       mysqlnd_uh.enable = false. The proxy has not been installed [...].

	      mysqlnd_uh_set_connection_proxy(3) 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)
", __METHOD__, var_export(func_get_args(), true));
		 $ret = parent::query($res, $query);
		 printf("%s returns %s
", __METHOD__, var_export($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!'");
	      ?>

	      The above example will output:

	      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
