    Always join using the appropriate relationships. As specified in previous comment, you should using id not message/answer

use common b/w each table in your case id so query should be..



SELECT * FROM message JOIN answer ON answer.id = message.id WHERE message = 'hi';



rest in php you should use different ways to run query like prepared statements in order to avoid sql injection or concatenate the variables



like



'SELECT * FROM message JOIN answer ON answer.id = message.id WHERE message = "'.$input.'"';



or mysqli_prepare() bind_params()



or learn using PDO which is good to avoid sql injections as well as supports multiple db drivers which make your work more dynamic and flexible.
