I have names like this:

$str = 'JAMES "JIMMY" SMITH'

I run strtolower, then ucwords, which returns this:

$proper_str = 'James "jimmy" Smith'

I'd like to capitalize the second letter of words in which the first letter is a double quote. Here's the regexp. It appears strtoupper is not working - the regexp simply returns the unchanged original expression.

$proper_str = preg_replace('/"([a-z])/',strtoupper('$1'),$proper_str);

Any clues? Thanks!!
