(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.)
