conditional commands

[formula455]

Hi.. if i remember right this code i'm about to show used to work. I don't know if i'm doing something wrong... or if my webserver is just not supporting it.

 

<? if($var == (("condition1") || ("condition2"))) { echo "fubar"; } ?>

 

basically if $var is either condition1 or condition2 it would echo fubar. what's happening is on my webserver it's echoing fubar reguardless of what either condition is. if i make each condition seperate it works.. like so....

 

<? if($var == "condition1" OR $var == "condition2") { echo "fubar"; } ?>

 

i could technically do it this way... if theres going to be alot of conditions and i would prefer to use the first route.

 

so yah if theres something i'm doing wrong please gimmi the heads up otherwise i guess its my webserver not allowing the conditional commands

Hey mate.

 

I am no expert but in the first statement I think you are telling php to check :

 

if($var == condition1) or if condition2 is true. It is not comparing var to condition 2. And I guess condition 2 will always be true since it is not getting compared to something , so the whole expression will always be true so .. it will always echo"fubar";

 

Ofcourse I might misunderstand something but I hope I helped.

^^^ Yep that's basically it so change your code to

 

<?php
if($var == "condition1"|| $var == "condition2") { echo "fubar"; }
?>

i figured that's what I would have to do =/

 

so theres no way of getting around repeatingly typing the variable $var?

well you could use a switch statement if you got too many checks to make:

 

switch($var)
{
     case condition1:
     case condition2:
     case condition3:
     case condition4:
     .....................
      case conditionn:
          echo"fubar";
            break;
     default:
        echo"not fubar ";
          break;
}

Or an array.

 

<?php

  $conditions = array('foo','bar','bob');
  if (in_array($var,$conditions)) {
    echo '$var matches a condition';
  }

?>
