DO NOT use php.net example to authenticate user
db table:
id (aurto increment)
user varchar 25(unique)
password varchar (30)
casual_number (30)
login:
select * from utenti WHERE user=POST[user]
....
if(md5(POST[password].$row[casual_number])===$row[password]){
$_SESSION[ok]=true;
}else{
echo "wrong password";
$_SESSION[ok]=false;
}
in any page .php
<?php
session_start();
if(@$_SESSION[ok]==false){
// empty,false and hide empty
header('Location: http://www.example.com/login.php');
exit;
}
echo "proctected page";
?>
