php - Why session doesn't recognise manual change of cookie? -


i trying understand sessions, , conducted test:

my code is:

test.php

<? @session_start();  if(isset($_session['test'])) {  echo "test success";  } ?>

when enter cookie manually browser using addon as: 

phpsessid test

it not recognise it.

$_session "superglobal" (available everywhere) array tied cookie using unique session id.

if you're wanting reference cookie values you've set you'll need use $_cookie superglobal array.

you can read more superglobals here: http://php.net/manual/en/language.variables.superglobals.php

and how $_session , $_cookie works here: http://php.net/manual/en/reserved.variables.cookies.php http://php.net/manual/en/reserved.variables.session.php

you cannot set values in session using browser that. php place you'll able set 'test' key value, true or false.

session_start();  // assign based on value of cookie $_session['test'] = true;  if ($_session['test']) {     // test session }

hope helps.
