Check out http_build_query

example

<?php
$arr = array(1,2,3,4);
echo http_build_query(array('arr'=>$arr));
//arr%5B0%5D=1&arr%5B1%5D=2&arr%5B2%5D=3&arr%5B3%5D=4

You can serialize it easily, then unserialize it to get it back to an array:

$result=serialize(Users.LoggedInUsers());
header('Location: http://localhost/Campus/Users.php?id='.$result.'');

If you unserialize untrusted input from a URL, be certain to validate the entire contents of the array.

It is showing following error Warning: Header may not contain more than a single header, new line detected on Users.php i did $booksArr = $_GET['id']; $result=unserialize(urldecode($booksArr));
