[FX.php List] PHP question

[Dale Bengston]

Hi Trish,

I love preg_match, but for this specific challenge, have you considered using explode()?

If you're always looking for Hall as the last word in a string, then:

	$wordArray = explode(' ', $_POST['Department_Name']);

... will split each word of your string into an array element, and then you just check the value of the last element. So, if your string is "Monty Hall", the resulting exploded array would be:

	0 => Monty
	1 => Hall

$lastElement = count($wordArray) -1;
$lastWord = $wordArray[$lastElement];

if $lastWord = 'Hall' then you have a match.

Hope this helps,
Dale
