Help with variables...

[fearfx]

well thats the thing Im not sure what to use..

PHP Code:

<?php
$curdir = getcwd ();
chdir('/var/www/vhosts/digitalmancave.com/httpdocs/forums');
require_once('/var/www/vhosts/digitalmancave.com/httpdocs/forums/global.php');
chdir ($curdir);
?>
<config>
    <!--Player auto start-->
    <auto_start>true</auto_start>
    
    <!--Format of timer-->
    <time_format>MM:SS</time_format>
    
    <!--Timer visible? (true/false) -->
    <time_visible>true</time_visible>
    
    <!--Track string format-->
    <track_format>#number</track_format>
    
    <!--Track string visible? (true/false) -->
    <track_visible>true</track_visible>
    
    <scroller_speed>5</scroller_speed>    
    <scroller_marquee_content>#TRACK_NAME#</scroller_marquee_content>
    
    <!--Player infobar visible-->
    <infobar_visible>true</infobar_visible>
    <infobar_labels_color>0xFFFFFF</infobar_labels_color>
    <infobar_buffering_color>0x6795FE</infobar_buffering_color>
    
    <!--Repeat button enabled-->
    <repeat_is_enabled>true</repeat_is_enabled>

    <!--Shuffle button enabled-->
    <shuffle_is_enabled>true</shuffle_is_enabled>
    
    <!--Max 4 characters-->    
    <repeat_label_text>REP</repeat_label_text>
    <shuffle_label_text>SHUF</shuffle_label_text>

    <!-- Integers 0 to 100, inclusive -->
    <default_volume>50</default_volume>
    
    <!-- Integers -100 to 100, inclusive -->
    <default_pan>0</default_pan>

    <!--Max 5 characters-->
    <volume_label>VOL</volume_label>
    <pan_label>PAN</pan_label>

    <playlist_click_color>0xC4F3FF</playlist_click_color>
    <playlist_roll_over_color>0x9A9A9A</playlist_roll_over_color>
    
    <!--PLAYLIST 
    Should follow this format:
    path_to_1file,1Title#path_to_2file,2Title#...#path_to_nfile,nTitle
    -->
    <play_list>$userinfo['field15'],Title</play_list>
</config>

That is my config.php file - basically default settings for Music Player and at the end of the file: <play_list> holds the music file links.

So basically at the bottom where it says $userinfo['field15']

is where I want this to show up:

if i'm viewing member.php?u=1

How would I tell my config file that I'm viewing user=1 and I need to gather the info out of ['field15'] so that when I view his profile, it plays the song he inputed in his user cp.
