I have an array stored in session and i want to store it into post .

Can i do this? If yes then how?

I want to store all array value in post from session

Answer 1

The opposite should work without any problems.

   $_POST['name'] = $_SESSION['name'];
   $_POST['email'] = $_SESSION['email'];
   $_POST['mno'] = $_SESSION['mno'];
   $_POST['age'] = $_SESSION['age'];

If you want to hold an array you can do it like this:

$datapost = array ( 'name' => $_SESSION['name'], 'email' => $_SESSION['email']);
$_POST['info'] = $datapost;

Answer 2

$_POST is not a persistent store where you can put things. The point of $_POST is that it is populated at the start of the request , with the data that was passed to the server from the client (usually, web browser).

You can write into that array, but it won't have any special effect. It's just an array variable that's globally available in all scopes of your code. Normally, you'd just want to create a new array, and assign whatever you want in there:

$data = [];
$data['stored_foo'] = $_SESSION['foo'];
$data['submitted_foo'] = $_POST['foo'];

If you want to send data back to the browser, you can:

• put it in the output (using echo etc)
• put it in an HTTP header (using the header() function)
• put it in a cookie (which will be sent as an HTTP header, crafted for you by the setcookie() function)
