This script results in one line of output to file, what am I missing?

PHP Code:

 <?php
$conn = mysql_connect("xxx","xxx","xxx"); 
mysql_select_db("xxx",$conn);
$OutputFile = fopen('Orders.txt','w');
$SQL="Select ProjectID From Projects";
$ProjectInfo = mysql_query($SQL);
while ($Info = mysql_fetch_array($ProjectInfo))
    {
        $SQL="Select FileName From PreviewPhoto Where ProjectID = ".$Info['ProjectID'];
        $PreviewPhoto = mysql_query($SQL);[/color][/b]
        while ($Photo = mysql_fetch_array($PreviewPhoto))
            {[/color][/b]
                fwrite($OutputFile, $Photo['FileName'].", ");
                $SQL = "Select Text From PreviewText Where ProjectID = ".$Info['ProjectID'];
                $PreviewText = mysql_query($SQL);
                while ($Text = mysql_fetch_array($PreviewText))
                    {[/color][/b]
                        fwrite($OutputFile, $Text['Text'].", ");
                    }[/color][/b]
                fwrite($OutputFile,"\n");
            }[/color][/b]
    }   [/color][/b]
fclose($OutputFile);       
?>[/color]

Newlines?

I suspect that the culprit is windows notepad, if you try to use it to view the generated file. Windows "new line" characters are "\r\n" (Carriage return + line feed) Linux is "\n" (New line) and mac is "\r" (Carriage return) Notepad must have an \r\n sequence to show a new line. Try to open the file in wordpad, rather than notepad. This program can handle unix/mac new lines, and should display it correctly.

fwrite($OutputFile, $Photo['FileName'].", \n");

Not sure... It looks like he is generating a csv, or something similar. For what I understand, he need several values on one row, separated with comma and then a new line.
