[RESOLVED] Help with(isset($_COOKIE["user"]))

[Ralph2]

How can I run this code only if a cookie is not set. This is part of my logon script which writes login attempts to a txt file. Because the logon script is run for each page I get multiple entries while the intent is only to let me know who is having trouble logging on. What I "think" I need is a isNOTset function, if a cookie is not set run this code, if it is set do nothing

Thanks for any help

$logfile = '/home/lxxxx/public_html/xxxxx/log.txt';
$date = date('j M Y H:i:s');
$address = 'Unknown';
if (isset($_SERVER['REMOTE_ADDR'])) {
	$address = $_SERVER['REMOTE_ADDR'];
}
if ($file = @fopen($logfile, 'a')) {
  fwrite($file, "\r\n$date $address $user $password");
  fclose($file);
}

Just negate an isset() with the "!" operator:

if(!isset($_COOKIE['fubar'])) {
   // do something if cookie is not set
}

Or if you prefer, you might find it more "readable" to do:

if(isset($_COOKIE['fubar']) == false) {
   // do something if cookie is not set
}

Or, under the theory that there is always more than one way to do it:

if(empty($_COOKIE['fubar'])) {
   // do something if cookie is not set or if it has a value of 0, '', or FALSE
}

Thank you NogDod

That is exactly what I needed to know.
