Want to delete array

Question

Can anyone help me to improve this code? I want to delete array if it already exists. Thanks

if(count($cart['Item']) > 0) {
    unset($cart['Item']);

    $items['Item'] = array();
    $cart = array_merge($cart, $items);
}

Do you want to delete the array if it exists or empty it if it has content? — iAndr0idOs

Apparently you want the $cart['Item'] variable to be an empty array after this step, no matter what it was before. So:

$cart['Item'] = array();

Done.

if(!empty($cart['Item'])) {
    unset($cart['Item']);
}

!empty requires the array item to be both existent and not falsy (e.g. empty)
unset will delete the given key from $cart

However, if you want to replace it with a new, empty array:

$cart['Item'] = array();

No need to do anything else. PHP has a Garbage Collector.

If you just need to check if it exists. using isset() is faster in your case. Then you can just override it without any unsetting.

if( isset($cart['Item']))
{   
    $cart['Item'] = array();
}

you can try this,

if(isset($cart['Item']) && !empty($cart['Item'])) {
    unset($cart['Item']);

}else{
    $items['Item'] = array();
    $cart = array_merge($cart, $items);
 }

Thanks.
