How to pass variables from one php file to another without including it?

Hi all,

I'm working on a new project but I'm stuck.
I'm stuck with passing variables.

Example:

file1.php :

<?php 
$id ="abc123";
?>

PHP:

file2.php :

<?php
echo $id;
?>

PHP:

I want to make this happen . What is the right piece of code for it? (I don't want to 'include' the whole file)

Thanks,

Akos

 

I have this same issue! Can someone post a solution?

 

file1.php sends the id number like this file2.php?id=$id

file2.php

<?php 
$id = $_GET['id'];

echo $id;

?>

Code (markup):

 

Thanks so much! I've got it working.

 

Remember to make the script check if the ID exists.

 

you can redirect from file1.php to file2.php with this : header("Location: file2.php?id=$id");

 

Please take a look at the php session information. It is meant to pass the vars to different php files.

http://www.php.net/manual/en/function.session-start.php

<?php
// page1.php

session_start();

echo 'Welcome to page #1';

$_SESSION['favcolor'] = 'green';
$_SESSION['animal']   = 'cat';
$_SESSION['time']     = time();

// Works if session cookie was accepted
echo '<br /><a href="page2.php">page 2</a>';

// Or maybe pass along the session id, if needed
echo '<br /><a href="page2.php?' . SID . '">page 2</a>';
?>

PHP:

<?php
// page2.php

session_start();

echo 'Welcome to page #2<br />';

echo $_SESSION['favcolor']; // green
echo $_SESSION['animal'];   // cat
echo date('Y m d H:i:s', $_SESSION['time']);

// You may want to use SID here, like we did in page1.php
echo '<br /><a href="page1.php">page 1</a>';
?>

PHP:

If you don't want to have to session_start each time and this is only for your personal server then you could use the php.ini to auto start the session for each user connection.

See below for the var needed to be set to true, 1 in the php.ini file.
session.auto_start boolean - session.auto_start specifies whether the session module starts a session automatically on request startup. Defaults to 0 (disabled).
