[Resolved] need help in sorting arrays

Fking

I have two arrays
one with the name of the images in a directory

Array ( [0] => 1.jpg [1] => 10.jpg [2] => 11.jpg [3] => 12.jpg [4] => 13.jpg [5] => 14.jpg [6] => 15.jpg [7] => 16.jpg [8] => 17.jpg [9] => 18.jpg [10] => 19.jpg [11] => 2.jpg [12] => 20.jpg [13] => 21.jpg [14] => 22.jpg [15] => 23.jpg [16] => 24.jpg [17] => 25.jpg [18] => 26.jpg [19] => 27.jpg [20] => 28.jpg [21] => 29.jpg [22] => 3.jpg [23] => 30.jpg [24] => 31.jpg [25] => 32.jpg [26] => 33.jpg [27] => 34.jpg [28] => 35.jpg [29] => 36.jpg [30] => 37.jpg [31] => 38.jpg [32] => 39.jpg [33] => 4.jpg [34] => 40.jpg [35] => 41.jpg [36] => 42.jpg [37] => 43.jpg [38] => 44.jpg [39] => 45.jpg [40] => 46.jpg [41] => 47.jpg [42] => 48.jpg [43] => 5.jpg [44] => 6.jpg [45] => 7.jpg [46] => 8.jpg [47] => 9.jpg )

and one with the name of the thumbs in the same directory

Array ( [0] => th_10jpg.jpg [1] => th_11jpg.jpg [2] => th_12jpg.jpg [3] => th_13jpg.jpg [4] => th_14jpg.jpg [5] => th_15jpg.jpg [6] => th_16jpg.jpg [7] => th_17jpg.jpg [8] => th_18jpg.jpg [9] => th_19jpg.jpg [10] => th_1jpg.jpg [11] => th_20jpg.jpg [12] => th_21jpg.jpg [13] => th_22jpg.jpg [14] => th_23jpg.jpg [15] => th_24jpg.jpg [16] => th_25jpg.jpg [17] => th_26jpg.jpg [18] => th_27jpg.jpg [19] => th_28jpg.jpg [20] => th_29jpg.jpg [21] => th_2jpg.jpg [22] => th_30jpg.jpg [23] => th_31jpg.jpg [24] => th_32jpg.jpg [25] => th_33jpg.jpg [26] => th_34jpg.jpg [27] => th_35jpg.jpg [28] => th_36jpg.jpg [29] => th_37jpg.jpg [30] => th_38jpg.jpg [31] => th_39jpg.jpg [32] => th_3jpg.jpg [33] => th_40jpg.jpg [34] => th_41jpg.jpg [35] => th_42jpg.jpg [36] => th_43jpg.jpg [37] => th_44jpg.jpg [38] => th_45jpg.jpg [39] => th_46jpg.jpg [40] => th_47jpg.jpg [41] => th_48jpg.jpg [42] => th_4jpg.jpg [43] => th_5jpg.jpg [44] => th_6jpg.jpg [45] => th_7jpg.jpg [46] => th_8jpg.jpg [47] => th_9jpg.jpg )

as u can see they do not match
i mean that in some of the cases, the values behind the same key in both arrays, are different
how to sort them in a way that it places them in the same order in both arrays?

also it will be good if i also can sort them like that
1.jpg, 2.jpg and so on
and not as it is now, 1.jpg, 10.jpg and so on

You mean like you get with [man]natsort[/man]?

exactly!

that's the exact function, how i haven't found it...

Just a suggestion--I've found that giving each file the same amount of digits in the number makes for easier sorting, easier-to-read listings, better file listing, etc., and I'd remove the extraneous "jpg" for easier matching. This one-time routine will do that, and allow for up to 999 files (change the 7 to an 8 for up to 9999 files, of course):

$arr_1 = array ('10.jpg', '11.jpg', 
                '1.jpg', '2.jpg'); // etc.
$arr_2 = array ('th_10jpg.jpg', 'th_11jpg.jpg', 
                'th_1jpg.jpg', 'th_2jpg.jpg'); // etc.

foreach ($arr_1 as $key => $value) {
    $len = strlen($value);
    if ($len < 7) {
        for ($i = 0; $i < (7 - $len); $i ++) {
            $arr_1[$key] = '0' . $arr_1[$key];
        }
    }
    rename('dir/' . $value, 'dir/' . $arr_1[$key]);
    echo $arr_1[$key] . '<br />';
} 
foreach ($arr_2 as $key => $value) {
    $arr_2[$key] = str_replace('jpg.', '.', $value);
    $arr_2[$key] = str_replace('th_', '', $arr_2[$key]);
    $len = strlen($arr_2[$key]);
    if ($len < 7) {
        for ($i = 0; $i < (7 - $len); $i ++) {
            $arr_2[$key] = '0' . $arr_2[$key];
        }
    }
    $arr_2[$key] = 'th_' . $arr_2[$key];
    rename('dir/' . $value, 'dir/' . $arr_2[$key]);
    echo $arr_2[$key] . '<br />';
}

It's not real efficient coding, but you'd need to use it only once. (I'd comment out the "rename()" lines first to see that it works right; it does for me.)
