php - Finding and changing the value of a single "href" value using Simple Html DOM Library -


i need in parsing href attribute of single anchore tag , changing value in php file using "simple html dom" library. below html code:- 

<li id="toggle"> <a id="open" class="open" href="#" style="display: block; "></a></li>

now want specific href value , change page say, logout.php depending upon if user logged in or not. , here php code:

<?php      include 'simple_html_dom.php';     session_start();     $html = new simple_html_dom();     $html->load_file('index1.php');      if(!isset($_session['username'])){        $ret = $html->find('li[id=hello]');        $ret = "hello guest";        $tog = $html->find('li[id=toggle]');        $tog = "log in | register";      }else{          $user = $_session['username'];          $ret = "hello " . $user;          $tog = "log out";          $hrf = $html->find('a[id=open]');          $hrf->href = 'logout.php';       }   ?>

now except finding , changing "href" value, other things working properly. welcomed. in advance.

now able solve problem. think both of overlooked fact returning array. did solve. may 1 else also.

$e = $html->find('a[id=open]'); // returns array containing info anchor $link = $e[0]->href; //the value of attribute href of anchor first element       in array $e[0]->href = 'logout.php'; // new value $link = $e[0]->href; // assign value variable
