I just wrote a little function for sort an array in reverse order WITHOUT pre-ordering the numbers
in it..
I hope, someone can use it. ;)
<?php
function rsort_rec($array)
{
if ( !is_array($array) ) return $array; # return original input when it's not an array
$c = count($array);
$c--;
$j = -1;
for ( $i = $c; $i > -1; $i-- )
{
$array_rec[] = $array[$i];
}
return $array_rec;
}
$input = array(167, 20, 100, 205);
print_r(rsort($input)); # printout reordered array with rsort()
# Output: Array ( [0] => 205 [1] => 167 [2] => 100 [3] => 20 )
print_r(rsort_rec($input)); # printout reordered array with rsort_rec()
# Output: Array ( [0] => 205 [1] => 100 [2] => 20 [3] => 167 )
?>
