PHP 伪静态隐藏传递参数名的四种方法

<?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!');
?>
