I am having a hard time with getting my code to write the txt file. Any ideas?

Song Organizer

// create a song organizer script

$filename = 'songs.txt';

$filepath = __DIR__ . '/' . $filename;

$songs = [];

if (isset($_GET['action']))

{

if ((file_exists("SongOrganizer2/songs.txt"))

&& (filesize("SongOrganizer2/songs.txt")!= 0))

{$SongArray = file("SongOrganizer2/songs.txt");

switch ($_GET['action'])

{

case 'Remove Duplicates';

$SongArray = array_unique($SongArray);

$SongArray = array_values($SongArray);

break;

case 'Sort Ascending':

sort($SongArray);

break;

case 'Shuffle':

shuffle($SongArray);

break;

} // End of the switch statement

if (count($SongArray) > 0)

{

$NewSongs = implode($SongArray);

$SongStore = fopen("SongOrganizer2/songs.txt","wb");

if ($SongStore === false)

echo "There was an error updating the song file ";

else

{fwrite($SongStore, $NewSongs);

fclose($SongStore);

}

} else

unlink("SongOrganizer2/songs.txt");

}

}

if(isset($_POST['submit']))

$SongToAdd = stripslashes($_POST['SongName']) . " ";

$ExistingSongs = array();

if (file_exists("SongOrganizer2/songs.txt")

&filesize("SongOrganizer2/songs.txt")> 0)

{ $ExistingSongs = file("SongOrganizer2/songs.txt");}

if (in_array($SongToAdd, $ExistingSongs))

{echo "

The song you entered already exists!
";

echo "Your song was not added to the list.

";

}

else

{

$SongFile = fopen("SongOrganizer2/songs.txt","ab");
