PHP中的复杂条件

Question

I need to perform a redirect if user comes from another address than bonaca... or if he typed another pass than 1405 or 999.

The following code is not working properly.

$referrer = $_SERVER['HTTP_REFERER'];

if (!(preg_match("/bonaca.net46.net/",$referrer))
or
!($_POST['pass'] == 1405
or
!$_POST['pass'] == 999)

 {
      header('Location: index.php');
};

Answer 1

From http://php.net/preg_match

Do not use preg_match() if you only want to check if one string is contained in another string. Use strpos() or strstr() instead as they will be faster.

Based on your comment: The following will be true if the referrer does not contain bonaca.net46.net or the password is anything other than 1405 or 999

$referrer = $_SERVER['HTTP_REFERER'];

if (strpos($referrer, "bonaca.net46.net") === FALSE
    || !($_POST['pass'] == 1405 || $_POST['pass'] == 999)
   )
{
      header('Location: index.php');

};
