I'd probably go with preg_match(). 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;

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.
