是while循环" title="while循环">while循环中为while循环中的每三个项目将变量分配给div中的类的一种方式。我使用的是蓝图结构，最后是第三个div，我需要在每个第三个div上附加一个“

last”类名，以便第3 div，第6 div，第9 div等？

/* LOOP THROUGH SHOEDATA TABLE */
$results = mysql_query("SELECT * FROM shoeData");
while($row = mysql_fetch_array($results)){
$name = $row['name'];
$about = $row['about'];
$company = $row['company'];
$buy = $row['buy'];
$tags = $row['tags'];
$id = $row['id'];
$image = $row['image'];
/* ECHO THE SHOEDATA RESULTS */
    echo "<div class='imageBorder span-8 column'>";
        echo "<div id='imageHeight'>";
        echo "<img  src='thumbs/$image'>";
        echo "</div>";
        echo "<ul>";
            echo "<li>$name</l1>";
            echo "<li>$about</l1>";
            echo "<li>$company</l1>";
            echo "<li><a href='$buy'>BUY</a></l1>";
            echo "<li>$tags</l1>";
        echo "</ul>";
    echo "</div>";
}/*SHOEDATA WHILE LOOP ENDS */

回答：

for ($i = 0; $i < $numRecords; $i++)
{
 $className = "";
 if (($i % 3) == 0)
 {
  $className = "last"
 }
 ....
}

这里的关键部分是($i % 3) == 0。

以下是对您的评论的回应。

/* LOOP THROUGH SHOEDATA TABLE */
$results = mysql_query("SELECT * FROM shoeData");
$i = 0;
while($row = mysql_fetch_array($results)){
$i++;
$name = $row['name'];
$about = $row['about'];
$company = $row['company'];
$buy = $row['buy'];
$tags = $row['tags'];
$id = $row['id'];
$image = $row['image'];
/* ECHO THE SHOEDATA RESULTS */         
    $additionalClass = ($i % 3) == 0 ? " last" : "";
    echo "<div class='imageBorder span-8 column" . $additionalClass . "'>";
        echo "<div id='imageHeight'>";
        echo "<img  src='thumbs/$image'>";
        echo "</div>";
        echo "<ul>";
                echo "<li>$name</l1>";
                echo "<li>$about</l1>";
                echo "<li>$company</l1>";
                echo "<li><a href='$buy'>BUY</a></l1>";
                echo "<li>$tags</l1>";
        echo "</ul>";
    echo "</div>";
}/*SHOEDATA WHILE LOOP ENDS */
