PHP 伪静态隐藏传递参数名的四种方法

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。

 
<?php 
//伪静态方法一 
// localhost/php100/test.php?id|1@action|2 
$Php2Html_FileUrl = $_SERVER["REQUEST_URI"]; 
echo $Php2Html_FileUrl."<br>"; 
// /php100/test.php?id|1@action|2 
$Php2Html_UrlString = str_replace("?","",str_replace("/", "", strrchr(strrchr($Php2Html_FileUrl, "/"),"?"))); 
echo $Php2Html_UrlString."<br>"; 
// id|1@action|2 
$Php2Html_UrlQueryStrList = explode("@", $Php2Html_UrlString); 
print_r($Php2Html_UrlQueryStrList); 
// Array ( [0] => id|1 [1] => action|2 ) echo "<br>"; 
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 "<br>"; 
$_GET[$Php2Html_TmpArray[0]] = $Php2Html_TmpArray[1]; 
} 
//echo '假静态：$_GET变量<br />'; 
print_r($_GET); 
// Array ( [id|1@action|2] => [id] => 1 [action] => 2 ) echo "<br>"; 
echo "<hr>"; 
echo $_GET[id]."<br>"; 
// 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']."<br>";// /php100/test.php 
echo $filename."<br>";// test.php 
if(strtolower($filename)=='test.php'){ 
if(!empty($_GET[id])){ 
$id=intval($_GET[id]); 
echo $id."<br>"; 
$action=intval($_GET[action]); 
echo $action."<br>"; 
}else{ 
$nav=$_SERVER['REQUEST_URI']; 
echo "1:".$nav."<br>";// /php100/test.php/1/2 
$script=$_SERVER['SCRIPT_NAME']; 
echo "2:".$script."<br>";// /php100/test.php 
$nav=ereg_replace("^$script","",urldecode($nav)); 
echo $nav."<br>"; // /1/2 
$vars=explode("/",$nav); 
print_r($vars);// Array ( [0] => [1] => 1 [2] => 2 ) 
echo "<br>"; 
$id=intval($vars[1]); 
$action=intval($vars[2]); 
} 
echo $id.'&'.$action; 
} 
?> 

 
<?php 
//伪静态方法三 
function mod_rewrite(){ 
global $_GET; 
$nav=$_SERVER["REQUEST_URI"]; 
echo $nav."<br>"; 
$script_name=$_SERVER["SCRIPT_NAME"]; 
echo $script_name."<br>"; 
$nav=substr(ereg_replace("^$script_name","",urldecode($nav)),1); 
echo $nav."<br>"; 
$nav=preg_replace("/^.ht(m){1}(l){0,1}$/","",$nav);//这句是去掉尾部的.html或.htm 
echo $nav."<br>"; 
$vars = explode("/",$nav); 
print_r($vars); 
echo "<br>"; 
for($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."<br>"; 
$action=$_GET["action"];//结果为'_add' 
echo $action; 
?> 

 
<?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!'); 
?>
