[RESOLVED] sessions used with external function files

[emeraldcat]

I have a general sessions question.

If I have most of my functions in a separate file called functions.php:

<?php

function one(){
foo;
}

function two(){
bar;
}

?>

And I call those functions from another page called newpage.php:

<?php
session_start();
include_once 'functions.php';

if (!POST_['submit']){
function one();
}else{
function two();
{

?>

Do I need to have a session_start on my external functions page? Or is it enough to call it once on the calling page?

If I do need start_session in my functions page, do I put it at the top? Or do I have to put it inside of each function?

<?php

function one(){
session_start();
foo;
}

function two(){
session_start();
bar;
}

?>

Does my question make any sense? 😃

You need to start the session prior to including the external functions document (which you've done). Then, when included, the functions have available to them, the same global arrays ($POST, $GET, $_REQUEST) as a normal php page would. It also inherits the parent settings.

So if you start a session, then inlcude 'functions.php', you can use references to session variables; otherwise, you can't.
