#!/usr/bin/php -q
<?PHP
$contents=file_get_contents("file.txt");
preg_replace('^A-Za-z','',$contents);
file_put_contents("file.txt",$contents);
?>
you need to make sure you have the [] around your characters like this:
preg_replace('[^A-Za-z]','',$contents);
and you might need to extend that regex out some...do you have a data example.
