E.g. (error handling omitted): preg_match('/([^[]*)(?:\[ Ticket ([0-9]+) \])?/', $subject, $matches); $subject_array['subject'] = $matches[1]; $subject_array['translation'] = isset($matches[2]) ? $matches[2] : false; > The following is what I have tried so far.

It has nothing to do with the "simplified if" (aka. ternary operator[1]), but rather with a superfluous semicolon and a missing closing parentheses. They following should work: $subject_array['subject'] = trim( substr( $subject , 0 , ( strpos( $subject , "[ Ticket " ) > 0 ) ? strpos( $subject , "[ Ticket " ) : strlen( $subject ) ) ); However, keeping the expression simpler by splitting it across multiple statements seems reasonable to avoid such kind of errors.
