Parse Error for Databse on line 31

I have never seen this parse error before (Parse error: syntax error, unexpected 'DB_PASSWORD' (T_STRING), expecting ',' or ')' in /home/www/ on line 36), as usually it should come up with a "Error Establishing a Database Connection" whenever the credentials are wrong.

I have double checked Line 31, and the password is correct and to my knowledge everything is spaced and has appropriate ' markers.
