例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($rettrue));
   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"));
?>

上の例の出力は以下となります。

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