Handling sessions with procedural PHP - php

Question

I would like to dedicate this page to handling sessions using procedural php.
I'll begin with how I start most of my projects:
session_name('Easy_App');
session_start();
if (!isset( $_SESSION['ip'] )){
$_SESSION['ip'] = $_SERVER['REMOTE_ADDR'];
}
if (!isset( $_SESSION['created'] )){
$_SESSION['created'] = time();
}
if (!isset( $_SESSION['overall_views'] )){
$_SESSION['overall_views'] = 1;
}
else {
$_SESSION['overall_views']++;
}
if (!isset( $_SESSION['username'] )){
$_SESSION['username'] = "";
}
if (!isset( $_SESSION['logged_in'] )){
$_SESSION['logged_in'] = 0;
}
/*A quick method to keep pageviews to < 5 pages per 1 second per session*/
if (!isset($_SESSION['first_action'])){
$_SESSION['first_action'] = time();
}
$first_action = $_SESSION['first_action'];
if (!isset( $_SESSION['action'] )){
$_SESSION['action'] = 1;
}
else{
$_SESSION['action']++;
}
$action=$_SESSION['action'];
if ($action>=5){
unset($_SESSION['action']);
unset($_SESSION['first_action']);
if((time() - $first_action) <=1){
exit("Please Don't Hammer My Site ");
}
}
So We have a starting point:
The Start of a session with a few regularly used parameters
In the last few lines, prevention of hammering by casual users.
My question is this:
Where would you go from here? Improvements of the above code or a brief snippet of how you handle sessions using procedural php would be greatly appreciated.

Answer 1

Your code would not work If you are trying to STOP Hammer or FLOODING if the user doesn't keep cookies your Sessions are useless and the script is a waste ... you should try better approach using storage systems like memcache , mongoDB or redis

EDIT 1
Am not sure what you want by procedural PHP but i hope this helps
Objectives
Remove duplicate isset
Remove duplicate if Statement
Create single function to get and set $_SESSION
Trying to make everything a function and hide all variables
Final Code
session_start ();
include("procedural.function.php");
__SESSION ( 'ip', $_SERVER ['REMOTE_ADDR'] );
__SESSION ( 'created', time () );
__SESSION ( 'overall_views', 1 );
__SESSION ( 'overall_views', "++" );
__SESSION ( 'username', "" );
__SESSION ( 'logged_in', 0 );
__SESSION ( 'first_action', time () );
__SESSION ( 'action', "++" );
if (__SESSION ( 'action' ) >= 5) {
__UNSET ( 'action' );
__UNSET ( 'first_action' );
if ((time () - __SESSION ( 'first_action' )) <= 1) {
exit ( "Please Don't Hammer My Site " );
}
}
procedural.function.php
function __SESSION($var, $value = null) {
if ($value === null) {
return isset ( $_SESSION [$var] ) ? $_SESSION [$var] : null;
} else if ($value === "++") {
isset ( $_SESSION [$var] ) ? $_SESSION [$var] ++ : $_SESSION [$var] = 0;
return $_SESSION [$var];
} else {
isset ( $_SESSION [$var] ) ? $_SESSION [$var] = $value : null;
return $value;
}
}
function __UNSET($var) {
unset ( $_SESSION [$var] );
}
