setcookie() when logging in and logging out

hey all,
i am writing a login page for an are that utilizes HTTPS. for browsers for IE6.0 and netscape7.0 the page works fine. netscape 6.0 and below plus IE5 and below has problems though. they do not want to set cookies so the login page is continuously showing up. (i know this could be their own browser settings to accept cookies but since i am new to php having some one else look at my code is a good thing). also for netscape 7 and mozzilla 1.1 when they logout the cookie is not reset to "".
any ideas or suggestions on how to improve this or if there are some quirks about PHP that i should know about, please advise!!!!
LOGIN

Code: Select all

<?php
<?php
if ($_SERVER['HTTPS'] !== 'on') {
	die("Please utilize HTTPS://www.testsite.com/Admin/");
}
?>
<?php
if (($userid) && ($password)) {
//query the data
$construct = "dbname=UerDb user=postgres";
$dbh = pg_connect($construct);
	if ($dbh){
		$sql = pg_exec($dbh, "select userid, password from hammersecurity where userid='$userid' and password='$password'");
		$rows = pg_numrows($sql);
		pg_close($dbh);
		if ($rows > 0) {
		for ($i = 0; $i < $rows; $i++) {
		$data = pg_fetch_array($sql, $i);
		$usercookie = $data["userid"];
		setcookie("usercookie","$usercookie",time()+3600,"/Admin/","TestSite.com",1);
		exit (header ('Location:../Admin/'));	
		}
		} else {
		echo "<table align=center valign=middle height=100%><tr><td valign=middle align=center>A Valid UserID and Password must be entered</td></tr></table>";
		}
	} else {
		echo "no connection has been established";
		exit;
	}
}
?>
