php - Logout function works on one server not on another? -


i have basic php logout file destroy session on user , log them out of account. php file works on server php 5.2.17 (000webhosting).

but doesn't work on server php 5.3.21, doesn't logout user.

this code:

<?php session_start();  session_destroy();  $_session = array(); if(!session_is_registered('id')){  $msg = "you logged out"; } else { $msg = "<h2>could not log out</h2>"; }  ?>  <html> <body> <?php echo "$msg"; ?><br> <p><a href="login.php">click here</a> return our home page </p> </body> </html>

does know whats causing issue?

i used on new server , still didn't work:

<?php session_start(); unset($_session['id']); session_destroy();  $_session = array(); if(!isset($_session['id'])){  $msg = "you logged out"; } else { $msg = "<h2>could not log out</h2>"; }  ?>  <html> <body> <?php echo "$msg"; ?><br> <p><a href="login.php">click here</a> return our home page </p> </body> </html>

and here have far:

<?php  error_reporting(e_all); ini_set('display_errors', '1'); ?> <?php session_start(); $_session[ 0 ] = "id"; session_destroy();  unset($_session['0']); if(!isset($_session['0'])){  $msg = "by clicking button below, agree logged out."; } else { $msg = "<h2>could not log out</h2>"; }  ?>

it strange have refresh members page once browser show users logged out. if don't page refresh, stay logged in!!!

session_is_registered() deprecated, instead try using this:

→ on page call session_register()

     session_start();      $_session[ 0 ] = "id"; // in place of session_register()

→ , on page use session_is_registered()

→ edit: includes refresh tag "macgyver fix" session bug

     session_start();      echo '<meta http-equiv="refresh" content="0">'; // auto-refresh       if( !isset( $_session[ 0 ] ) ) // in place of session_is_registered()      {            echo "you logged out";       }      else       {           echo "<h2>could not log out</h2>";      }

css - Make div keyboard-scrollable in jQuery Mobile? -

from can tell, although jquery-mobile-powered pages can contain divs overflow set scroll or auto, , these divs can scrolled one-screen bar or mouse wheel, cannot scrolled using arrow keys, page-up/page-down, or home/end. instead, official "page" div (with data-role="page") absorbs input. perhaps other divs can't acquire focus, i'm not sure. is there way around this? edit: jsfiddle of simple example: https://jsfiddle.net/qogz0shx/ <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script> <script src="https://ajax.googleapis.com/ajax/libs/jquerymobile/1.4.5/jquery.mobile.min.js"> </script> <link rel="stylesheet" href="https://code.jquery.com/mobile/1.4.5/jquery.mobile-1.4.5.css"/> <style> #outer { overflow:scroll; height: 50vh; width: 50vw; } #inner { height: 500vh; width: 500vw; } ...
