(PHP 5)
mysqli::options -- mysqli_options — Set options
面向对象风格
过程化风格
Used to set extra connect options and affect behavior for a connection.
This function may be called multiple times to set several options.
mysqli_options() should be called after mysqli_init() and before mysqli_real_connect().
仅以过程化样式：由 mysqli_connect() 或 mysqli_init() 返回的链接标识。
The option that you want to set. It can be one of the following values:
| Name | Description |
|---|---|
| MYSQLI_OPT_CONNECT_TIMEOUT | connection timeout in seconds (supported on Windows with TCP/IP since PHP 5.3.1) |
| MYSQLI_OPT_LOCAL_INFILE | enable/disable use of LOAD LOCAL INFILE |
| MYSQLI_INIT_COMMAND | command to execute after when connecting to MySQL server |
| MYSQLI_READ_DEFAULT_FILE | Read options from named option file instead of my.cnf |
| MYSQLI_READ_DEFAULT_GROUP | Read options from the named group from my.cnf or the file specified with MYSQL_READ_DEFAULT_FILE. |
The value for the option.
成功时返回 TRUE， 或者在失败时返回 FALSE.
Note:
MySQLnd always assumes the server default charset. This charset is sent during connection hand-shake/authentication, which mysqlnd will use.
Libmysql uses the default charset set in the my.cnf or by an explicit call to mysqli_options() prior to calling mysqli_real_connect(), but after mysqli_init().
