PHP Flood Protection using session
In the following tutorial we will learn how to stop the undue input from user, to put such kind of constraint you can use the following code. This script prevents users from flooding (posting excessive useless messages) your shout box, poll, comments area, forum etc. To do this, we have to use session, a valuable part of php
Example 1:
<?php
SESSION_start();
if(isset($_SESSION['view']))
{
if($_SESSION['view']< 5)
{
$_SESSION['view']+=1;
$name=$_POST['name'];
$passwd=$_POST['password'];
if($name=='demo'&& $passwd=='demo')
{
echo "hello $name";
}
else
{
header('Location:session.html');
}
}
else
{
echo"<br/>Sorry your maximum turn exceed";
session_destroy();
SESSION_start();
$_SESSION['view']=0;
}
}
?> 0
Output:
If you enter demo in both the text boxes, output will be: 1
hello demo
Otherwise if maximum turn exceed more than 4 times, output will be:
Sorry your maximum turn exceed 2
