Heres my code:
<!-- coded by ScHmIdTy, for jonnyli -->
<?php
$fn = "test.txt";
$file = fopen($fn, "a+");
$size = filesize($fn);
if($_POST['addition']) fwrite($file,", " . $_POST['addition']);
$text = fread($file, $size);
fclose($file);
?>
<form action="<?=$PHP_SELF?>" method="post">
<textarea><?=$text?></textarea><br/>
<input type="text" value="Ban" id="Ban" name="addition" onclick="document.getElementById('Ban').value='';return false;"/>
<input type="submit"/>
<input name="text" value="Un-Ban" id="Un-Ban" name="clear" onclick="document.getElementById('Un-Ban').value='';return false;"/>
<input type="submit"/>

Have you ever looked into creating a MySQL database, and not using a text file? In almost every situation that would be a much better idea. Then, to delete it, you'd just do a mysql delete query and delete the entry.

As suggested above, using a MySQL database would be a better option. It will be easier to retrieve, insert, update and delete information. Especially when files are starting to get big.
Anyway, on your current situation, you could retrieve the file, use the str_replace() function to look for a pattern and replace it with something else (or nothing, thus removing it).
Setting up a MySQL database is far from difficult. Same goes for using it in your script. With Object Oriented PHP you can easily prepare and execute queries protected against sql-injections. If you need help, let me know.
