 
<?php 
class Rw_testPk extends Rewrite { 
//这个是前导函数,只要访问到testpk这个页面,这个必然会执行,可用来控制本页面内函数访问权限或本页面全局变量 
public static function init(){ 
//if (!defined('SITE_PASS')){ 
echo self::$linktag.'<br/>';//self::$linktag是页面解析位置路径值,会常使用. 
//} 
} 
//当访问"http://localhost/testpk/"时会执行 
public static function index(){ 
echo 'test'; 
} 
//当访问"http://localhost/testpk/blank"时会执行或写作"http://localhost/testpk/index/blank"一般"index/"都是可以被省略的 
public static function blank(){} 
} 
?> 

代码如下:

 
<?php 
class Rewrite{ 
public static $debug = false;//是否打开调试 
public static $time_pass = 0;//获得模块文件整体执行时间 
public static $version = 2.2; 
public static $pretag = 'Rw_';//模块文件类的名称前缀 
public static $linktag = 'index';//页面链接标记,用来标记解析的是那个链接,可用来控制各种菜单效果和链接访问权限 
protected static $time_start = 0; 
protected static $time_end = 0; 
protected static $physical_path = '';//模块文件的物理路径 
protected static $website_path = '';//模块文件的站点路径,因为可能把站点放大站点的子目录下,如:http://localhost/site/mysite 
protected static $ob_contents = ''; 
protected static $uid = 0;//配合个人主页访问方式 如http://localhost/423/则是访问http://localhost/profile?uid=423 
//允许的系统函数如$allow_sys_fun=array('phpinfo')那么系统将允许链接访问phpinfo内容了,当http://localhost/phpinfo或http://localhost/......./phpinfo时就会直接执行phpinfo这个函数,不需要phpinfo.php模块文件 
private static $allow_sys_fun = array(); 
private static function __get_microtime(){ 
list($usec, $sec) = explode(" ",microtime()); 
return ((float)$usec + (float)$sec); 
} 
//设置调试Rewrite::__debug(true); 
public static function __debug($d = true){ 
static::$debug = $d; 
} 
//配置路径和允许函数 
public static function __config($website_path = '',$physical_path = '',$allow_sys_fun = array()){ 
self::$physical_path = $physical_path; 
self::$website_path = $website_path; 
self::$allow_sys_fun = $allow_sys_fun; 
} 
//调试函数 
public static function __msg($str){ 
if(static::$debug){ 
echo "\n<pre>\n".print_r($str,true)."\n</pre>\n"; 
} 
} 
//解析开始时间 
public static function __start(){ 
self::$time_start = self::__get_microtime(); 
} 
//解析结束时间 
public static function __end($re = false){ 
self::$time_end = self::__get_microtime(); 
self::$time_pass = round((self::$time_end - self::$time_start),6) * 1000; 
if($re){ 
return self::$time_pass; 
}else{ 
self::__msg('PASS_TIME: '.self::$time_pass.' ms'); 
} 
} 
//内部跨模块url解析调用,如在test1.php模块页面中执行了Rwrite::__parseurl('/test2/show')这句,将调用test2.php模块页面中的show方法(Rw_test2这个class的方法) 
public static function __parseurl($url = '',$fun = '',$data = NULL){ 
if(!empty($url)&&!empty($fun)){ 
$p = static::$physical_path; 
if(file_exists($p.$url) || file_exists($p.$url.'.php') ){

include( $p.$url ); 
if( class_exists($fname, false) && method_exists($fname,$fun)){
