基于php伪静态的实现方法解析

 <?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
 ?>

 <?php
 //伪静态方法二
 
 // localhost/php100/test.php/1/2

 $year=$_GET["year"];//结果为'2006'
 echo $year."<br>";

 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!');
