Question

Answer 1

For some other reason i don't want to assign variable for password.

You can use the INI settings mysql.default_user and mysql.default_password . See this manual entry .

Answer 2

No way to get back host / username / password, once you have made connection. if you don't want to assign password by using variable use mysql.default_password string which is use when connecting to the database server if no other password is specified. specified in php.ini file.

Warning: any user with read access to php.ini file can reveal the password.
