notice and warning


I turned on errors in php:

ini_set('display_errors','1');

And I got a slew of notices and a couple of warnings.

The notices are mostly missing indexes from doing things like this:

$some_var = $_REQUEST['some_name'];

And the warnings are when I have something like this:

Missing argument 1 ...

function someFoo($var1){
if($var1){...}
}

someFoo();

So, I turned display_errors back off, but wonder if I should do anything about the this.

What is good programming practice?

Generally I care more about whether a variable is null or empty, and not whether it has been set, which is what the "notices" seem to be about. If I were to do this:

if(isset($var1)){

// I'd still have to do this:

if($var1){...

PHP is a new language for me, and I'd like to write "correctly"...but I don't want to bloat the code either.

Oh, one more thing, I slipped into perl mode and did this: $SOME_ARRAY{some_key} and got no complaints, Is that "kosher"?
