Grammar

Mysql_connect (Server,user,pwd,newlink,clientflag)

parameters	Description
server	Optional. Specify the server to connect to. Can include a port number, such as "Hostname:port", or a path to a local socket, such as ":/path/to/socket" for localhost. If the PHP directive mysql.default_host not defined (by default), the default value is ' localhost:3306 '.
user	is optional. User name. The default value is the user name of the server process owner.
pwd	is optional. Password. The default value is a blank password.
newlink	is optional. If mysql_connect () is invoked the second time with the same argument, no new connection will be established, and the connection ID that is already open will be returned. The parameter New_link changes this behavior and causes mysql_connect () to always open a new connection, even when mysql_connect () was previously invoked with the same parameters.
clientflag	Optional. The Client_flags parameter can be a combination of the following constants: Mysql_client_ssl-using SSL encryption Mysql_c Lient_compress-Use the compression protocol Mysql_client_ignore_space-Allow the interval after the function name mysql_client_interactive-Allow off Interaction timeout before a closed connection time inactive

return value

If successful, returns a MySQL connection identity and returns FALSE if it fails.
