Limit PHP foreach Results - php

Question

I have a section in my footer from a script, that I am trying to customize and that displays the website categories.
Currently the results were limited to 9 results per column and continuing onto x amounts of columns. I need to be able to stop at 2 columns.
Here is the code I have
<div class="left">
<h3 style="padding-top:15px;"><?php echo BROWSE_CATEGORIES; ?></h3>
<?php $footer_category= $this->home_model->get_category(); ?>
<?php if($footer_category) { $ftr_cnt=1; ?>
<ul>
<?php foreach($footer_category as $cat) {
echo '<li>'.anchor('search/category/'.$cat->project_category_id,substr($cat->project_category_name,0,30)).'</li>';
if($ftr_cnt>9) { $ftr_cnt=1; echo "</ul><ul>"; }
$ftr_cnt++;
}
} ?>
</ul>
</div>

Answer 1

Use a break when you've reached 9 * 2, where 2 is the amount of columns you want.
$ftr_cnt = 1;
foreach($footer_category as $cat)
{
echo '<li>'.anchor('search/category/'.$cat->project_category_id,substr($cat->project_category_name,0,30)).'</li>';
if($ftr_cnt == 9)
{
echo "</ul><ul>";
}
$ftr_cnt++;
if($ftr_cnt >= (9 * 2))
{
echo "</ul>";
break;
}
}
