Parse error: syntax error, unexpected T_STRING

My site has been hacked I installed site scanners on the 21 and got hacked on the 23 now I cannot access my site. I am trying to reconfigure my wp_config.php but keep getting this error.
Parse error: syntax error, unexpected T_STRING in /home/content/83/11367183/html/wp-config.php on line 28.
It is the last line of the code. I have entered the db fields one by one. If I start with the DB_HOST it is fine, as soon as I add my username and password it goes wrong.

Please help

TIA
