It's just a text file, so I could run sed on it, but how do you test
for just those characters?
So if I understand you have a text file and you want to remove all
characters that are not A-Z a-z ,()':.
I would do the following:
$contents=file_get_contents("file.txt");
preg_replace('[^A-Za-z\,\(\)\'\:\.]','',$contents);
file_put_contents("file.txt",$contents);
That will remove all other characters from the file. (Though you should
wait until someone else posts and fixes my regex).

Thanks for the point in the right direction at least. I can't get it to
work yet, but I'm reading up on preg_replace and am trying a bunch of
different things. Here's my CLI script as it stands right now (I took
out everything except A-Z to make sure there wasn't something weird with
the other characters going on.):
#!/usr/bin/php -q
<?PHP
$contents=file_get_contents("file.txt");
preg_replace('^A-Za-z','',$contents);
file_put_contents("file.txt",$contents);
?>
The timestamp on file.txt changes, but the text in it stays the same.
