How to Remove Array Element and Then Re-Index Array?

$arr = array(1, 2, 3);

unset($arr[0]);

print_r($arr);

//Array ( [1] => 2 [2] => 3 )

What's the function called, so the output instead would be:

//Array ( [0] => 2 [1] => 3 )

You want to create a new array using array_values:

$arr = array(1, 2, 3);
unset($arr[0]);
$arr = array_values($arr);

print_r($arr);
//Array ( [0] => 2 [1] => 3 )
