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;">".$res["rankName"]."</h2>";其中img.php是使用php生成图片的文件，参数num是点数，然后输出相应点数的图片，代码如下：
<?phpclass imgDock{ public function getImg($num = 0) { if(!empty($num)){ header("Content-Type:image/png"); $img = imagecreatetruecolor(200, 200); $white = imagecolorallocate($img, 255, 255, 255); $grey = imagecolorallocate($img, 100, 100, 100); $blue = imagecolorallocate($img, 0, 102, 255); $red = imagecolorallocate($img, 255, 0, 0); imagefill($img, 0, 0, $white); imageline($img, 10, 20, 10, 180, $grey); imageline($img, 10, 180, 20, 190, $grey); imageline($img, 20, 190, 180, 190, $grey); imageline($img, 180, 190, 190, 180, $grey); imageline($img, 190, 180, 190, 20, $grey); imageline($img, 190, 20, 180, 10, $grey); imageline($img, 180, 10, 20, 10, $grey); imageline($img, 20, 10, 10, 20, $grey); //1/2/3/4/5/6 switch($num){ case 1: imagefilledarc($img, 100, 100, 50, 50, 0, 0, $blue, IMG_ARC_PIE); break; case 2: imagefilledarc($img, 60, 100, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 140, 100, 40, 40, 0, 0 , $red, IMG_ARC_PIE); break; case 3: imagefilledarc($img, 50, 50, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 100, 100, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 150, 150, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); break; case 4: imagefilledarc($img, 50, 50, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 50, 150, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 150, 150, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 150, 50, 40, 40, 0, 0 , $red, IMG_ARC_PIE); break; case 5: imagefilledarc($img, 50, 50, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 50, 150, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 100, 100, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 150, 150, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); imagefilledarc($img, 150, 50, 40, 40, 0, 0 , $blue, IMG_ARC_PIE); break; case 6: imagefilledarc($img, 50, 50, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 50, 150, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 100, 50, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 100, 150, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 150, 150, 40, 40, 0, 0 , $red, IMG_ARC_PIE); imagefilledarc($img, 150, 50, 40, 40, 0, 0 , $red, IMG_ARC_PIE); break; default: break; } imagepng($img); imagedestroy($img); } }}$num = 0;if(isset($_GET["num"])){ $num = intval($_GET["num"]);}$imgDock = new imgDock();$imgDock->getImg($num);下面是我抽中状元的效果图，O(∩_∩)O哈哈~
