Question

I’ve Googled it for two days, and tried looking at the PHP manual, and I still can’t remember that function that aligns the key values for PHP arrays.

All I’m looking for is the function that takes this:

Array
(
    [0] => 1
    [3] => 2
    [4] => 3
    [7] => 4
    [9] => 5
)

And converts it into this:

Array
(
    [0] => 1
    [1] => 2
    [2] => 3
    [3] => 4
    [4] => 5
)

Basically, the array is first sorted by key (their values attached to them stay with them), then all the keys are set to all the counting numbers, consecutively, without skipping any number (0,1,2,3,4,5,6,7,8,9…). I saw it being used with ksort() a few months ago, and can’t see to remember or find this elusive function.

Answer 1

Well, you see, this one is hard, because the general description on the PHP array functions page does not say that this function does what you’re looking for.

But you can sort the array using ksort(), and then use this: array_values() . From the page from the PHP manual:

array_values() returns all the values from the input array and indexes numerically the array.
