While 循环仅显示数据库中的第一行

Question

我知道这是一个超级基本的问题，但我一整天都找不到答案。 我试图在一个表中显示我所有的数据库行，而我的 while 循环只显示第一行。

我尝试将 while 循环的条件更改为“mysqli_fetch_array”，然后甚至第一行都没有出现。

echo "<table>";
    echo "<tr>
        <th>Match_Id</th>
        <th>Home_Team</th> 
        <th>Away_Team</th>
        <th>Result</th>
        <th>season</th> 
        <th>notes</th>
        <th>Goals_Sum</th>
      </tr> ";


     $sql = "SELECT * FROM PremierLeague";
   `enter code here`  $result = sqlsrv_query($conn, $sql);

 while ($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)) {
     echo "<tr>";
     $id = $row['id'];
     echo "<td>$id</td>";
     $Home = $row['Home'];
     echo "<td>$Home</td>";
     $Away = $row['Away'];
     echo "<td>$Away</td>";
     $result = $row['result'];
     echo "<td>$result</td>";
     $season = $row['season'];
     echo "<td>$season</td>";
     $notes = $row['notes'];
     echo "<td>$notes</td>";
     $home_goals= $row['home_goals'];
     $away_goals= $row['away_goals'];
     $GoalSum = $home_goals+$away_goals;
     echo "<td>$GoalSum</td>";
     echo "</tr>";
 }
  echo "</table>";

预期结果：包含数据库中所有行的表。 实际结果：只有数据库的第一行

echo "<table>";
    echo "<tr>
        <th>Match_Id</th>
        <th>Home_Team</th> 
        <th>Away_Team</th>
        <th>Result</th>
        <th>season</th> 
        <th>notes</th>
        <th>Goals_Sum</th>
      </tr> ";


     $sql = "SELECT * FROM PremierLeague";
  $result = sqlsrv_query($conn, $sql);

 while ($row = sqlsrv_fetch_array($result, SQLSRV_FETCH_ASSOC)) {
            $id = $row['id'];
          $Home = $row['Home'];
          $Away = $row['Away'];     
        $result = $row['result'];
       $season = $row['season'];
       $notes = $row['notes'];
     $home_goals= $row['home_goals'];
     $away_goals= $row['away_goals'];
     $GoalSum = $home_goals+$away_goals;



 echo $output.="<tr>
                 <td>$id</td>
                 <td>$Home</td>
                 <td>$Away</td>
                 <td>$result</td>
                 <td>$season</td>
                 <td>$notes</td>
                 <td>$GoalSum</td>
                </tr>";
 }
  echo "</table>";

您的代码示例乍一看很干净，但这仍然让我想起两种不同的可能性：

• 您的表只包含一行。这很愚蠢，但必须先检查。好吧，我想你做到了；
• 一个无关的分号“;”在while() 条件后被遗忘：

    while($res=fetch(…));
    {
        display something…
    }

在这种情况下，循环将迭代直到数据集结束，然后将输入大括号中的块（假定为孤立块），显示变量中剩余的内容。但在这种情况下，您应该得到查询的最后行，而不是第一行。
