Sort a flat array by its keys

Question

How do I order an array by key, this is example:

array(3){
    [3] => array(),
    [2] => array(),
    [1] => array()
}

What I need is:

array(3){
    [1] => array(),
    [2] => array(),
    [3] => array()
}

I didn't understand the question. Can you please elaborate on your example? — MeLight

Please fix the type of the last element key, which should be 3 (I guess?) — ajreal

ksort

Sorts an array by key, maintaining key to data correlations. This is useful mainly for associative arrays.

Your what I need doesn't make sense, do you really want to kick out [3] ? Other than that, to answer your actual question, to sort arrays by key, just use phps ksort
