modifying headers

[Lethe]

When I first run my php script I need to identify my script to others by modifying some sent header information as below...

 

ini_set('user_agent', 'somename');

header('From: myemail@someaddress.com');

flush();

 

I can confirm that ini_set is working by: echo ini_get('user_agent');

 

I can then check - in the same script - my headers using either:

 

foreach (getallheaders() as $name => $value) {

    echo "$name: $value<br />";

}

 

or

 

var_dump($_SERVER);

 

But neither of these show the changed headers. All the headers are still the same.

 

What am I doing wrong?

Ummm, nope still nothing. I've already done everything mentioned in the post.

 

To confirm I try to change the headers before any html is outputted and there are no characters before or after the php tags. I've tried all the suggestions mentioned here http://ca.php.net/manual/en/function.flush.php

 

The header information returned is:

 

Host: localhost:8888

Any suggestions?
