PHP获取多维数组

我试图使用bind_result，在fetch将一组数据提取到一个二维数组中时，我已经在互联网上搜索解决方案，但它并没有按预期工作。我不确定调试几个小时后代码中出现了什么错误。如果有人能帮助发现盲点，我将不胜感激

情景：

我的表格如下：

tbl_team
teamname    id      name    gender
team1       1       John    Male
team1       2       Kelly   Female
team1       3       Chan    Male
team2       1       Jordan  Male
... etc

Team1 Members as below:
3 - Chan - Male
3 - Chan - Male
3 - Chan - Male

within FETCH:
Array([0]=>Array([id]=>1 [name]=>John [gender]=>Male))
Array([0]=>Array([id]=>2 [name]=>Kelly [gender]=>Female) [1]=>Array([id]=>2 [name]=>Kelly [gender]=>Female))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Function returned:
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))

<?php 
function queryteam ($team)
{
  $stmt = $mysqli->prepare("select id, name, gender from tbl_team where teamname = ?");
   if($stmt)
  {
     $stmt->bind_param('s',$team);
     $stmt->execute();
     $stmt->store_result();

     //change this part
     //$stmt->bind_result($team_member['id'],$team_member['name'],$team_member['gender']);
     $stmt->bind_result($id, $name, $gender);
     /*******/

     $team = array();
     while($stmt->fetch())
     {
       $team_member = array();
       $team_member['id'] = $id;
       $team_member['name'] = $name;
       $team_member['gender'] = $gender;
       //echo implode(" - ", $team_member)."<br>"; //debug purpose
       $team[] = $team_member;
     }
     $stmt->close();
     return $team;
  }
}
?>

我创建了一个基于teamname查询这些数据的函数

<?php 
function queryteam ($team)
{
  $stmt = $mysqli->prepare("select id, name, gender from tbl_team where teamname = ?");
   if($stmt)
  {
     $stmt->bind_param('s',$team);
     $stmt->execute();
     $stmt->store_result();
     $stmt->bind_result($team_member['id'],$team_member['name'],$team_member['gender']);
     $team = array();
     while($stmt->fetch())
     {
       //echo implode(" - ", $team_member)."<br>"; //debug purpose
       $team[] = $team_member;
     }
     $stmt->close();
     return $team;
  }
}
?>

但事实上，我得到的结果如下：

tbl_team
teamname    id      name    gender
team1       1       John    Male
team1       2       Kelly   Female
team1       3       Chan    Male
team2       1       Jordan  Male
... etc

Team1 Members as below:
3 - Chan - Male
3 - Chan - Male
3 - Chan - Male

within FETCH:
Array([0]=>Array([id]=>1 [name]=>John [gender]=>Male))
Array([0]=>Array([id]=>2 [name]=>Kelly [gender]=>Female) [1]=>Array([id]=>2 [name]=>Kelly [gender]=>Female))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Function returned:
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))

<?php 
function queryteam ($team)
{
  $stmt = $mysqli->prepare("select id, name, gender from tbl_team where teamname = ?");
   if($stmt)
  {
     $stmt->bind_param('s',$team);
     $stmt->execute();
     $stmt->store_result();

     //change this part
     //$stmt->bind_result($team_member['id'],$team_member['name'],$team_member['gender']);
     $stmt->bind_result($id, $name, $gender);
     /*******/

     $team = array();
     while($stmt->fetch())
     {
       $team_member = array();
       $team_member['id'] = $id;
       $team_member['name'] = $name;
       $team_member['gender'] = $gender;
       //echo implode(" - ", $team_member)."<br>"; //debug purpose
       $team[] = $team_member;
     }
     $stmt->close();
     return $team;
  }
}
?>

查询返回的结果是正确的，因为我在while（fetch）期间尝试回显，但问题是，在while内部，数组被最新的fetch结果覆盖

提前感谢所有的帮助

**编辑 我已经编辑了脚本，并按照Geo的评论进行了测试：

<?php 
  function queryteam ($team)
  {
    ....
       $team = array();
       while($stmt->fetch())
       {
         //echo implode(" - ", $team_member)."<br>"; //debug purpose
         $team[] = $team_member;
         echo "within FETCH: <br>";
         print_r($team); echo "<br>";
       }
       $stmt->close();
       return $team;
    }
  }
  $team_array = queryteam( "team1");
  echo "Function returned:<br>";
  print_r($team_array); echo "<br>";
  ?>

感谢Orangepill和evans_murithi

我从来没有想到这是由bind_结果引起的

修改如下：

tbl_team
teamname    id      name    gender
team1       1       John    Male
team1       2       Kelly   Female
team1       3       Chan    Male
team2       1       Jordan  Male
... etc

Team1 Members as below:
3 - Chan - Male
3 - Chan - Male
3 - Chan - Male

within FETCH:
Array([0]=>Array([id]=>1 [name]=>John [gender]=>Male))
Array([0]=>Array([id]=>2 [name]=>Kelly [gender]=>Female) [1]=>Array([id]=>2 [name]=>Kelly [gender]=>Female))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Function returned:
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))
Array([0]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [1]=>Array([id]=>3 [name]=>Chan [gender]=>Male) [2]=>Array([id]=>3 [name]=>Chan [gender]=>Male))

<?php 
function queryteam ($team)
{
  $stmt = $mysqli->prepare("select id, name, gender from tbl_team where teamname = ?");
   if($stmt)
  {
     $stmt->bind_param('s',$team);
     $stmt->execute();
     $stmt->store_result();

     //change this part
     //$stmt->bind_result($team_member['id'],$team_member['name'],$team_member['gender']);
     $stmt->bind_result($id, $name, $gender);
     /*******/

     $team = array();
     while($stmt->fetch())
     {
       $team_member = array();
       $team_member['id'] = $id;
       $team_member['name'] = $name;
       $team_member['gender'] = $gender;
       //echo implode(" - ", $team_member)."<br>"; //debug purpose
       $team[] = $team_member;
     }
     $stmt->close();
     return $team;
  }
}
?>

您确定它就是这么做的吗？您是否对数组进行了

打印\r

，以确保其中的数据符合预期？您好，返回的数组中有3行，其中3行被查询的最新获取覆盖。你能分享更多关于打印的细节吗？事实上，我对PHP还很陌生。谢谢你的帮助！所有三个数组元素都是对同一变量的引用。。使用fetch而不是bind results为每个迭代创建新数组。在

bind\u result（）

中，为每个结果使用不同的变量，例如

bind\u result（$id，$name，$gender）

Hi Orangepill，注意到，将尝试此方法。马上更新。
