The code that I gave should be in a separate file (del.php) and should NOT be
incorporated into edit.php as you have tried to do below.

If you want to combine the functionality of edit.php and del.php into a single
page then the easiest way is to place this code at the beginning:
if (isset($_GET['action']) && $_GET['action'] == 'del' &&
!empty($_GET['id'])) {
$news=file("this.txt");
$fp = fopen('outputfile', 'w');
foreach ($news as $line) {
if (strpos($line, $_GET['id']) !== 0) {
fwrite($fp, $line);
}
}
fclose($fp);
}
Then follow it with your original edit.php, BUT replace this link:
<a href=del.php>DELETE THIS LINE</a>
with
<a href="edit.php?action=del&id=$id">DELETE THIS LINE</a>
