Function with Returns

[moracom]

I'm having problems with one of my functions.
This is my first function:

function test1()
$configuration = "mint";
return $configuration;
}

The result of this function will be: "mint" and that's exactly what i'm looking for.

The second function is:

function test2()
$abc = "mint";
$configuration = $abc;
return $configuration;
}

Again the result of this function will be: "mint" and that's exactly what i'm looking for.

Now here's my problem with my third function:

function test3()
$configuration = $_SESSION['MyWord'];
return $configuration;
}

I dont get any results. Am I not able to return session variable?
Thanks in advance for your help.

you have a typo

function test3() {

but

<?php
session_start();

$_SESSION['MyWord'] = "mint";

function test3() {
	$configuration = $_SESSION['MyWord'];
	return $configuration;
}

echo test3();
?>

worked fine for me
