介绍PHP5的给类型函数应用

<?php
// Dice Simulator
function roll_dice($number, $sides, $values = false) {
	// Loop as much as needed filling an array with the random die rolls.
	$dice = array();
	for ($i = 0; $i < $number; $i++) {
		$dice[] = rand(1, $sides);
	}
	
	// If the optional 3rd parameter is set to true, return the dice array:
	if ($values) {
		return $dice;
	} else {
		// Otherwise, return the sum of the dice:
		return array_sum($dice);
	}
}

// Roll 3 six sided dice and echo their result (between 3 & 18)
$roll_3d6 = roll_dice(3, 6);
echo "<pre>Dice roll = {$roll_3d6}\n";

// Roll a 100 sided die, 10 times, and echo all the values:
$rm_stats = roll_dice(10, 100, true);
print_r($rm_stats);
echo '</pre>';
?>
