)Used for establishing secure connections using SSL. It must be called before mysqli_real_connect(). This function does nothing unless OpenSSL support is enabled.
Note that MySQL Native Driver does not support SSL before PHP 5.3.3, so calling this function when using MySQL Native Driver will result in an error. MySQL Native Driver is enabled by default on Microsoft Windows from PHP version 5.3 onwards.
link仅以过程化样式：由mysqli_connect() 或 mysqli_init() 返回的链接标识。
