resource mysqlnd_uh_convert_to_mysqlnd (mysqli &$mysql_connection) DESCRIPTION
Converts a MySQL connection handle into a mysqlnd connection handle. After conversion you can execute mysqlnd library calls on the connec- tion handle. This can be used to access mysqlnd functionality not made available through user space API calls. The function can be disabled with mysqlnd_uh.enable. If mysqlnd_uh.enable is set to FALSE the function will not install the proxy and always return TRUE. Additionally, an error of the type E_WARNING may be emitted. The error message may read like PHP Warning: mysqlnd_uh_convert_to_mysqlnd(): (Mysqlnd User Handler) The plugin has been disabled by setting the configuration parameter mysqlnd_uh.enable = false. You are not allowed to call this function [...]. PARAMETERS
