connectionMysqlnd connection handle. Do not modify!
Connection statistics collected by mysqlnd.
Example #1 MysqlndUhConnection::getStatistics() example
<?php
class proxy extends MysqlndUhConnection {
public function getStatistics($res) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::getStatistics($res);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli = new mysqli("localhost", "root", "", "test");
var_dump($mysqli->get_connection_stats());
?>
以上例程会输出：
proxy::getStatistics(array (
0 => NULL,
))
proxy::getStatistics returns array (
