Merry Christmas to all my readers.

Merry Christmas!

ConPHPigurable Tree:
$rows = array(1,3,5,7,9,11,13,15,17,20,25,31,2,2,2);
$cp = $rows;
sort($cp);
$wi = $cp[count($cp)-1];
$char = “*”;
foreach ($rows as $c) {
$buff = round(($wi-$c)/2);
print str_repeat ( ” ” , $buff );
print str_repeat ( $char , $c );
print “\n”;
}
