Example #1 MysqlndUhConnection::changeUser() example

<?php
class proxy extends MysqlndUhConnection {
 /* Hook mysqlnd's connection::change_user call */
 public function changeUser($res, $user, $passwd, $db, $silent, $passwd_len) {
   printf("%s(%s)\n", __METHOD__, var_export(func_get_args(), true));
   $ret = parent::changeUser($res, $user, $passwd, $db, $silent, $passwd_len);
   printf("%s returns %s\n", __METHOD__, var_export($ret, true));
   return $ret;
 }
}
/* Install proxy/hooks to be used with all future mysqlnd connection */
mysqlnd_uh_set_connection_proxy(new proxy());

/* Create mysqli connection which is using the mysqlnd library */
$mysqli = new mysqli("localhost", "root", "", "test");

/* Example of a user API call which triggers the hooked mysqlnd call */
var_dump($mysqli->change_user("root", "bar", "test"));
?>

The above example will output:

proxy::changeUser(array (
  0 => NULL,
  1 => 'root',
  2 => 'bar',
  3 => 'test',
  4 => false,
  5 => 3,
))
proxy::changeUser returns false
bool(false)
