// of the numbers by using the for loop

// It's the size of butterfly pattern
$h = 7;

echo "-----This the butterfly pattern-----\n\n";

// This will print the butterfly pattern
butterflyPattern($h);

// It's the function to

function butterflyPattern($h) {
	for($r = 1; $r <= $h - 1; $r++) {
        echo "\t";
        for($d = 1; $d <= $r; $d++)
            echo $d . " ";
        for($s = 1; $s <= 2 * ($h - $r); $s++)
            echo "  ";
        for($d = $r; $d >= 1; $d--)
            echo $d . " ";

            echo $d . " ";
        echo "\n";
    }
}

?>
