page fails to display echo

[Lassie]

I am trying to find a fault which is most bizarre.

I have a simple program to update an array when a page is bookmarked which fails to display and does not show error messages.

After posting on the forum and recieving some help the problem still persits.

I decided to start from basic and build the program again in steps.

The code for the rework is shown below.

I still get the same result  - blank page.

I decided to broaden my checks and am getting some odd results that might indicate a problem with my set up.

If copy code from a simple program that has a header and some html text with little php  (although it is a php page)

I get the text but no headers! The original page shows as normal.

 

I have no idea what to try to track this down and would be grateful for any suggestions.

 

Code for rework which is just the start is

 

<?php
require_once('db_fns.php');
require_once('./includes/config.inc.php');
echo "Requires completed<br /\n";
exit();
?>

 

The link to this page is:-

$target='bookmark_list.php?product_id='.$product_id;
display_bookmark($target, 'bookmark', 'add to browse list');

 

The function is

function display_bookmark($target, $image, $alt)
{
	echo "<a href=\"$target\"><img src=\"images/$image".".gif\" 
           alt=\"$alt\" border=0 height = 57 width = 55></a>";	
}

Also if I just reference the page as http://localhost/e_cart17/bookmark_list.php  - I also get a blank page.
