class mysqli { __construct ( [string host [, string username [, string passwd [, string dbname [, int port [, string socket]]]]]] ) }
Opens a connection to the MySQL Server running on.
Parameter Liste
host
Can be either a host name or an IP address. Passing the NULL value
or the string "localhost" to this parameter, the local host is
assumed. When possible, pipes will be used instead of the TCP/IP
protocol.
username
The MySQL user name.
passwd
If provided or NULL, the MySQL server will attempt to authenticate
the user against those user records which have no password only. This
allows one username to be used with different permissions (depending
on if a password as provided or not).
dbname
If provided will specify the default database to be used when
performing queries.
port
Specifies the port number to attempt to connect to the MySQL server.
socket
Specifies the socket or named pipe that should be used.
Anmerkung:
Specifying the socket parameter will not
explicitly determine the type of connection to be used when
connecting to the MySQL server. How the connection is made to the
MySQL database is determined by the host
parameter.
Rückgabewerte
Returns a object which represents the connection to a MySQL Server or
FALSE if the connection failed.
