	array_shift($MessageArray);
	$NewMessages = implode($MessageArray);
	$MessageStore = fopen("messages.txt", "w");

before i look through it, let us know if there are errors and such. Or maybe try telling us what it is that you are trying to do.

the errors are as follows coming from wdg html validator:

From an xhtml perspective:

<html xmlns= "http://www.w3.org/1999/xhtml">

has an extra space.

you have two <html> tags. you didn't define any <head> or <body> sections.

since you don't need this to be view in a web browser, get rid of all the html.

In the PHP portion:

try this:

<?php

$file = 'messages.txt';
if ( file_exists( $file ) && filesize( $file ) !== 0 ) {
	$messageArray = file( $file );
	array_shift( $messageArray );
	$messageStr = implode( "\n",$messageArray );
	$fh = @fopen( $file,'w' ) or die( 'Unable to open file' );
	@fwrite( $fh,$messageStr ) or die( 'Unable to write to file' );
	@fclose( $fh );
}
header( 'Location: ViewDiscussion.php' );
exit;

?>
