php login script Undefined variable: _session script

Question

i am trying to have a login script burt i have this error Undefined variable: _session see below the pages

//checklogin.php

Answer 1

It is $_SESSION not $_session you also need to add session_start() on top of the page

FROM PHP DOC

Variables in PHP are represented by a dollar sign followed by the name of the variable. The variable name is case-sensitive.

Answer 2

$_SESSION is to be written capitalized. In your code it is all lower case:

if(!$_session['name']= myusername){

change to (also add the $ to myusername):

if(!$_SESSION['name']= $myusername){
