[SOLVED] Efficiency: is there a simpler || operator in if declaration?

[DamienRoche]

What I want to know is if there is another way to do this:

 

if($var == "1" || $var == "12"){

 

etc etc

 

}

 

Is there not a way of saying if $var is this or this or this without having to declare the var every time?

 

like:

 

if($var == "1","12","34"){

 

 

}

 

Thanks.

The only other way of checking if a variable matches one of many values is to use an array and the in_array() statement - http://us.php.net/inarray

Well, you could create an array and do that:

 

$arr = array("1","12","34");
if(in_array($var, $arr)){
   // Good
}else{
   // Bad
}

I see, thank you very much. That will come in handy in a few other places.

 

Thanks!

There is one other way ... use a switch statement:

<?php
switch ($var) {
   case '1':
   case '12':
   case '34':
//
//   do your work
//
     break;
}?>

Probably overkill here, but it is an option.
