Description:
------------
I have a problem in if statment, where i if with more than one statment. i would prefer this method instead nested if statments. I also tried instead "or" i used "||" syntax.

Reproduce code:
---------------
$form['option_form']['method'] = "post";

if ($form['option_form']['method'] != "post" or $form['option_form']['method'] != "get" or $form['option_form']['method'] != "submit")
{
    die ("In this case it will run this part of IF statment, but it shoudn't");
}
else
{
    die("This part it shoudnt do it.");
}
