Hi,

The "file" command on unix should tell you if the file is text or
binary.

You could also do it with a regexp:

$isBinary = preg_match('/[^\x08\t\n\r\f\x20-\x7e]/',
file_get_contents('/the/file'));

(By the way, less can be made to stop warning you by using the -f
option: less -f /usr/local/bin/php)
