Re: can I do a for each here??

[Jeff Schmidt <jschmid@xxxxxxxxxx>]

Yeah, after hitting the send button, I looked again at what I sent and 
realized something else. Having already caused PHP to put the stuff into 
an array, by the way I suggested constructing the form, you can 
eliminate the foreach loop, and just use the assignment operator to get 
PHP to copy the array from $_POST to $_SESSION (although, you might want 
to do some validation code, in which case you probably do want to use 
the foreach block, so that you have a chance to validate each of the 
submitted values, and the keys [sometimes it's usefull to validate the 
keys, to check to see if someone has forged a form submission with 
values other than what they are supposed to be using]).

But, assuming you aren't worried about validating, you could do like this:

$_SESSION['age'] = $_POST['age'];

But, honestly, I would still use the foreach loop, check the values of 
$name and $age to make sure they are legal, and in the correct format, 
and then assign them individually, as before.
