php - Retrieving URL folder name from string -


i having slight trouble. wanting find top level folder , use variable.

for instance.

if have url: http://www.someurl.com/foldername/hello.php

i @ url , echo 'foldername'.

at present code strips things echos 'hello.php'.

<?php  // url string //  function curpageurl() { $pageurl = 'http'; if ($_server["https"] == "on") {$pageurl .= "s";} $pageurl .= "://"; if ($_server["server_port"] != "80") { $pageurl .= $_server["server_name"].":".$_server["server_port"].$_server["request_uri"]; } else { $pageurl .= $_server["server_name"].$_server["request_uri"]; } return $pageurl; }  // split string , folder//  function curpagename() { return substr($_server["script_name"],strrpos($_server["script_name"],"/")); }  // pass along results // $foldername = curpagename();  echo $foldername;  ?> 

          <?php               $a = "http://www.someurl.com/foldername/hello.php";              $b =  explode('/',$a);              //var_dump($b);           // got result  array(5) { [0]=> string(5) "http:" [1]=> string(0) "" [2]=>                  string(15) "www.someurl.com" [3]=> string(10) "foldername" [4]=> string(9) "hello.php" }

// or echo foldername store value array in variable

         $value = $b['3'];          echo $value // output foldername        ?>
