What's better to use in PHP, $array[] = $value or array_push($array, $value)?

Question

What\'s better to use in PHP for appending an array member,

$array[] = $value;

or

array_push($array, $value);

Answer 1

Second one is a function call so generally it should be slower than using core array-access features. But I think even one database query within your script will outweight 1.000.000 calls to array_push().
