Example #1 MysqlndUhConnection::changeUser() example

  <?php
 class  proxy  extends  MysqlndUhConnection  {
  
  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 ;
 }
}
 
 mysqlnd_uh_set_connection_proxy (new  proxy ());

 
 $mysqli  = new  mysqli ( "localhost" ,  "root" ,  "" ,  "test" );

 
 var_dump ( $mysqli -> change_user ( "root" ,  "bar" ,  "test" ));
 ?>

以上例程会输出：

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