mike karthauser gave the correct solution.
The foreach loop should be built to handle any numbers of rows, as it
already does, and then you should do conditional checks within the
loop to know if there are 1, 2 or 3 values in each row, presumably
echoing some alternative content/code for empty values.
I would go for the following with a check to see if the skills array
exists and has rows and would use the shorthand echo if else statement
to but an empty/blank value for empty values.
<?php
if(!empty($skills)):
<div class='single'>
foreach():
<div class='trio'>
<?php echo isset($skill[0]) ? $skill[0] : 'empty'; ?>
<?php echo isset($skill[1]) ? $skill[1] : 'empty'; ?>
<?php echo isset($skill[2]) ? $skill[2] : 'empty'; ?>
</div>
endforeach;
</div>
endif(!empty($skills));
?>
I only just noticed you are echoing fieldset tags. Is this a form you
are echoing out as that would be the only valid reason to use
fieldsets? If so, it is likely that you are manually writing logic
that the form helper can do on your behalf.
