Separating Arrays

[JREAM]

I can't seem to get these Arrays to separate.

 

if $first_listed_mp3s' are found in $data[$i] -- Don't list in File.

So I would do an if statement inside the while loop and make $data[$i] = ''; if it is found,

but I cant get anything to work.

 

1. I'm trying to have the top items at the top of the file,

2, and the rest of them listed below in whatever order they fall,

3. but I don't want the files listed twice and thats what is happening.

 

<?php

function list_mp3s () {

// Set Directory and Options
$directory = 'public/mp3s/';
$handler = opendir($directory);
$fp = fopen('public/apps/mp3_player/playlist.xml', 'w');

// Write the data as blank, incase new files are added.
$data = '';

// Start the top of the File
$top_of_file .= "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\n";
$top_of_file .= "<xml>\n";
fwrite($fp, $top_of_file);

// 111111111111111111111111111111111111111111
// Write the Top songs to Display
$first_listed_mp3s = array(
'DREAM_ON.mp3', 
'STRAY_DOG.mp3',
'JOLIE.mp3',
'AMERICAN_TRUCKER.mp3',
'LOTTIE.mp3',
'BYE_BABY.mp3',
'FIRE_IN_THE_SUN.mp3',
'JANE_AND_ME.mp3',
'',
);

for ($i = 0; $i < count($first_listed_mp3s); $i++) {
$top_data[$i] .= "\n<track>\n";
$top_data[$i] .= "<path>$directory$first_listed_mp3s[$i]</path>\n";
$top_data[$i] .= "<title>".ucwords(strtolower(str_replace("_"," ", str_replace(".mp3","", $first_listed_mp3s[$i]))))."</title>\n";
$top_data[$i] .= "</track>\n";


fwrite($fp, $top_data[$i]);

}

// Counter
$i = 0;


// 222222222222222222222222222222222222222
// Function Power
while ($file = readdir($handler)) {
if ($file != '.' && $file != '..') {

$data[$i] .= "\n<track>\n";
$data[$i] .= "<path>$directory$file</path>\n";
$data[$i] .= "<title>".ucwords(strtolower(str_replace("_"," ", str_replace(".mp3","", $file))))."</title>\n";
$data[$i] .= "</track>\n";

// Count Individual File
$i++;
}
}

print_r(array_diff($top_data, $data));

// Write Array one by one
for ($i = 0; $i < count($data); $i++) {

fwrite($fp, $data[$i]);
}


$bottom_of_file .= "\n\n</xml>\n";
fwrite($fp, $bottom_of_file);

fclose($fp);
   
// Close Entire Directory
  closedir($handler);
}


// do it
list_mp3s();
?>
