//set the array
$info = array(
'andy' => 'blue','andrew' => 'black','mark' => 'green','jane' => 'orange','simon' => 'red','joan' => 'pink','sue' => 'yellow','alan' => 'black')
$i = 1;
foreach($info as $key => $val){
<div class="holder">
<div class="name">
<?PHP echo $Name ?>
</div>
<div class="colour">
<?PHP echo $colour ?>
</div>
</div>
}
这显示了每个“持有者”类…但我想要做的是在“持有者”类周围包装一个容器,并在每个“容器”中有3个“持有者”.
例如：
<div class="container">
<div class="holder">
<div class="name">
<?PHP echo $Name ?>
</div>
<div class="colour">
<?PHP echo $colour ?>
</div>
</div>
<div class="holder">
<div class="name">
<?PHP echo $Name ?>
</div>
<div class="colour">
<?PHP echo $colour ?>
</div>
</div>
<div class="holder">
<div class="name">
<?PHP echo $Name ?>
</div>
<div class="colour">
<?PHP echo $colour ?>
</div>
</div>
</div>
我不知道如何获得关联数组的索引,或者如何在％3 == 0时打破foreach循环.
任何建议都很棒！

解决方法
你需要一个单独的计数器变量：
$i = 0;
foreach($info as $key => $val){
if($i%3 == 0) {
echo $i > 0 ? "</div>" : ""; // close div if it's not the first
echo "<div class='container'>";
}
?>
<div class="holder">
<div class="name">
<?PHP echo $Name ?>
</div>
<div class="colour">
<?PHP echo $colour ?>
</div>
</div>
<?PHP
$i++;
}
?>
</div> <!-- close last container div -->
