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：

<?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)
  {

    $rank   = $this->getRank($format);
    $rankName = $this->getName($rank);
    return [

$roll = new roll();
$res = $roll->lottery();
echo '<h2>骰子点数：</h2>';
echo '<p>';

  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：

<?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:

          break;
        case 5:

          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);
