篇文章主要介绍了PHP实现炸金花游戏比赛的方法,实例分析了炸金花游戏的实现原理与相关算法技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了PHP实现炸金花游戏比赛的方法。具体分析如下:

程序离不开算法,前面讨论过寻路的算法。不过,当时的示例图中,可选的路径是唯一的。我们挑选一个算法,就是说要把这个唯一的路径选出来,怎么选呢?

炸金花两副牌的比较规则就不说了,注明一下是顺子的时候 : JQK < A23 < QKA

思路:炸金花

1. 随机生成两幅牌,每副牌结构为

代码如下:

array(      array('Spade','K'),      array('Club','6'),      array('Spade','J'),  )

代码如下:

array(      array('Spade','K'),      array('Club','6'),      array('Spade','J'),  )

2. 计算每副牌的分值:

每副牌有个原始大小(即排除对子,顺子,金花,顺金,筒子的大小),再

每张牌的分值为一个2位数,不足2位的补前导0,例如'A':14,‘10':10,'2‘:'02‘,'k‘:13,'7‘:07

将3张牌按点数大小排序(从大到小),凑成一个6位数。例如'A27':140702,‘829':090802,‘JK8':131108,‘2A10':141002

例外,对于对子要将对子的位数放在前两位(后面会看到为什么这么做)。例如‘779':070709,‘7A7':070714,‘A33':030314

现在的分值是一个6位数,将对子设为一个原始值加上10*100000的值,现在为一个7位数。例如‘779':1070709,‘7A7':1070714,‘A33':1030314

对于顺子,将结果加上20*100000.。例如‘345':2050403,‘QKA':2141312,‘23A':2140302

对于金花,将结果加上30*100000。例如‘Spade K,Spade 6,Spade J':3131106

因为顺金的时候其实是金花和顺子的和,所以顺金应该是50*10000。 例如‘Spade 7,Spade 6,Spade 8':5080706

对于筒子,将结果加上60*100000。例如'666‘:6060606,'JJJ‘:6111111

3. 比较两幅牌的大小(用所计算的分值来比较)

就这么简单!!

代码如下:

<?php  
    class PlayCards  
{     
    public $suits = array('Spade', 'Heart', 'Diamond', 'Club');      
    public $figures = array('2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A');      
    public $cards = array();      
    public function __construct()     
    {         
        $cards = array();          
        foreach($this->suits as $suit)
        {              
            foreach($this->figures as $figure)
            {                  
                $cards[] = array($suit,$figure);             
            }          
        }         
        $this->cards = $cards;      
    }      
    public function getCard()      
    {         
        shuffle($this->cards);          //生成3张牌         
        return array(array_pop($this->cards), array_pop($this->cards), array_pop($this->cards));         
    }     
    public function compareCards($card1,$card2)

        if($score1 > $score2) 
            return 1;         
        elseif($score1 < $score2) 
            return -1;         
        return 0;

            $figure[] = array_search($v[1],$this->figures)+2;        
        }          //补齐前导0          
        for($i = 0; $i < 3; $i++)
