always return TRUE. Additionally, an error of the
type E_WARNING may be emitted. The error message may
read like PHP Warning: mysqlnd_uh_set_connection_proxy(): (Mysqlnd User Handler)

Example #1 mysqlnd_uh_set_connection_proxy() example
<?php
$mysqli = new mysqli("localhost", "root", "", "test");
$mysqli->query("SELECT 'No proxy installed, yet'");
class proxy extends MysqlndUhConnection {
public function query($res, $query) {
printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
$ret = parent::query($res, $query);
printf("%s returns %s\n", __METHOD__, var_export($ret, true));
return $ret;
}
}
mysqlnd_uh_set_connection_proxy(new proxy());
$mysqli->query("SELECT 'mysqlnd rocks!'");
$mysql = mysql_connect("localhost", "root", "", "test");
mysql_query("SELECT 'Ahoy Andrey!'", $mysql);
$pdo = new PDO("mysql:host=localhost;dbname=test", "root", "");
$pdo->query("SELECT 'Moin Johannes!'");
?>
以上例程会输出：
proxy::query(array ( 0 => NULL, 1 => 'SELECT \'mysqlnd rocks!\'', )) proxy::query returns true proxy::query(array ( 0 => NULL, 1 => 'SELECT \'Ahoy Andrey!\'', )) proxy::query returns true proxy::query(array ( 0 => NULL, 1 => 'SELECT \'Moin Johannes!\'', )) proxy::query returns true
