php - 如何将连续的图像数量限制为三个？

Question

我正在将数据库中的图像填充到表格中，如何将图像限制为每行三个？

<table border="0" align="center" height="25%" width="25%"  >
<tr><td align="center" width="50px"  bgcolor="#4b2d0e"><strong><font color="#FFFFFF">Friend List</font></strong></td></tr>
 <? foreach($Selected as $row)
 {   
     $value = $row['dPath'];
     $imgp =  base_url()."images"."/".$value;
 ?>
 <tr><td bgcolor="#999999">
 <strong ><?=$row['dFrindName'].'</br>';?></strong>
 <? if($value!="") { ?>
 <a class="Tab_Link" href="<? echo site_url();?>/friends/View_FProfile/<?=$row['dMember_Id']?>"><img src="<?=$imgp ?>" name="b1" width="90" height="80" border="0"/></a><br>
 <? } else { ?>
 <a class="Tab_Link" href="<? echo site_url();?>/friends/View_FProfile/<?=$row['dMember_Id']?>"><img src="../images/us.png" width="90px" height="80px"></a>
 <? }?>
 </td></tr>
 <? }}?>
</table>

<?php 

$x=0;

    foreach($Selected as $row){

        if($x%3 == 0)
            echo '<tr>';

        $value = $row['dPath'];
        $imgp =  base_url()."images"."/".$value;
?>

        <td style="background-color:#999999;">
            <strong ><?=$row['dFrindName'].'</br>';?></strong>

            <?php if($value!="") {?>
                <a class="Tab_Link" href="<? echo site_url();?>/friends/View_FProfile/<?=$row['dMember_Id']?>"><img src="<?=$imgp ?>" name="b1" width="90" height="80" border="0"/></a><br>
            <?php } else { ?>
                <a class="Tab_Link" href="<? echo site_url();?>/friends/View_FProfile/<?=$row['dMember_Id']?>"><img src="../images/us.png" width="90px" height="80px"></a>
            <?php }?>
        </td>
<?php
        if($x%3 == 0)
            echo '</tr>';
        x++; 
    }

    if(($x-1)%3 != 0)
        echo '</tr>'; //Prints out the last '<tr>' if one isn't printed.
?>

您需要使用带有模数运算符的 if。
