如何用用户名添加计数？

Question

大家好，我正在列出类似Service的水龙头列表

现在我只是想知道如何显示用户名以及创建的和最近更新的列表，以及基于用户名的水龙头总数

我得到了一张我喜欢的照片，但是我不知道如何使它起作用：/

我喜欢它看起来像什么

用户的数据库表

列表的数据库表

编码

<?php
     $sql = "SELECT * FROM list  ";
     $result = mysqli_query($link, $sql);
     if( $result )    
     while($user = mysqli_fetch_assoc($result)) {
    ?> 
           <table class="table table-striped" id="faucetlist" width="100%" cellspacing="0">
                <thead>
                <tr>
                <th><center>Faucetlist</center></th>    
                <th><center>Created</center></th>                          
                <th><center>Last updated</center></th>
                <th><center>faucets</center></th> 
                 </tr>
                </thead>                      
             <tr>             
            <td><center><?php echo $user["username"]; ?></center></td>   
             <td><center><?php echo date('l jS F Y' , strtotime($user['Published']));?></center></td>              
            <td><center><?php echo date('h:i A' , strtotime($user['last_update']));?> </center></td>   
             <td><center>FAUCETS COUNT GO HERE </center></td>   

              </table>                    
       <?php } ?>

更改您的查询并遵循此代码

<?php
         $sql = "SELECT list.*,count(username) as faucet  FROM list  GROUP BY username";
         $result = mysqli_query($link, $sql);
         if( $result )    
         while($user = mysqli_fetch_assoc($result)) {
        ?> 
               <table class="table table-striped" id="faucetlist" width="100%" cellspacing="0">
                    <thead>
                    <tr>
                    <th><center>Faucetlist</center></th>    
                    <th><center>Created</center></th>                          
                    <th><center>Last updated</center></th>
                    <th><center>faucets</center></th> 
                     </tr>
                    </thead>                      
                 <tr>             
                <td><center><?php echo $user["username"]; ?></center></td>   
                 <td><center><?php echo date('l jS F Y' , strtotime($user['Published']));?></center></td>              
                <td><center><?php echo date('h:i A' , strtotime($user['last_update']));?> </center></td>   
                 <td><center>FAUCETS COUNT GO HERE </center><?php echo $user['faucet'];   ?></td>   

                  </table>                    
           <?php } ?>
