Array problem.. surely this is simple..??

[richblend]

yo. making a shopping cart, using sessions to remember the contents, and storing the products in an array $cart[]. im making a thing so people can remov items from teh cart. problem is this.

it ends up as having an array like this....

$cart[0]="lamp";
$cart[1]="toothbrush";
$cart[2]="mug";
$cart[3]="pair or scissors";

etc...

so when they remove an item, it unsets that item. say they dont want the mug anymore, it removes it, but then im left with this:

$cart[0]="lamp";
$cart[1]="toothbrush";
$cart[3]="pair or scissors";

when really i want this...

$cart[0]="lamp";
$cart[1]="toothbrush";
$cart[2]="pair or scissors";

So how can i force the index numbers to be sequential again? i cant find an array function that does this....

any helps would be cool. cheers

You could flip through the array, and reassign everything, but this time, without gaps:

function stop_gap($array) {
    $newArray = array();
    foreach ($array as $value) {
        $newArray[] = $value;
    }
    return $newArray;
}
//call this function like this:
$items = stop_gap($items);

Alternatively, because knowing what items people cancel is a good thing to know - you might find that your mug is just too expensive, or people are giving it bad reviews; info you can use to improve your products - you could change the cancelled element to have a value of 'cancelled' or the empty string, (or whatever) instead of deleting it entirely . Then, while you're looping through the array, if it's empty or == 'cancelled' (or whatever), just skip to the next element.
