PHP Sort & Delete

Hi,
My page is at: http://webwirepublishing.com/contact.html
I am trying to get the names to sort and delete duplicates with user input (button) and it does not work. Can you take a look at the script? It is inside an Iframe
HTML:
<div id'"frameHolder">
<IFRAME src="GuestBook.php" width="200" height="750" style="border: 2px solid #333; width: 750px; height: 750px; "><A href="GuestBook.php" target="new" style="color:darkred">Click here to see the latest quotes </A>
                   </IFRAME></div>
<html>
      <head>
            <meta charset="UTF-8">
           <title>Guest Book CURRENT</title>
</head>
     <body>
<?php
if (isset($_POST['submit'])) {
      $firstName = stripslashes($_POST['first_name']);
$lastName = stripslashes($_POST['last_name']);
$wholeName = $firstName . ' ' . ($lastName);
      $guestRecord = "$wholeName\n";
$guestBook = fopen("guestbook.txt", "ab");
if ($guestBook === FALSE)
     echo "There was an error saving your name!";
else {
     fwrite($guestBook, $guestRecord);
           fclose($guestBook);
                 echo "<strong>Your entry has been saved. Current Guest List:</strong>.";
}
      }
// if info then process
if (isset($_GET['submit'])) {
     if ((file_exists("guestbook.txt")) && (filesize("guestbook.txt") != 0)) {
            $guestArray = file("guestbook.txt");
     //switch to $_Get Method
switch ($_GET['action']) {
// remove duplicate entries
case 'Remove Duplicates':
      $guestArray = array_unique($guestArray);
      $guestArray = array_values($guestArray);
      break;
case 'Sort Ascending':
      sort($guestArray);
      break;
      }
//count to see how many entries there are
      if (count($guestArray)>0) {
      $newGuest = implode($guestArray);
$guestStore = fopen("guestbook.txt", "ab");
if ($guestStore === false)
      echo "There was an error updating the message file";
else {fwrite($guestStore, $newGuest);
      fclose($guestStore);
            }
      }
else
unlink("guestbook.txt");}
}
if ((!file_exists("guestbook.txt")) || (filesize("guestbook.txt") == 0))
      echo "<p>There are no entries.</p>";
else {
// txt file empty show an error
if ((!file_exists("guestbook.txt")) || (filesize("guestbook.txt") == 0))
echo "<p>There are no entries.</p>"; else {
      //if array exists display the txt file in a table
      $guestArray = file("guestbook.txt");
            echo "<table style=\"background-color:white\" border=\"0\" width=\"75%\">";
//count number of guest names
$count = count($guestArray);
      for ($i = 0; $i < $count; ++$i) {
$currMsg = explode("~", $guestArray[$i]);
// TABLE to display results:
            echo "<td width=\"95%\"><span style=\"font-weight:bold\"></span>" . htmlentities($currMsg[0]);
            echo "</tr>\n";
}
echo "</table>";
}
}
?>

$guestArray is just the contents of guestbook.txt - it is not an array but you are treating it as if it was
