tl;dr

Here's how to add elements to an empty array in PHP:

First, create an empty array:

$cart = array();

To add elements to the array, you can use either the array_push() function or a for loop.

To use array_push(), simply pass the array and the elements you want to add as arguments:

array_push($cart, 13); array_push($cart, 14);

Or, you can use a for loop to add elements to the array:

for($i=0;$i<=5;$i++){ $cart[] = $i; }

Finally, you can print the array to check that the elements have been added:

echo "<pre>"; print_r($cart); echo "</pre>";
