PHP：同时

Question

我遇到了一个问题，我可以在哪里放置我的</tr>，以便它在一段时间内不会重复出现？

<table border="0" cellspacing="0" cellpadding="0" >
<tr>
<?php 
while ($pF = mysql_fetch_array($stringVisits)) 
{ 
    $BuID= mysql_real_escape_string($pF['BuID']);
    $getByInfo = mysql_query("SELECT * FROM users_profile WHERE uID = '$BuID'") or
                die(mysql_error());
    $getByProfile = mysql_fetch_array($getByInfo);
    $getByInf = mysql_query("SELECT full_name, sex FROM users WHERE id = '$BuID'") or
                die(mysql_error());
    $getByProfil = mysql_fetch_array($getByInf);
?>
<td class="viewercell" style="color: #CCC; font-size: 10px;">
<?php 
    echo "<a href='profil.php?id=".$BuID."'>"; 
    echo "<img style='margin-right: 5px; width: 44px; height: 48px; border: 2px solid #FFF; ' src='images/profilePhoto/thumbs/";
    if (!empty($getByProfile["photo_thumb"])) 
    { 
        echo $getByProfile["photo_thumb"]; 
    } else {
        echo "noPhoto_thumb.jpg";
    }
    echo "'>";
?>
</a>
</td>

我想关闭那个<tr>并开始一个新的，但我怎么能这样做？如果我只是将</tr>置于上面的^下，它将复制</tr>，因为它在while()内部如果我在关闭}之后这样做，我就无法使用我的下一个tr中已经while()的$ pF了。

我想在上面的profilephoto下显示一个新的tr。

您可以打开和关闭内部的tr，当您进入循环时向右打开并在退出循环之前向右关闭。请参阅下面的代码，应该做的诀窍

<table border="0" cellspacing="0" cellpadding="0" >
    <tbody>
        <?php
        //  Check result array
        if ($pF) {
            while ($pF = mysql_fetch_array($stringVisits)) {
        ?>
                <tr>        
            <?php
                $BuID = mysql_real_escape_string($pF['BuID']);
                $getByInfo = mysql_query("SELECT * FROM users_profile WHERE uID = '$BuID'") or
                        die(mysql_error());
                $getByProfile = mysql_fetch_array($getByInfo);
                $getByInf = mysql_query("SELECT full_name, sex FROM users WHERE id = '$BuID'") or
                        die(mysql_error());
                $getByProfil = mysql_fetch_array($getByInf);
            ?>

                <td class="viewercell" style="color: #CCC; font-size: 10px;">    
                <?php
                $photo = !empty($getByProfile["photo_thumb"]) ? $getByProfile["photo_thumb"] : "noPhoto_thumb.jpg";

                //
                echo "<a href='profil.php?id=$BuID'>";
                echo "<img style='margin-right: 5px; width: 44px; height: 48px; border: 2px solid #FFF; ' src='images/profilePhoto/thumbs/$photo' />";

                ?>
            </td>
        </tr>
        <?php
            }   // End of While
        } else {
        ?>
            <tr>    
                <td>    
                    No Records!    
                </td>    
            </tr>    
        <?php
        }   // End of check result array
        ?>
    </tbody>
</table>

这是替代解决方案。这不是100％正确，您需要调整它以使其正确。需要确保内部循环始终生成所需的行数。 这将创建行和[X]数量的单元格：

<?php
//  Load data
$data = array();
while ($pF = mysql_fetch_array($stringVisits)) {
    $data[] = $fF;
}

$profilesPerRow = 5;
for ($i = 0; $i < count($data); $i + $profilesPerRow) {
?>
    <tr>                                      
    <?php
    //  Inner Loop, list profiles
    for ($j = $i; $j < $profilesPerRow; $j++) {
        $pF = $data[$i + $j];
        $BuID = mysql_real_escape_string($pF['BuID']);
        $getByInfo = mysql_query("SELECT * FROM users_profile WHERE uID = '$BuID'") or
                die(mysql_error());
        $getByProfile = mysql_fetch_array($getByInfo);
        $getByInf = mysql_query("SELECT full_name, sex FROM users WHERE id = '$BuID'") or
                die(mysql_error());
        $getByProfil = mysql_fetch_array($getByInf);
        $photo = !empty($getByProfile["photo_thumb"]) ? $getByProfile["photo_thumb"] : "noPhoto_thumb.jpg";
    ?>                  

        <td class="viewercell" style="color: #CCC; font-size: 10px;">                                        
        <?php
        echo "<a href='profil.php?id=$BuID'>";
        echo "<img style='margin-right: 5px; width: 44px; height: 48px; border: 2px solid #FFF; ' src='images/profilePhoto/thumbs/$photo' />";
        ?>
    </td>
    <?php
    }   // End of inner loop
    ?>
</tr>
<?php
}   // eND OF OUTER LOOP
?>

Answer 2

一点也不清楚你要做什么。

如果$pF的每个值都要产生多行，则需要将放在中。

Answer 3

把时间放在里面：

<?php
while(){
?>
<tr>
     <td>
          <?=info?>
     </td>
</tr>
<?php
}// END While
?>
