The file defines some of my own functions, like these:
function clean_html ($dirty) {
$dirty=strip_tags($dirty);
$clean=htmlentities($dirty);
return $clean;
}
function clean_mysql ($dirty) {
$dirty=str_replace ("--", "", $dirty);
$dirty=str_replace (";", "", $dirty);
$clean=mysql_real_escape_string($dirty);
return $clean;
}
I use these functions in many places, so I simply put them all in a
file and include it in each page.

I suppose that it could, by checking the return of one of the two
functions above. Lucky for me, I always use UTF-8 so I won't get stuck
connecting with one encoding yet doing mysql_real_escape_string with
another, which would be a problem if I had to deal with multiple
encodings.
