它们是while循环中的一种方式,可以为div中的类分配变量,用于while循环中的每个第三项.我正在使用蓝图结构,第三个div在最后,我需要为每个第三个div附加一个“最后”类名,所以第3个div第6个div第9个div等等？
/* 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>$tags</l1>"; echo "</ul>"; echo "</div>"; }/*SHOEDATA WHILE LOOP ENDS */
解决方法
for ($i = 0; $i < $numRecords; $i++)
{
$className = "";
if (($i % 3) == 0)
{
$className = "last"
}
....
}
这里的关键部分是($i％3)== 0.
