Bagaimana untuk menyembunyikan parameter yang diluluskan dalam php

<?php
//伪静态方法一

$Php2Html_FileUrl = $_SERVER["REQUEST_URI"];
echo $Php2Html_FileUrl."<br>";

// 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]] = $Php2Html_TmpArray[1];
}
//echo &#39;假静态：$_GET变量<br />&#39;;
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
?>

<?php
//伪静态方法二
// localhost/php100/test.php/1/2
$filename = basename($_SERVER[&#39;SCRIPT_NAME&#39;]);
echo $_SERVER[&#39;SCRIPT_NAME&#39;]."<br>";// /php100/test.php

<?php
//伪静态方法三
function mod_rewrite(){

echo $year."<br>";

?>

<?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(&#39;Path:Nothing!&#39;);
