php实现的中秋博饼游戏之掷骰子并输出结果功能详解

本文实例讲述了php实现的中秋博饼游戏之掷骰子并输出结果功能。分享给大家供大家参考，具体如下：

前面讲述了php实现的中秋博饼游戏之绘制骰子图案功能，纯php实现，就要用php来生成图案，第一步就先绘制骰子图案。下面就是编码实现业务逻辑，具体代码如下：

<?phpclass roll{  private $_defRank = 'lk';  public function lottery()  {    $dice   = $this->rollDice();    $format  = $this->formatDice($dice);    $rank   = $this->getRank($format);    $rankName = $this->getName($rank);    return [      'dice'   => $dice,      //'format'  => $format,      'rank'   => $rank,      'rankName' => $rankName,    ];  }  /**   * 获取筛子排名结果   * @param $dice   * @return array   */  public function getRes($dice)  {    $format  = $this->formatDice($dice);    $rank   = $this->getRank($format);    $rankName = $this->getName($rank);    return [      'dice'   => $dice,      'format'  => $format,      'rank'   => $rank,      'rankName' => $rankName,    ];  }  /**   * 掷骰子   * @return array   */  public function rollDice()  {    $res = [];    for ($i = 0; $i < 6; $i++) {      $res[] = mt_rand(1, 6);    }    return $res;  }  /**   * 格式化掷骰子结果   * @param array $list   * @return array   */  public function formatDice($list = [])  {    $data = [];    if (count($list) != 6) {      return $data;    }    $data = [      1 => 0,      2 => 0,      3 => 0,      4 => 0,      5 => 0,      6 => 0,    ];    foreach ($list as $val) {      if (isset($data[$val])) {        $data[$val] += 1;      }    }    foreach ($data as $key => $val) {      if ($val == 0) {        unset($data[$key]);      }    }    return $data;  }  /**   * 判断筛子结果的大小   * @param $list   * @return int|string   */  public function getRank($list)  {    $ruleList = $this->_getRule();    $res   = $this->_defRank;    if (!empty($ruleList)) {      foreach ($ruleList as $rank => $rankRules) {        foreach ($rankRules as $rule) {          foreach ($rule as $dian => $num) {            if (isset($list[$dian])) {              if ($list[$dian] == $num) {                $res = $rank;              } else {                //规则中只要有一条不满足就跳出当前规则验证                $res = $this->_defRank;                break;              }            } else {              //规则中只要有一条不满足就跳出当前规则验证              $res = $this->_defRank;              break;            }          }          //有一条规则匹配，跳出循环，          if ($res != $this->_defRank) {            break;          }        }        //有一条规则匹配，跳出循环，        if ($res != $this->_defRank) {          break;        }      }    }    return $res;  }  /**   * 根据排序获取掷骰子结果名称   * @param int $rank   * @return array   */  public function getName($rank = NULL)  {    $list = [      'cjh'  => '状元插金花',      'lbh'  => '六杯红',      'bdj'  => '遍地锦',      'ww'  => '五王',      'wzdyx' => '五子带一秀',      'wzdk' => '五子登科',      'zy'  => '状元',      'by'  => '榜眼',      'sh'  => '三红',      'sj'  => '四进',      'eq'  => '二举',      'yx'  => '一秀',      'lk'  => '轮空',    ];    if (!empty($rank)) {      $rankName = '';      if (isset($list[$rank])) {        $rankName = $list[$rank];      }      return $rankName;    }    return $list;  }  /**   * 返回规则   * @return array   */  private function _getRule()  {    return [      'cjh'  => [        [2 => 2, 4 => 4]      ],      'lbh'  => [        [4 => 6]      ],      'bdj'  => [        [1 => 6],        [2 => 6],        [3 => 6],        [5 => 6],        [6 => 6],      ],      'ww'  => [        [4 => 5],      ],      'wzdyx' => [        [1 => 5, 4 => 1],        [2 => 5, 4 => 1],        [3 => 5, 4 => 1],        [5 => 5, 4 => 1],        [6 => 5, 4 => 1],      ],      'wzdk' => [        [1 => 5],        [2 => 5],        [3 => 5],        [5 => 5],        [6 => 5],      ],      'zy'  => [        [4 => 4]      ],      'by'  => [        [1 => 1, 2 => 1, 3 => 1, 4 => 1, 5 => 1, 6 => 1]      ],      'sh'  => [        [4 => 3]      ],      'sj'  => [        [1 => 4],        [2 => 4],        [3 => 4],        [5 => 4],        [6 => 4],      ],      'eq'  => [        [4 => 2]      ],      'yx'  => [        [4 => 1]      ],    ];  }}$roll = new roll();$res = $roll->lottery();echo '<h2>骰子点数：</h2>';echo '<p>';foreach($res['dice'] as $val){  echo '<img src="img.php?num='.$val.'" >';}echo '</p>';echo '<h2>结果：</h2>';echo '<h2 style="color:red;">'.$res['rankName'].'</h2>';
