copying a multidimensional array to $_SESSION

[Rob Tweed]

Probably a simple question but I can't find the answer anyway.

Specifically, is it possible to copy a multidimensional array into the
$_SESSION array - ie a deep clone of all keys and data?

I naively assumed that

$_SESSION["myArray"'] = $myArray ;

would work but it doesn't appear to work. Is there a single function
or assignment I can use, or would I need to use a "foreach" at every
level?

Example:
$_SESSION['string1'] = 'String1';
$_SESSION['string2'] = 'String2';
$_SESSION['array1'] = array(1,2,3,4,5);
$_SESSION['array2'] = array(11,12,13,14,15);
print_r($_SESSION);

Thanks Rajesh, but not quite what I wanted. Let me perhaps explain
what I need more fully:

Lets say I have a multidimensional array inside my PHP page, eg:

$myMDArray[$x]
$myMDArray[$x][$y]
$myMDArray[$x][$y][$z]

where $x, $y and $z may be many different values, and, as shown, there
may be data at various levels in the dimensional hierarchy.

How can I dump this complete array into $_SESSION, and then do the
reverse to recover it again in a later page?

Specifically, do I have to do it laboriously with "foreach" loops
through each level in $myMDArray, or can I use some simple merge
function or operator?

I don't see why you can't just say $_SESSION['myMDArray'] = $myMDArray;
However, if it really doesn't work you can always serialize()/unserialize()
the array before/after putting it in the $_SESSION superglobal.

Yes.

Your code is
$_SESSION['myArray'] = $myArray ;
I assume.

That should work and it works for me. There might be problems with this,
if register_globals is _on_. If register_globals is activated, then
change the name of the array index or the name of the variable:

$_SESSION['xmyArray'] = $myArray ;
or
$_SESSION['myArray'] = $xmyArray ;

The one thing I didn't see in your code sample was a call to
session_start() before any of the references to $_SESSION. This
should really be the first line in your application and might be your
problem.
