如何在PHP中的页面之间传输变量？

Question

I am trying to make a login form with PHP, and I want to get a value from a form like so:

$name = $_POST["name"];
$email = $_POST["email"];

then, when the user clicks "Submit", I want the new page to have access to these variables. Using the

include 'file1.php';

technically works, but I dont want ALL of 'file1.php', just the variables. Any Suggestions?

You have to use session. Here is a simple demonstration:

---

page1.php - Load page one to set the session variable

<?php
// begin the session
session_start(); 

// set the value of the session variable 'foo'
$_SESSION['foo']='bar'; 

// echo a little message to say it is done
echo 'Setting value of foo'; 
?>

page2.php - Load page two and it will have access to the session variable you set in page1.php

<?php 
// begin our session
session_start(); 

// echo the session variable
echo 'The value of foo is '.$_SESSION['foo']; 
?>
