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. 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.seealso; mysqli_connect, mysqli_init, mysqli_options, mysqli_ssl_set, mysqli_close. 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(); ?> ]]> ]]> The above examples would produce the following output:
