[PHP] Newbie question about good coding practice [isset]

2004-06-05 Thread Al 
if($var) do something;
verses
if(isset($var)) do something;
The simple form if($var) seems to work fine and I see it in code often.
Is there a good reason for using isset?

Yes, if you don't use isset(), you may see notices (errors) if the 
variable is not set. This depends upon the error reporting settings of 
the server. However, if you use isset() you won't see notices 
regardless.

I used to think I was indecisive, but now I'm not so sure.
