<? 

function BubbleSort($sort_array,$reverse) 
{ 
for ($i = 0; $i < sizeof($sort_array); $i++){ 
for ($j = $i + 1; $j < sizeof($sort_array); $j++){ 
if($reverse){ 
if ($sort_array[$i] < $sort_array[$j]){ 
$tmp = $sort_array[$i]; 
$sort_array[$i] = $sort_array[$j]; 
$sort_array[$j] = $tmp; 
} 
}else{ 
if ($sort_array[$i] > $sort_array[$j]){ 
$tmp = $sort_array[$i]; 
$sort_array[$i] = $sort_array[$j]; 
$sort_array[$j] = $tmp;

Use like this 

$array = array{10,65,32,41,1,99}; 
$sorted = BubbleSort($array,0);
