How to change the database name and pwd in dbconnection.php file

[bunny]

Hi there,
Can you please help me to get out this problem?
Some body developed my website last year and gave it to me, and now I
need to change database password in dbconnection.php file. But problem
is I cannot see the database name and password in the file. Because
they encoded the file. So pls help me how to change the database
password? I really appreciate for that.
They used ioncube software to encode the file, here I'm sending the
dbconnection.php file. Please take a look. I really appreciate for
your help.
