is there a way to remove all the non-existing indexes from a php array and then rearrange it? For example

Array
(
    [0] => a
    [2] => b
    [3] => c
    [6] => d
)

TO

Array
(
    [0] => a
    [开发者_Go百科1] => b
    [2] => c
    [3] => d
)

Big thanks! Rik.

Just use this built-in function

$array=array_values($array)

Use array_values.

$arr = array_values($arr);
