IF listing

[Mutley]

Is it possible to check multiple variables in an IF statement at once? Like instead of doing:

 

if($this == NULL || $that == NULL || $thing == NULL)

 

todo something like

 

if($this, $that, $thing == NULL)

 

Thanks.

use a switch or wht you got already ok

I would have thought that the way to do that is like:

 

if ($this is NULL || $that is NULL || $thing is NULL)

{

 echo "do something";

 }

The problem with doing == NULL for each one is that it takes too much code, can't I just do == NULL once? And just list them.

I'm pretty sure that if you go...

 

if($this, $that, $thing is NULL)

{

  echo "do something";

  }

 

...and (say) $this actually *is* NULL, then $that and $thing won't even be checked because the first part of the if statement is already shown to be true....

 

$this = 'NULL';

 

if($this, $that, $thing is NULL)

{

  echo "do something";

  }

 

...so in the above $this actually is NULL so the statement is already true and $that and $thing won't even be looked at by the statement.

Tell me, what happened when you tried it?
