如何从玩家手中删除重复的扑克牌？

Question

我试图向玩家交出五张牌并对其进行评分.我的得分程序似乎工作正常,但我遇到了不时被处理的重复卡问题.我尝试使用while循环来检查重复的卡片,但这看起来有点像hackish.我的代码如下.请记住,我绝对是新手,所以解决方案越简单越好!非常感谢.

// create suits array
$suits = array("996", "997", "998", "999");

// create faces array
$faces = array();
$faces[1] = "1";
$faces[2] = "2";
$faces[3] = "3";
$faces[4] = "4";
$faces[5] = "5";
$faces[6] = "6";
$faces[7] = "7";
$faces[8] = "8";
$faces[9] = "9";
$faces[10] = "10";
$faces[11] = "11";
$faces[12] = "12";
$faces[13] = "13";

// create player's hand 
$card = array();

for ($i = 0; $i < 5; $i++)
{   
    $face_value = shuffle($faces);
    $suit_value = shuffle($suits);
    $card[$i] = $faces[$face_value].$suits[$suit_value];

    $counter = 0;
    while ($counter < 100)
    {
        if (in_array($card[$i], $card))
        {
            $face_value = shuffle($faces);
            $suit_value = shuffle($suits);
            $card[$i] = $faces[$face_value].$suits[$suit_value];
        }
        $counter++;
    }

    print ("<img src=\"../images/4/$card[$i].gif\">");

}

简单地设置一个包含52个元素的数组可能更有效,每个卡一个.

$cards = range(0,51);
shuffle($cards);
$hand = array();
for ($i = 0; $i < 5; $i++)
{
  $hand[$i] = $cards[$i];
}

请注意,您可以$i通过执行操作简单地提取卡片的套装和等级

$suit = $hand[$i] % 4;
$rank = $hand[$i] / 4;

这样可以防止重复.

编辑:西装和等级被逆转.他们现在应该是正确的.
