mysqli_real_connect mysqli->real_connect() Opens a connection to a mysql server &reftitle.description; Procedural style boolmysqli_real_connect mysqlilink stringhost stringusername stringpasswd stringdbname intport stringsocket intflags Object oriented style (method) mysqli boolreal_connect stringhost stringusername stringpasswd stringdbname intport stringsocket intflags Establish a connection to a MySQL database engine. This function differs from mysqli_connect: mysqli_real_connect needs a valid object which has to be created by function mysqli_init. With function mysqli_options you can set various options for connection. There is a flags parameter. &reftitle.parameters; &mysqli.link.description; 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. 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. flags With the parameter flags you can set different connection options: Name Description MYSQLI_CLIENT_COMPRESS Use compression protocol MYSQLI_CLIENT_FOUND_ROWS return number of matched rows, not the number of affected rows MYSQLI_CLIENT_IGNORE_SPACE Allow spaces after function names. Makes all function names reserved words. MYSQLI_CLIENT_INTERACTIVE Allow interactive_timeout seconds (instead of wait_timeout seconds) of inactivity before closing the connection MYSQLI_CLIENT_SSL Use SSL (encryption) For security reasons the MULTI_STATEMENT flag is not supported in PHP. If you want to execute multiple queries use the mysqli_multi_query function. &reftitle.returnvalues; &return.success; &reftitle.examples; options(MYSQLI_INIT_COMMAND, "SET AUTOCOMMIT=0"); $mysqli->options(MYSQLI_OPT_CONNECT_TIMEOUT, 5); /* connect to server */ $mysqli->real_connect('localhost', 'my_user', 'my_password', 'world'); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } printf ("Connection: %s\n.", $mysqli->host_info); $mysqli->close(); ?> ]]> ]]> &example.outputs; &reftitle.seealso; mysqli_connect mysqli_init mysqli_options mysqli_ssl_set mysqli_close
