Four ways to hide passed parameter names in PHP pseudo-static_PHP Tutorial

//Pseudo-static method one
// 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."
";
// 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 'False static: $_GET variable
';
print_r($_GET);
// Array ( [ id|1@action|2] => [id] => 1 [action] => 2 ) echo "
";
echo "

---

";
echo $ _GET[id]."
";
// 1 echo $_GET[action];
// 2
?>

Pseudo-static method two:
//Pseudo-static Method 2
// localhost/php100/test.php/1/2
$filename = basename($_SERVER['SCRIPT_NAME']);
echo $_SERVER['SCRIPT_NAME']."< br>";// /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."< br>"; // /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;
}
?>

//Pseudo-static method three
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);//This sentence It is .html or .htm with the tail removed
echo $nav."
";
$vars = explode("/",$nav);
print_r($vars);
echo "
";
for($i=0;$i$_GET["$vars[$i]"]= $vars[$i+1];
}
return $_GET;
}
mod_rewrite();
$year=$_GET["year"];//The result is' 2006'
echo $year."
";
$action=$_GET["action"];//The result is '_add'
echo $action;
?>

//Pseudo-static method four
//Use the server variable to obtain the PATH_INFO information. In this example, it is /1,100,8630.html, which is the part after the execution script name
if(@ $path_info =$_SERVER["PATH_INFO"]){
//Regular match parameters
if(preg_match("//(d+),(d+),(d+).html/si",$path_info ,$arr_path)){
$gid=intval($arr_path[1]); //Get the value 1
$sid=intval($arr_path[2]); //Get the value 100
$ softid=intval($arr_path[3]); //Get the value 8630
}else die("Path:Error!");
//Equivalent to soft.php?gid=1&sid=100&softid=8630
}else die('Path:Nothing!');
