    $keys =  array('12_01','01_02','02_03','03_04','04_05','05_06','06_07','07_08','08_09','09_10','10_11','11_12');
    $result = array();
    foreach($keys as $value){
        $val = explode('_',$value);

        $result[$value] = $val[0].':00 - '.$val[1].':00';

    }
    echo '<pre>';print_r($result);exit;

You can try with this code. You will getting result in result array.

Use ksort():

$hourshow = array(...);
ksort($hourshow);
// $hourshow is now sorted according to key.

Dont know if I get your question correctly, but this should be what you are looking for array_intersect_key($hourshow, array_flip($yourWantedHoursArray));

@Ashish Vyas Simply do it like below

<?php
    $youKeysFetchedFromDb = array("12_01", "01_02"); //suppose

    foreach($youKeysFetchedFromDb as $value){
        echo $hourshow[$value];
    }
