Php 使用json编码

我第一次尝试使用json编码，需要了解我做错了什么

应该是这样的：

{团队：[2147483647,9]，[2147483647,6]，[2147483647,4]，[11,2147483647]，[5,2147483647]，[12,8]，[10,3]，[2147483647,7]，]，结果：[[0,1]，[0,1]，[1,0]，[0,0]，[0,1]，[0,0]，[0,0]，[0,0]，[0,0]，[0,0]，[0,0]，[0,0]

但返回的数据如下所示：-

{小组：[[2147483647,10,5,12,11214748364721474836472147483647]，[7,32147483647,82147483647,4,6,9]，[0,0,0,0,0,0,0,0]，[0,0,0,0,0,0,0,0,0]]

代码：

在显示团队的地方，应该每两个团队关闭一个括号]？

希望有人能帮忙。

不要说这会解决您的问题，但它可能会帮助您理解PHP

class mustBeAClass{
  protected function max($tnid){
    // must have this function - can be public for outside method use
  }
  protected function tourn_info($typ, $tnid){
    // must have this function - can be public for outside method use
  }
  protected function getname($arg0, $arg1, $arg2, $arg3, $arg4, $arg5, $arg6 = 0){
    /* must have this function - can be public for outside method use
    notice that $arg6 is how you assign default to arguments */
  }
  public function getAutoCompleteData($tournID, $db){
    $db->open();
    $max = $this->max($tournID); $one = $this->tourn_info("1on1", $tournID);
    // what is the point of this ---->>>> $total_matches = $max;
    $after_matches = $max / 2;
    // notice query issue below
    $matches = $db->query("SELECT * FROM matches WHERE leagueID ='$tournID' && league='tourn'"));
    // while loop has problems
    if($matches->num_rows < 1){
      die('You have no matches');
    }
    else{
      while($row = $db->fetch_assoc()){
        $clan1 = $this->getname($row['clan1'], $tournID, 'tourn', null, 1, 1, 0);
        $clan2 = $this->getname($row['clan2'], $tournID, 'tourn', null, 1, 1, 1);
        if($row['matchno'] <= $after_matches) {
          $clan_one[]  = $row['clan1'];
          $clan_two[]  = $row['clan2'];
          $score_one[] = $row['score1'];
          $score_two[] = $row['score2'];
        }
      }
      $data = array(
        'teams' => array($clan_one, $clan_two),
        'results' => array($score_one, $score_two)
      );
    }
    $matches->free(); $db->close();
    return $data;
  }
}
$cls = new mustBeAClass; 
echo json_encode($cls->getAutoCompleteData($tournId, $db));

当然，要为$tournId使用正确的值，为$db使用新的mysqli/*args*/值。

但是第一个代码不是JSON……您的类在哪里$这是指一个类。使构造函数在类中使用公共函数{}。您的代码非常混乱。变量$1、$clan1、$clan2从不使用。您正在创建一个包含两个项的数组，每个项包含两个项。您的JSON显示的内容正是如此。您是否尝试过使用JSON_encode函数？我会假设它是您的数据库输出，或者按照以下方式处理您的数据库输出，从而创建意外的输出。json_encode只是将PHP数组像json一样绘制出来。似乎您还得到了意外的新数字，等等，所以我将尝试使用var_dump打印数据库内容，并查看到底发生了什么。
