PHP adds elements to an array

There are two ways for PHP to add elements to an array:

array_push() , $arr[]

The first one:

$arr = array();
array_push($arr, e1, e2 ... en);

## The #array_push() function adds (push) one or more elements to the end of the first argument's array and returns the length of the new array.

This function is equivalent to calling $array[] = $value multiple times.

Second method:

$arr = array();
$arr[] = e1;
$arr[] = e2;
...
$arr[] = en;

The second method will be much faster than the first method
