Wrapping a div around every third item in a foreach loop PHP [closed]

问题

//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>
}

This dispalys each "holder" class... but what I am wanting to do is wrap a container around the "holder" class and have 3 "holder" in each "container". eg:

<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>

I cant find out how to either get the index of the associative array, or how to break a foreach loop once %3 == 0.

Any suggestions would be awesome!

You need to have a separate counter variable:

$i = 0;
foreach($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 -->

Are you looking for this? php.net/array_chunk

And, you have some syntax error there

foreach($info as $key => $val){

this should be

foreach($info as $key => $val){ ?>

closing php to start the HTML tag

You would want to do something like this in that case. Make sure to get the variables right.

$i = 1;

foreach($info as $key => $val){
    if ($i % 3 == 0) {
         ?>
         <div name='container'>
         <?php
    }
    ?>
    <div class="holder">
        <div class="name">
            <?php echo $key; ?> 
        </div>
        <div class="colour">
            <?php echo $val; ?> 
        </div>
    </div>

    if ($i % 3 == 2) {
         ?>
         </div>
         <?php
    }

    <?php
    $i++;
}

You can increment $i it inside the foreach loop, e.g:

$i = 0;
foreach ($info as $key => $val) {
    if ($i % 3 == 0) {
        ...
    } else {
        ...
    }
    $i++;
}
