php删除/清除cookie的两种方法

将cookie的值设置为空,即：setcookie('cookiename','')或者setcookie(cookiename,NULL);

将cookie的过期时间设置为过去，即：setcookie('cookiename','',time()-3600);

方法一：将cookie的值设置为空

setcookie ( "cookie_user","test",time () + 60 * 60 * 24 * 30 );

setcookie ( "cookie_pass",md5 ( "test" ),time () + 60 * 60 * 24 * 30 );

function logout() {

setcookie ( "cookie_user","",time () + 60 * 60 * 24 * 30 );

}

logout ();

echo $_COOKIE ['cookie_user'] . "
";

echo "You have successfully logged out.";

?>

第二种方法：将cookie的过期时间设置为过去

setcookie ( "cookie_user",time () - 100 );

setcookie ( "cookie_pass",time () - 100 );

}

logout ();

echo $_COOKIE ['cookie_user'] . "
";

echo "You have successfully logged out.";

?>
