 * @param string $server The MySQL server. It can also include a port number. e.g.
 * "hostname:port" or a path to a local socket e.g. ":/path/to/socket" for
 * the localhost.
 *
 * If the PHP directive
 * mysql.default_host is undefined (default), then the default
 * value is 'localhost:3306'. In SQL safe mode, this parameter is ignored
 * and value 'localhost:3306' is always used.
 * @param string $username The username. Default value is defined by mysql.default_user. In
 * SQL safe mode, this parameter is ignored and the name of the user that
 * owns the server process is used.
 * @param string $password The password. Default value is defined by mysql.default_password. In
 * SQL safe mode, this parameter is ignored and empty password is used.
 * @param bool $new_link If a second call is made to mysql_connect
 * with the same arguments, no new link will be established, but
 * instead, the link identifier of the already opened link will be
 * returned. The new_link parameter modifies this
 * behavior and makes mysql_connect always open
 * a new link, even if mysql_connect was called
 * before with the same parameters.
 * In SQL safe mode, this parameter is ignored.
 * @param int $client_flags The client_flags parameter can be a combination
 * of the following constants:
 * 128 (enable LOAD DATA LOCAL handling),
 * MYSQL_CLIENT_SSL,
 * MYSQL_CLIENT_COMPRESS,
 * MYSQL_CLIENT_IGNORE_SPACE or
 * MYSQL_CLIENT_INTERACTIVE.
 * Read the section about  for further information.
 * In SQL safe mode, this parameter is ignored.
 * @return resource Returns a MySQL link identifier on success.

 * Installs a callback which decides whether a statement is cached.
 *
 * There are several ways of hinting PELC/mysqlnd_qc to cache a query.
 * By default, PECL/mysqlnd_qc attempts to cache a if caching of all statements
 * is enabled or the query string begins with a certain SQL hint.
 * The plugin internally calls a function named is_select()
 * to find out. This internal function can be replaced with a user-defined callback.
 * Then, the user-defined callback is responsible to decide whether the plugin
 * attempts to cache a statement. Because the internal function is replaced
 * with the callback, the callback gains full control. The callback is free
 * to ignore the configuration setting mysqlnd_qc.cache_by_default
 * and SQL hints.
 *
 * The callback is invoked for every statement inspected by the plugin.
 * It is given the statements string as a parameter. The callback returns
 * FALSE if the statement shall not be cached. It returns TRUE to
 * make the plugin attempt to cage
