Removing all text from string prior to delimiter

[mrgrammar]

I have several categories; some of them have subcategories. The double colon (:🙂 is the delimiter between the subcategories.

$item[1] = 'Food';
$item[2] = 'Food::Bottled_Water';
$item[3] = 'Food::Candy';
$item[4] = 'Food::Candy::Burstin_Bits';
$item[5] = 'Food::Candy::Chocolate';

I need to strip off everything except the last (sub)category. For example:

'Food' above is fine.
For 'Food::Bottled_Water', I just need 'Bottled_Water'.
For 'Food::Candy::Chocolate', I just need "Chocolate".

Is there a quick way to loop through the strings above to strip away what I don't need?

(I thought about using explode(), but the needed string would not necessarily appear as the same array piece for each one.)

explode is correct, the last piece can be selected using end()

Would this work?

$display_name = array();
foreach($item AS $i){
	$item_split = preg_split('::',$i);
	echo end($item_split);
}

would it?
did you test it?
did it work ?
if no what happened, if yes, then why are you asking ? :-)
