Problem adding value to session array

I have a session array that stores some values that I set. It holds all the inserted values, unless the value I want to insert has a space in it, then it only inserts the characters before the space into the array. It looks like this: // This works $sessionArray[1] = "nospace"; echo "result: ".$sessionArray[1]; // result: nospace // This doesn't work $sessionArray[1] = "with space"; echo "result: ".$sessionArray[1]; // result: with // should be result: with space Anyone know how to fix or avoid this from happening? Thanks, Matt
