Hiya,
I changed your date_file_sort() function so it echos a few things
function date_file_sort($a, $b)
{
echo "$a - $b - ";
$a = strtotime($a);
$b = strtotime($b);
echo "$a - $b - ".date("d-M-Y", $a)." - ".date("d-M-Y", $b)."\n";
return strcmp($a, $b);
}
"interesting" results....
Here's an alterative to this function that works (might not be the best way
though??)
function date_file_sort($a, $b)
{
list($x, $y, $z) = explode("-", $a); $a = "$z-$y-$x";
list($x, $y, $z) = explode("-", $b); $b = "$z-$y-$x";
return -strcmp($a, $b);
}
HTH
