Question

in a.php I do:

$a = "hello,world";
$_POST['a'] = $a;

in b.php, i want to get $a value, when i echo $_POST['a'], there is no value output. how do i do?

Answer 1

Page a.php:

<?php
session_start();
$a = "hello,world";
$_SESSION["name_anything"] = $a; // This will store $a value to the session
//here i've given session name "name_anything"
?>

Page b.php:

<?php
session_start(); //you need to initiate the session using this function
//You need to session_start() on every page on which you want to use session.
//Even on the page on which you are storing the session.
echo $_SESSION["name_anything"]; //this will print the value of $a
?>
