Check if variable is different from several values

Question

If I want to take an action if php if a variable isn't 0,1, or 2, how would I do that? my if statement isn't working. Thanks!

Solution 1

if (($var != 0) && ($var != 1) && ($var != 2)) {
    //...
}

or...

if (!in_array($var, array(0, 1, 2))) { /* ... */ }

See logical operators.

Solution 2

The most straightforward way:

if ($x != 0 && $x != 1 && $x != 2)
{
    // take action!
}

If you know your variable is an int, then you could also do like:

if ($x < 0 || $x > 2)
{
    // take action!
}
