Built-in PHP function to reset the indexes of an array?

Question

Example:

$arr = array(1 => 'Foo', 5 => 'Bar', 6 => 'Foobar');
/*... do some function so $arr now equals:
    array(0 => 'Foo', 1 => 'Bar', 2 => 'Foobar');
*/

Answer 1

Use array_values($arr). That will return a regular array of all the values (indexed numerically).

PHP docs for array_values

Answer 2

array_values($arr);
