How to add elements to an empty array in PHP?
Both array_push and the method you described will work.
$cart = array();$cart[] = 13;$cart[] = 14;// etc//Above is correct. but below one is for further understanding$cart = array();for($i=0;$i<=5;$i++){ $cart[] = $i; }echo "<pre>";print_r($cart);echo "</pre>";Is the same as:
<?php$cart = array();array_push($cart, 13);array_push($cart, 14);// Or $cart = array();array_push($cart, 13, 14);?>
It's better to not use array_push and just use what you suggested. The functions just add overhead.
//We don't need to define the array, but in many cases it's the best solution.$cart = array();//Automatic new integer key higher than the highest //existing integer key in the array, starts at 0.$cart[] = 13;$cart[] = 'text';//Numeric key$cart[4] = $object;//Text key (assoc)$cart['key'] = 'test';
