PHP - 使用include，我可以在页面中的不同div上执行吗？

Question

I have a small problem, and I'll try to break it down into a smaller one so I can explain it properly.

I'm working on a web application and I have a couple of divs, such as this:

<div class="1">
//search bar
</div>

<div class="2">
include_once 'actioncontroller.php';
</div>

<div class="3">

</div>

In the actioncontroller.php I'm having an action controller which decides what action to take depending on what's pressed on the page. I've put it in the second div because ultimately that's where I want to print everything.

My question is, is there any way that I can use the code from the second div in the first one, without it printing it there? Basically I want the search bar from div one to do/print the same thing as the one in div 2 does, but I know(think) that PHP can't see code above the include_once, and if I include the actioncontroller.php in the first div it will print it there, instead of printing it in the second one, as I want.

Hope I was clear enough, it's not a problem of coding, it's just a matter of how can I read the script in the first div and then run it in the second one...

Thanks in advance

This code takes the output of actioncontroller.php and saves it into a variable, which can be echo'd multiple times.

<?php
ob_start();
include_once 'actioncontroller.php';
$output = ob_get_contents();
ob_end_clean();
?>

<div class="1">
    <?php echo $output; ?>
</div>

<div class="2">
    <?php echo $output; ?>
</div>
