這個(gè)類只能php 5.30以上的版本才能使用,繼承了上一個(gè)版本的快速重定向的特點(diǎn)(單獨(dú)類,全部使用靜態(tài)調(diào)用),增添了一個(gè)很重要的功能和屬性 可以調(diào)用其他url中的模塊了 也使得模塊與模塊間或頁面與頁面間的函數(shù)簡(jiǎn)化共享得以實(shí)現(xiàn)
.htaccess文件寫法:
復(fù)制代碼 代碼如下:
#-------------- .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 ---------------
重寫功能引入:讓站點(diǎn)根目錄的index.php末尾寫上下列代碼,重寫就開啟了(正常條件:1.apache的重寫配置成功,且開啟了.htaccess支持的.2.站點(diǎn)根目錄的.htaccess文件設(shè)置好了.3.class.rewrite.php類文件在index.php前面部分加載了.4.頁面模塊文件位置及寫法無誤):
復(fù)制代碼 代碼如下:
//............
Rewrite::__config(
$config['path'],/*'http://xxxxx/mysite/'URL基礎(chǔ)位置*/
$config['md_path'],/*'c:/phpsite/www/mysite/modules/'模塊文件物理目錄*/
array(
'phpinfo'
)
);
Rewrite::__parse();
//..........
模塊文件寫法:
testPk.php
復(fù)制代碼 代碼如下:
<?php
class Rw_testPk extends Rewrite {
//這個(gè)是前導(dǎo)函數(shù),只要訪問到testpk這個(gè)頁面,這個(gè)必然會(huì)執(zhí)行,可用來控制本頁面內(nèi)函數(shù)訪問權(quán)限或本頁面全局變量
public static function init(){
//if (!defined('SITE_PASS')){
echo self::$linktag.'<br/>';//self::$linktag是頁面解析位置路徑值,會(huì)常使用.
//}
}
//當(dāng)訪問"http://localhost/testpk/"時(shí)會(huì)執(zhí)行
public static function index(){
echo 'test';
}
//當(dāng)訪問"http://localhost/testpk/blank"時(shí)會(huì)執(zhí)行或?qū)懽?http://localhost/testpk/index/blank"一般"index/"都是可以被省略的
public static function blank(){}
}
?>
class.rewrite.php;
復(fù)制代碼 代碼如下:
