need help with conditionals in a template

[TalkVirginia]

I need to display a list of warnings captured in an array.. how would I show them in a template? I'm thinking I would need a warnings template. I'm kinda stuck on the sizeof part though.

if ($isAdmin && is_array($warnings) && sizeof($warnings) > 0) {
	echo '<div id="warnings">';
	foreach ($warnings as $warning) {
		echo $warning;
	}
	echo '</div>';
}

Warnings Template:

<div id="warnings">$warning</div>

PHP Code:

eval('$my_warnings .= " ' . fetch_template('Warning') . '";');
