EXAMPLES

	See mysqli_real_connect(3).

NOTES

       Note

	      MySQLnd always assumes the server default charset. This charset is sent during connection hand-shake/authentication,  which  mysqlnd
	      will use.

	      Libmysqlclient  uses  the  default  charset  set	in  the  my.cnf  or  by  an  explicit  call  to mysqli_options(3) prior to calling
	      mysqli_real_connect(3), but after mysqli_init(3).

SEE ALSO

       mysqli_init(3), mysqli_real_connect(3).
