Hello dosto, is video series me hum session ka concept sikhenge, sath hi hum session ka use krke form validation bhi sikhenge.

Session har programming language me ek bohot hi important role play karta hai. Login se lekar logout tak ye sara kaam bhi session ke through hi hota hai.

Session ek temporary file hoti hai jo server per create hoti hai or server per hi store hoti he. Or jab tak hum self session ko destroy nahi kr dete tab tak session server me active rehta he. Session ka concept cookies ki tarah hi hai. Bas difference ye hai ki cookies local PC me store hoti he or session server per store hota he.

Isliye server per store hone ki wajah se session cookies se zyada secure hota he.

Hum session use krke ek variable ko ya ek hi information ko more than 1 pages per or multiple time use kr sakte hai. Or session me hum koi bhi information ya value store kar sakte he.

Session PHP me ek Global Variable hota he. Or ise PHP me $_SESSION type krke use kia jata hai. Session ko use krne ya session ko create, destroy krne ke liye hume sabse pehle session ko start karna hota he. Session ko start krne ke baad hi hum use use kar sakte hai. Without session start hum session ko use nahi kar sakte.

Please note the syntax and some points of the session :-

1. For Session start
session_start();

2. For Create session
$_SESSION["name of session"] = Variable or Information;

3. For Store session in any variable
Any variable name = $_SESSION["name of session"];

4. $_SESSION must be written in upper case letters.
