You can get rid of last line in the function. And you can remove "else 
{" and "}" because "if" returns unconditionally. This way it is even 
smaller but speed is the same.

function trimExplode($delim, $string, $onlyNonEmptyValues=0)	{
	$array = explode($delim, $string);
	if ($onlyNonEmptyValues) {
		$new_array = array();
		foreach($array as $index => $value) {
			$value = trim($value);
			if ($value != '') {
				$new_array[] = $value;
			}
		}
		return $new_array;
	}
	foreach($array as $key => &$value) {
		$value = trim($value);
	}
	return $array;
}
