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：
<?php class 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>'.$res['rankName'].'</h2>';
其中img.php是使用php生成图片的文件，参数num是点数，然后输出相应点数的图片，代码如下：
<?php class imgDock { public function getImg($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~
