PHP virtual

Hi,

I am trying to set up a generic system on my Apache/PHP system.
After setting up aliases and using the "virtual" function in PHP I half accomplished what I was trying to achieve.
I am having troubles with the "header" command however.

For example...

global.php

<?php
session_start();
header("Cache-control: private);
?>

PHP:

(May not be axactly right as I am trying to remember with out seeing the file, but it is correct in the file)

index.php

<?php
virtual("/conf/global.php");
?>

PHP:

This will result in the error "headers already sent".

However, if I do the following...
index.php

<?php
include 'path/to/global.php';
?>

PHP:

It will work.

Are there any known problems trying to set headers while using the "virtual" function?

 

you can edit the php.ini file to turn on output buffering:
http://no2.php.net/ob_start

That should fix those problems

 

Ok, I'll look into that when I get back to my work.

Will it make any changes to my current code or are there any performance issues with using this?

 

Also, this:

<?php
session_start();
header("Cache-control: private);
?>

Needs to be this:

<?php
session_start();
header("Cache-control: private");
?>

 

I did say in the first post underneath that snippet it may be wrong but is correct in the file, I was typing that in quickly and forgot the last speech mark.

 

As for performance issues, you shouldn't encounter any, unless you are running an extremely high traffic site - but then you'd probably do some other measures anyway. The existing code should not be affected by this, no.

 

Hmm, I've turned output_buffering on in my php.ini file and tried using ob_start() but still having the same problem with headers being outputted.
Any ideas?
