(Well, at least it's tricky for me... :-) I need to sort an array based on three numbers that are situated in the middle of each array element. For example: $list[] is an array, and contains the following [unsorted] elements: Super-S862-030.jpg Super-S1162-040.jpg Super-S874-010.jpg Super-S1174-020.jpg I want to sort $list based on those last three numbers, just before the extension, so that the new sort order is: Super-S874-010.jpg Super-S1174-020.jpg Super-S862-030.jpg Super-S1162-040.jpg I tried writing my own sort function--but can't seem to get anywhere with it: function cmp ($a,$b) {

    if (substr($a,-5,2) == substr($b,-5,2)) return 0;
    return (substr($a,-5,2) < substr($b,-5,2)) ? -1 : 1 ;
    }

usort($list,"cmp"); Any ideas? (Thanks.) ...Rene --- René Fournier, rene@smartslitters.com Toll-free +1.888.886.2754 Tel +1.403.291.3601 Fax +1.403.250.5228 www.smartslitters.com SmartSlitters International #33, 1339 - 40th Ave NE Calgary AB T2E 8N6 Canada
