PHP伪静态隐藏传递的参数名的四种方法

　　PHP伪静态的使用主要是为了隐藏传递的参数名，今天介绍的PHP伪静态的方法总共有四种方法以加深对PHP伪静态的了解。

　　伪静态方法一：

<?php

//伪静态方法一

// localhost/php100/test.php?id|1@action|2

$Php2Html_FileUrl = $_SERVER["REQUEST_URI"];

echo $Php2Html_FileUrl." ";

// /php100/test.php?id|1@action|2

$Php2Html_UrlString = str_replace("?","",str_replace("/", "", strrchr(strrchr($Php2Html_FileUrl, "/"),"?")));

echo $Php2Html_UrlString." ";

// id|1@action|2

$Php2Html_UrlQueryStrList = explode("@", $Php2Html_UrlString);

print_r($Php2Html_UrlQueryStrList);

// Array ( [0] => id|1 [1] => action|2 ) echo " ";

foreach($Php2Html_UrlQueryStrList as $Php2Html_UrlQueryStr) {

$Php2Html_TmpArray = explode("|", $Php2Html_UrlQueryStr);

print_r($Php2Html_TmpArray);

// Array ( [0] => id [1] => 1 ) ; Array ( [0] => action [1] => 2 )

echo " ";

$_GET[$Php2Html_TmpArray[0]] = $Php2Html_TmpArray[1];

}

//echo '假静态：$_GET变量 ';

print_r($_GET);

// Array ( [id|1@action|2] => [id] => 1 [action] => 2 ) echo " ";

echo "<hr>";

echo $_GET[id]." ";

// 1 echo $_GET[action];

// 2

?>

　　伪静态方法二：

<?php
//伪静态方法二

// localhost/php100/test.php/1/2

$filename = basename($_SERVER['SCRIPT_NAME']);

echo $_SERVER['SCRIPT_NAME']." ";// /php100/test.php

echo $filename." ";// test.php

if(strtolower($filename)=='test.php'){

if(!empty($_GET[id])){

$id=intval($_GET[id]);

echo $id." ";

$action=intval($_GET[action]);

echo $action." ";

}else{

$nav=$_SERVER['REQUEST_URI'];

echo "1:".$nav." ";// /php100/test.php/1/2

$script=$_SERVER['SCRIPT_NAME'];

echo "2:".$script." ";// /php100/test.php

$nav=ereg_replace("^$script","",urldecode($nav));

echo $nav." "; // /1/2

$vars=explode("/",$nav);

print_r($vars);// Array ( [0] => [1] => 1 [2] => 2 )

echo " ";

$id=intval($vars[1]);

$action=intval($vars[2]);

}

echo $id.'&'.$action;
}
?>

　　伪静态方法三：

<?php
//伪静态方法三

function mod_rewrite(){

global $_GET;

$nav=$_SERVER["REQUEST_URI"];

echo $nav." ";

$script_name=$_SERVER["SCRIPT_NAME"];

echo $script_name." ";

$nav=substr(ereg_replace("^$script_name","",urldecode($nav)),1);

echo $nav." ";

$nav=preg_replace("/^.ht(m){1}(l){0,1}$/","",$nav);//这句是去掉尾部的.html或.htm

echo $nav." ";

$vars = explode("/",$nav);

print_r($vars);

echo " ";

for($i=0;$i<Count($vars);$i+=2){

$_GET["$vars[$i]"]=$vars[$i+1];

}

return $_GET;

}

mod_rewrite();

$year=$_GET["year"];//结果为'2006'

echo $year." ";

$action=$_GET["action"];//结果为'_add'

echo $action;

?>

　　伪静态方法四：

<?php
//伪静态方法四

//利用server变量取得PATH_INFO信息该例中为 /1,100,8630.html 也就是执行脚本名后面的部分

if(@$path_info =$_SERVER["PATH_INFO"]){

//正则匹配一下参数

if(preg_match("/\/(\d+),(\d+),(\d+)\.html/si",$path_info,$arr_path)){

$gid=intval($arr_path[1]); //取得值 1

$sid=intval($arr_path[2]); //取得值100

$softid=intval($arr_path[3]); //取得值8630

}else die("Path:Error!");

//相当于soft.php?gid=1&sid=100&softid=8630

}else die('Path:Nothing!');

?>
