是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>$tags</l1>"; echo "</ul>"; echo "</div>"; }/*SHOEDATA WHILE LOOP ENDS */
for ($i = 0; $i < $numRecords; $i++) { $className = ""; if (($i % 3) == 0) { $className = "last" } .... }
这里的关键部分是($i % 3) == 0。
($i % 3) == 0
