Why does this `$_SESSION = $_POST` fail?

What am I missing here? This is my PHP file:

<?
session_start();

echo print_r($_SESSION);
echo "<br>";
echo print_r($_POST);

// Save input in session
$_SESSION = $_POST;
echo "test1";
?>

<br>
test2

This file is accessed from a form submit, and I'm sure the post data exists. The output is:

Array ( [login] => 1 ) 1
Array ( [name] => test [type] => test ) 1
test2

and it makes no sense to me. The session content and post content are printed without problems.

But the $_SESSION = $_POST; appears to fail, and the rest of the script until the ?> doesn't give any response, which is obvious because the test1 text isn't printed.

I can't find out what happens with the $_SESSION = $_POST;. All questions I find on SO and elsewhere gives this way to store post data in the session.

I'm aware that session_start(); is needed prior to any output. Is there something else that is also needed in this case?

What am I missing?

Update - Test file

The exact code of a full test file (link removed) is:

<?
session_start();
?>

<html>
<head>

</head>
<body>

<?

echo print_r($_SESSION);
echo "<br>";
echo print_r($_POST);

// Save input in session
$_SESSION = $_POST;
echo "test1";
?>

<p>test2</p>

<form method="post" action="test.php">
    Type something to test: <input type="text" name="testfield" id="testfield">
    <input type="submit" value="Submit">
</form>

</body>
</html>

Update - Solved?

Okay, it is solved now. But this is STRANGE...

The problem appearently is caused by the comment. The // stops the script from running within the <?..?> brackets. When I remove the comment // Save input in session, then it works...?

Now WHAT am I missing here? It must be some php setting or something. Or maybe some file or script data that was changed. I guess that since @CodeCaster had it working, something happens on my PC that does it... But comments work anywhere else? Has anyone seen this before?

Working with Xampp, that example works just fine. The 'test1' is printed on the before and after a successful post. Using PHP 5.3.8.

Tested on Linux with PHP 5.3.6, also works fine printing the 'test1' in both cases.

So, it seems PHP is not the problem here.

i would instead foreach the $_POST and add it to $_SESSION['mypostvars']. Keep in mind that you should validate and verify the $_POST before storing them.

this is a possible duplicated of PHP merge $_POST into $_SESSION

Have you tried using $_SESSION['name'] = $_POST['name']; instead?

I've never used $_SESSION = $_POST;, and neither never seen it, in the whole time I programmed on PHP.

Hope this helps.
