Multiple index variables in PHP foreach loop

I am trying to create a before and after image display using mysqli, php and html.
I am pulling the records from the db with mysqli and php, and am trying to view the results in an Unordered List using a foreach loop.

I have my 2 arrays which are created above in a while loop of a mysqli query. The array will only contain 5 results (for pagination, may change later).

$before_array[] = '
<div class="highslide-gallery">
<li>
<a href="'.$beforeurl.'" class="highslide" onclick="return hs.expand(this)">
<img src="'.$beforeurl.'" width="100px" height="125px" alt="Highslide JS">
</a>
</li>';

$after_array[] = '
<li><a href="'.$afterurl.'" class="highslide" onclick="return hs.expand(this)">
<img src="'.$afterurl.'" width="100px" height="125px" alt="Highslide JS">
</a>
</li>';

and in the view of the page I have the following code to display the before and after pictures.

<div id="hoverwrap">
<ul class="hoverbox">;

<?php 
foreach ($before_array as $value) {
    echo $value; 
 }

foreach ($after_array as $value) {
  echo $value;
}
?>

</ul>

</div><!-- end of hoverwrap div-->

With the current code it is displaying the pictures :
before – before – before – before – before – after – after – after – after – after.

Where I would like it to diplay:
before – after – before – after etc etc.

I was thinking a while loop but no matter which way I try and implement it, it results in a similiar display.
Any help or pointers in the right direction will be greatly appreciated.

Thanks.

Answer 1

A for loop will do the trick here:

$x = count($before_array);
for($i = 0; $i < $x; $i++) {
    print $before_array[$i];
    print $after_array[$i];
}

Why can’t you print it in the mysql loop itself?
