note 112454 added to function.preg-match

Can anyone help me here? I’m trying to make a program that checks if a keyword is found on the title of a website. Like the keywords are stored in a variable $keywords and I'd like to check if they exist in $title. The keywords can vary in numbers and they are usually separated by commas. How do I do that?
