Unable to zip more than one file at a time

I wrote a very simple web form that allows my user to view text files from within their Internet browser.

Occasionally, the search criteria entered returns more than one file. So I want to implement a feature whereby the text files returned by the search are compressed into a ZIP.

I got a prototype working but it only compresses the first file. The second or third files are ignored.

Here's my code

 <HTML><body><form name="myform" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
 <fieldset><label for="DBRIDs">RIDs</label><input type="text" id="DBRIDs" name="DBRIDs" >
 </fieldset></form></body></HTML>
 <?php
 function check_search() {
  if (isset($_POST['submit'])) {if (!empty($_POST['DBRIDs'])) { $results = getFiles(); }
   }  else $errors = "Please enter something before you hit SUBMIT.";
  return Array($results, $errors);
 }
 function getFiles() {
  $result = null;
  $ZIPresult = null;
  if (empty($_POST['DBRIDs'])) { return null; }
  $mydir = MYDIR; 
  $dir = opendir($mydir);
  $DBRIDs = $_POST['DBRIDs'];
  $getfilename = mysql_query("select filename from search_table where rid in (" . $DBRIDs . ")") or die(mysql_error());
  while ($row = mysql_fetch_array($getfilename)) {
  $filename = $row['filename'];
  $result .= '<tr><td><a href="' . basename($mydir) . '/' . $filename . '" target="_blank">' . $filename . '</a></td></tr>';
  $ZIPresult .= basename($mydir) . '/' . $filename;
 } 
 if ($result) {
 $result = "<table><tbody><tr><td>Search Results.</td></tr> $result</table>";
 shell_exec("zip -9 SearchResult.zip ". $ZIPresult ." > /dev/null ");
 } return $result;
 }

The hyperlinks pointing to the file(s) are generated just fine. The ZIP file however only contains the first file listed in the results.

How can I get the ZIP file to capture ALL the files returned?

Thanks for your input.

**PS: The new ZipArchive() library/class is not available on our production environment so I chose to use the Unix utility ZIP instead.**
