每三个div的php while循环变量

是while循环中为div中的类分配变量的一种方法，用于while循环中的每三个项。我正在使用blueprint结构，第三个div在末尾，我需要为每三个div添加一个姓氏，所以第三个div第六个div第九个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 */

与真正的价值相比，MySQL在执行操作时似乎不够聪明

---

您必须指定$sql，$result，因为它看起来像$row=mysql\u fetch\u array$results是真的，所以永远无法加载第一行数据。

如果您想在客户端执行此操作，可以使用CSS3为旧浏览器添加JS[DOMAssistant+Selectivizr]

---

CSS:div.imageBorder:nth-child3n{/*样式属性将应用于每第三个div*/}

如果目的是每X项使用模做一些事情。模是除法的余数，如果除法是一个整数，则为零

if(!($counter%3)) {
    // this is 3 6 9 etc.
}
$counter++;

当然，你可以用任何数字来实现它。

嘿，我对这个很陌生，我如何实现上面的代码，我在上面添加了我的代码

/* 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 */

$sql = "SELECT * FROM shoeData";
$results = mysql_query($sql);
while($row = mysql_fetch_array($results)) {

    // whatever code here 

}

if(!($counter%3)) {
    // this is 3 6 9 etc.
}
$counter++;
