[RESOLVED] isset switch case with 0 notice?

[hayato1]

i think what i have written all along given too much notice,
if i on the error log it gonna be few mb by 10sec...

i hope someone can teach me from the beggining to help me rewrite everything

am i going to write this for every switch?

<?php
switch ( isset($_GET['i']) ? $_GET['i'] : NULL) {
case NULL:
	echo "i is not equal to 0, 1 or 2";
	break;
case 0:
	echo "i equals 0";
	break;
case 1:
	echo "i equals 1";
	break;
case 2:
	echo "i equals 2";
	break;
}
?>

or should i write this

<?php
if (isset($_GET['i'])) { 
	if ($_GET['i'] == 0 ) { echo "i equals 0"; }
		elseif($_GET['i'] == 1 ) { echo "i equals 1"; }
		elseif($_GET['i'] == 2 ) { echo "i equals 2"; }
		//70+ elseif here?
} else { echo "i is not equal to 0, 1 or 2";}
?>

or all i have gotten is wrong? please teach me the best way.. thanks

if(isset($_GET['i']) && is_numeric($_GET['i']))
  echo 'i equals '.$_GET['i'];

I guess I dont really understand why you need a million conditionals when all you want is what i equals.

oh, i just pull the examples from www.php.net/switch
for my side i have if NULL and numberic to string switch so i wonder how do i do a switch without notice..

edit, hm i think i gotten it somehow (abit) but do you know how to get this correct?

if(isset($_GET['d']) && is_numeric($_GET['d'])) {
if(isset($_GET['s']) && ($_GET['s']==1)) { $filename="^IMAGE/".$name.""; } else { $filename="^IMAGE/b/".$name.""; }

$len = filesize($filename);
$hash = md5($filename);
$headers = getallheaders();//SOMETHING WRONG?

// if Browser sent ID, we check if they match
if (ereg($hash, $headers['If-None-Match']))//SOMETHING WRONG?
{
header('HTTP/1.1 304 Not Modified');
}else {
	header("ETag: \"{$hash}\"");
	header("Accept-Ranges: bytes");
	header('Content-Length: '.$len.'');

i think somehow if-none match was wrong isn't it supposed to be. like
if (ereg("^([0-9)*)", $hash))//?
anyway the notice gives me
