[SOLVED] or in an if statment

[Comdemned]

Hi,

 

Is there anyway to have a or in an if statment

eg

<?php
if (!$_SESSION['perm'] = 1 or 2){
die("you shouldnt be here");
}
?>

 

or do you have to so it like

 

<?php
if (!$_SESSION['perm'] = 1){
if (!$_SESSION['perm'] = 2){
die("you shouldnt be here");
}
}
?>

also when doing it this way is there any way to stop the if statment from setting $_SESSION['perm'] = 2 as it is and its messing with my authentication.

 

Ive searched the forums lots but its kind of hard to search for "or" as it shows up so often.

 

Thanks in advance

Murray

Thank you that has solved both problems,

I thought the || in an if statment ment AND not OR.

Also i noticed you used == instead of =, which has fixed the problem of the if statment setting $_SESSION['perm'] =2,

what exactly does == mean compared to = other that it will not update the variable?

the = sets the variable and == compares the left and the right side:

 

$id = 3; // Sets $id to 3
if ($a == $b) { // Checks if $a has the same content as $b
    
}
