    [bms] => Array
        (
            [0] => 123456_bms_for__on__(10-06-2015_18-57).pdf
        )

    [fr] => Array
        (
            [0] => 123456_fr_on_09-21-2015_(09-22-2015_11-46).pdf
        )

    [pcm] => Array
        (
            [0] => 123456_pcm_for_vignesh_on__(10-12-2015_12-30).pdf

if you have predefined above keys which will not increase in future you can think about reconstructing the array. — siddhesh

You can use uksort like as

$pos = ['bms', 'dr', 'fds', 'pcm', 'fr'];
uksort($arr, function ($a, $b) use ($pos) {
    foreach ($pos as $value) {
        if ($value == $a) {
            return 0;
            break;
        }
        if ($value == $b) {
            return 1;
            break;
        }
    }
});

You can use uksort PHP function.

uksort() will sort the keys of an array using a user-supplied comparison function. If the array you wish to sort needs to be sorted by some non-trivial criteria, you should use this function.

$sortOrder = array("bms", "dr", "fds", "pcm", "fr");

uksort($yourArray, function($a, $b) use ($sortOrder) {
    return array_search($a, $sortOrder) - array_search($b, $sortOrder); 
});

Working IDEOne or eval.in demos.
