Question

I think sometimes I don’t need to use ELSEIF and not repeat stuff by maybe doing multiple checks inline.

I’ve done this before.

I’m trying this simple line and just can’t make it work.

I read that:

OR is the same as ||

AND is the same as &&

Code (The short way, but doesn’t work):

if($subdom<>'www' or $subdom<>'nosub') {do some stuff if any of the two are meet} 

I also tried this:

Code:

if((subdom!='www') || ($subdom!='nosub')){} 

What will be the correct operators to check for any of the two? Is it || or &&. Should we use != or <> also?

Some Info found after question answered:

$a && $b
//And //TRUE if both $a and $b are TRUE.

$a || $b
//Or //TRUE if either $a or $b is TRUE.

Either of these will work as the comparison:

!== (not equal identical), but not != as it will mean ‘does not assign’
<> will do the trick without too much merry go round.

Answer 1

Your expression is always true, considering your example, check the table with different input values for $subdom:

$expr = ($subdom!=’www’) || ($subdom!=’nosub’);

    $subdom      ($subdom!='www')      ($subdom!='nosub')      result    ¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯¯     www      |      false           |        true         |     true  |     nosub    |      true            |        false        |     true  |     anything |      true            |        true         |     true  |     blah!    |      true            |        true         |     true  | 

I think you’re wanting to use the AND (&&) operator here…
