Hi Pete.

1) Your regexpression is wrong.
    a) The "+" char is a regex qualifierer, and should be escaped if used as 
a litteral character.
    b) You are only testing if there's ONE letter between A-Z, not more.
2) If you want to test the entire $content, and get the matches returned as 
a array, you should use preg_match_all

Try this:

preg_match_all('/\\+\\+\\+[A-Z]+\\+\\+\\+/', $content,$matches);

$matches then contains an array of the matches found in $content.

BTW: If you are having trouble with Regular Expressions, try RegexBuddy 
http://www.regexbuddy.com/
It allows you to create and test complex regexpresions, and alos contains a 
library of the more common expressions, like validating email addreses etc.
