php快速url重写更新版[需php 5.30以上

发布时间:2016-11-25 15:57

类只能php教程 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和属性 可以调用其他url中的模块了 也使得模块与模块间或页面与页面间的函数简化共享得以实现

.htaccess文件写法:
复制代码 代码如下:
#-------------- .htaccess start ---------------

RewriteEngine on
RewriteRule !.(js|ico|gif|jpg|png|css教程|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类文件在index.php前面部分加载了.4.页面模块文件位置及写法无误):
复制代码 代码如下:
//............

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

//..........

模块文件写法:

testPk.php
复制代码 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(){}
}
?>

class.rewrite.php;
复制代码 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);

//配置路径和允许函数

}

//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(){

//解析结束时间
public static function __end($re = false){

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){

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

网上的PHP端escape unescape函数建议不要用,它把中英文混合时的英文过滤掉了,我是莫名其妙了N久啊,建议用unicode_urldecode这个。


function unicode_urldecode($url)
{
preg_match_all('/%u([[:alnum:]]{4})/', $url, $a);
foreach ($a[1] as $uniord)
{
$dec = hexdec($uniord);
$utf = '';
if ($dec < 128)
{
$utf = chr($dec);
}
else if ($dec < 2048)
{
$utf = chr(192 + (($dec - ($dec % 64)) / 64));
$utf .= chr(128 + ($dec % 64));
}
else
{
$utf = chr(224 + (($dec - ($dec % 4096)) / 4096));
$utf .= chr(128 + ((($dec % 4096) - ($dec % 64)) / 64));
$utf .= chr(128 + ($dec % 64));
}
$url = str_replace('%u'.$uniord, $utf, $url);
}
return urldecode($url);
}

再就是编码格式的转换,这主要涉及数据的存储和客户端返回,用iconv就搞定,这个函数似乎是从C++中借鉴来的

$list = array(
        array('id'=>107,'title'=>'aaa'),
        array('id'=>106,'title'=>'bbb'),
        array('id'=>105,'title'=>'ccc'),
        array('id'=>104,'title'=>'ccc'),
        array('id'=>103,'title'=>'ddd'),
        array('id'=>102,'title'=>'eee'),
        array('id'=>101,'title'=>'fff'),
       
        );


function assoc_title($arr, $key) {
                        $tmp_arr = array();
                        foreach($arr as $k => $v) {
                        if(in_array($v[$key], $tmp_arr)) {
                                unset($arr[$k]);
                        } else {
                                $tmp_arr[] = $v[$key];
                        }
                }
                        return $arr;
}//assoc_title end
$key_title='title';
assoc_title($list, $key_title);
print_r($list);

/*
 方法二用 array_unique()
 array_unique() 函数移除数组中的重复的值,并返回结果数组。 当几个数组元素的值相等时,只保留第一个元素
 
*/
$sarray = array('0','111cn.net','www.111cn.net','0');
$s = array_unique($sarray);
print_r($s);

/*
得出结果为
Array
(
    [0] => 0
    [1] => 111cn.net
    [2] => www.111cn.net
)
*/

 

简单说一下就是
-> 调用对象的成员
=> 指定下标

下面来看几个实例关于-> 与=>代码,让你更清楚是什么用法与功能并且有什么区别了。
*/
// =>用法,可用到数组array,赋值与foreach赋值

$array = array("addr" => "www.111cn.net","tel" => "11111111");

print_r($array);

/*
结果为
Array
(
    [addr] => www.111cn.net
    [tel] => 11111111
)
*/

//用来foreach实例

foreach( $array as $v =>$_v )
{
 echo $_v,'<br />';
}

/*
结果
www.111cn.net
11111111

*/
