[FX.php List] PHP Notices OK?

[Steve Winter]

Hi Jonathan,

Yes, you could declare them at the top of the page if you were sure that
they were going to exist... I usually find that the time at which I get that
error is when I've done something like..

if(something) {
  do a bunch of stuff;
  which may or may not result in;
  $myVariable = something;
}

And usually that means that at some point I later want to know if that
variable has been set so I can do something with it, so I do;

if(isset($myVariable)) {
  do whatever
}

YMMV

Cheers
Steve

OK. That's fair.

To be honest, I never knew about these things since I have developed 
on my own server and Notices are turned off....until now. ;-)

One step further...my notices appear to be of the Undefined Variable 
type.  I did see your suggestion from last week, to add in 
if(isset($variable)) rather than "surprise" PHP when an undeclared 
variable appears.  Is another alternative to simply declare the 
variable at the top of he page?  If so, how is that best done?

Thx

Jonathan
