Display foreach for different keys in an array in PHP - php

Question

I have the following array:
<?php
$sets = array (
array (
'img' => 'file.png',
'heading' => 'Slide Title 1',
'lead' => 'Slide leadription 1',
),
array (
'img' => 'file.png',
'heading' => 'Slide Title 2',
'lead' => 'Slide leadription 2',
),
array (
'img' => 'file.png',
'heading' => 'Slide Title 3',
'lead' => 'Slide leadription 2',
),
array (
'img' => 'file.png',
'heading' => 'Slide Title 3',
'lead' => 'Slide leadription 2',
)
);
?>
Which provides the input for this
<?php
foreach ($sets as $set) {
?>
<!-- START THE FEATURETTES -->
<div class="row featurette">
<div class="col-md-7">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<div class="col-md-5">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
</div>
<?php
}
?>
Now this is working perfectly but I want the md-7 HTML and md-5 HTML to alternate so every other one will now be
<hr class="featurette-divider">
<div class="row featurette">
<div class="col-md-7">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<div class="col-md-5">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
</div>
So basically alternating between the picture and details left-right
UPDATE
As per Jhansen's suggestion This DOES NOT WORK. It will only take the first set, it won't alternate between the two.
<?php
foreach ($sets as $set) {
?>
<!-- START THE FEATURETTES -->
<?php $count = 1; ?>
<?php if( $count % 2 != 0 ): ?>
<hr class="featurette-divider">
<div class="row featurette">
<div class="col-md-7">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<div class="col-md-5">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
</div>
<?php else: ?>
<hr class="featurette-divider">
<div class="row featurette">
<div class="col-md-7">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<div class="col-md-5">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
</div>
<?php endif; ?>`
<?php
}?>

Answer 1

If you're just wanting to alternate, why not encapsulate the html within a modulus statement?
IE,
<?php $count = 1; ?>
<?php if( $count % 2 != 0 ): ?>
... HTML for first arrangement ...
<?php else: ?>
... HTML for second arrangement ...
<?php endif; ?>`

Answer 2

If you want to switch all loops, the proposed jhansen is correct:
<?php
$count=1;
foreach ($sets as $set) { ?>
<!-- START THE FEATURETTES -->
<hr class="featurette-divider">
<div class="row featurette">
<?php if($count % 2 != 0){ ?>
<div class="col-md-7">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<div class="col-md-5">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<?php }else{ ?>
<div class="col-md-7">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<div class="col-md-5">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<?php } ?>
</div>
<?php $count++; } ?>
If you want to switch only the first should do something like this:
<?php
foreach ($sets as $k => $set) { ?>
<!-- START THE FEATURETTES -->
<hr class="featurette-divider">
<div class="row featurette">
<?php if($k==0){ ?>
<div class="col-md-7">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<div class="col-md-5">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<?php }else{ ?>
<div class="col-md-7">
<h2 class="featurette-heading"><?php echo $set['heading']?></h2>
<p class="lead"><?php echo $set['lead']?></p>
</div>
<div class="col-md-5">
<img class="featurette-image img-responsive center-block" src="<?php echo $set['img']?>" alt="Feature">
</div>
<?php } ?>
</div>
<?php } ?>
