Don't know much about the app you're writing, but does this do the trick for
you?

echo preg_replace ('!
                     (
                      \[quote
                      (?:=[^\]]*)?
                      \]
                     )                # Capture the [quote=xxx] part
                   
                     \n*            # Eliminate any extra newlines here
                   
                     (.+)            # Get contents
                   
                     \n*            # Eliminate any extra newlines here
                   
                     (\[/quote\])    # Capture this part
                   
                     \n*            # Eliminate any extra newlines here
                   
                    !x', "\$1\$2\$3\n\n", $string);

HTH,
