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 => \'

To add to the other answers, array_values() will not preserve string keys. If your array has a mix of string keys and numeric keys (which is probably an indication of bad design, but may happen nonetheless), you can use a function like:

function reset_numeric_keys($array = array(), $recurse = false) {
    $returnArray = array();
    foreach($array as $key => $value) {
        if($recurse && is_array($value)) {
            $value = reset_numeric_keys($value, true);
        }
        if(gettype($key) == 'integer') {
            $returnArray[] = $value;
        } else {
            $returnArray[$key] = $value;
        }
    }

    return $returnArray;
}
