Can't keep my variables from one php page to another

I can't keep my variables from one php page to another despite i use the session_start and $_SESSION functions. Can't anyone help me?

Show the smallest and simplest PHP script that illustrates this problem.

In page nº1 i use

session_start();
$_SESSION['user'] = $user;
header("Location: page2.php");

in page number 2
i use

$_RESQUEST[user] and it comes empty

you should access the store variable like:

$_SESSION['user']

It will not be in the $_REQUEST super global this is for passed form variables and cookies.

i used in page1.php

if($password != $pass2){
echo "Password incorrecta";
exit;
}
else
if($password == $pass2){
session_start();
$_SESSION[user] = $user;
header("Location:page2.php");
}

in page2.php i have the following

$user = $_SESSION[user];
echo $user;

it still comes empty. I'm begging to despair.

You may want to be careful how you address your array references.

If you are using:

$_SESSION[user]

and not

$_SESSION['user']

Array do's and don'ts
Why is $foo[bar] wrong?
You should always use quotes around a string literal array index. For example, use $foo['bar'] and not $foo[bar]. But why is $foo[bar] wrong? You might have seen the following syntax in old scripts:

<?php
$foo[bar] = 'enemy';
echo $foo[bar];
// etc
?>

This is wrong, but it works. Then, why is it wrong? The reason is that this code has an undefined constant (bar) rather than a string ('bar' - notice the quotes), and PHP may in future define constants which, unfortunately for your code, have the same name. It works because PHP automatically converts a bare string (an unquoted string which does not correspond to any known symbol) into a string which contains the bare string. For instance, if there is no defined constant named bar, then PHP will substitute in the string 'bar' and use that.
