php快速url重写更新版[需php 5.30以上]

前端之家收集整理的这篇文章主要介绍了php快速url重写更新版[需php 5.30以上]前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。

对于apache的rewrite模块打开和设置则非本文主题,请见其他文章详解. 这个类只能PHP 5.30以上的版本才能使用,继承了上一个版本的快速重定向的特点(单独类,全部使用静态调用),增添了一个很重要的功能属性 可以调用其他url中的模块了 也使得模块与模块间或页面页面间的函数简化共享得以实现 .htaccess文件写法:
<div class="codetitle"><a style="CURSOR: pointer" data="49555" class="copybut" id="copybut49555" onclick="doCopy('code49555')"> 代码如下:

<div class="codebody" id="code49555">
#-------------- .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 ---------------

重写功能引入:让站点根目录的index.PHP末尾写上下列代码,重写就开启了(正常条件:1.apache的重写配置成功,且开启了.htaccess支持的.2.站点根目录的.htaccess文件设置好了.3.class.rewrite.PHP文件在index.PHP前面部分加载了.4.页面模块文件位置及写法无误):
<div class="codetitle"><a style="CURSOR: pointer" data="41269" class="copybut" id="copybut41269" onclick="doCopy('code41269')"> 代码如下:
<div class="codebody" id="code41269">
//............ 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(); //..........

模块文件写法: testPk.PHP
<div class="codetitle"><a style="CURSOR: pointer" data="19243" class="copybut" id="copybut19243" onclick="doCopy('code19243')"> 代码如下:
<div class="codebody" id="code19243">
<?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::$linktag.'
';//self::$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(){}
}
?>

class.rewrite.PHP;
<div class="codetitle"><a style="CURSOR: pointer" data="58764" class="copybut" id="copybut58764" onclick="doCopy('code58764')"> 代码如下:
