Quick question: How can I delete in an array like this?

[justineaguas]

For example, I have a session array where I put values like this:

 

$_SESSION['cart'][] = array("qty" => $qty, "p_id" => $p_id);

 

How will I delete one element from this array?

You'll need to know the index of the $_SESSION['cart'] array that you're inserting into. Assuming it's, for example, 1, you can go about it like this:

 

unset($_SESSION['cart'][1]['qty']);

unset

Will foreach($array as $key => $value) work?

 

$_SESSION[cart][$key]['qty'] - Will this work? Will the whole element be deleted? Including the p_id and qty?

If you want to delete all the elements of $_SESSION['cart']:

 

foreach($_SESSION['cart'] as $key => $val) {
    unset($_SESSION['cart'][$key]);
}
