问题是它会显示所有电子邮件和电话图像，但我只想在表中有记录时才显示图像

Answer 1

不清楚您是要填写所有记录还是只填写有图标的记录，您可以检查如下字段:

<?php
    while ($row3 = mysqli_fetch_array($data)) { 
  ?>  
    <tr>
        <td><a class="" href="<?php echo ($row3['email'])?$row3['email']:''; ?>" target="_blank">
            <?php if($row3['email']!=''){ echo '<i class="icon-custom icon-sm rounded-x fa fa fa-envelope"></i>';
            }else{echo '';} ?></td>                                       
        <td><a class="" href="<?php echo ($row3['phone'])?$row3['phone']:''; ?>" target="_blank">
            <?php if($row3['email']!=''){ echo '<i class="icon-custom icon-sm rounded-x fa fa-phone"></i>'; }
            else{echo '';}</td>                                     
    </tr>                     
 <?php 
        } 
 ?>
