hello there,
hash_file means something new in php5, and it seems to of broken my
code:
function hash_file ($strFilename) {
$n = 0;
for ($posFilename = strlen($strFilename) -1; $posFilename >= 0;
$posFilename-- ) {
$n *= 2;
if ($n & 4096) { $n |= 1; }
$n ^= (ord($strFilename[$posFilename])*11);
$n &= 4095;
}
return sprintf ("%02o/%02o", ($n/64) & 63 , $n&63);
}
For now, the error that I get with the above code is just:
PHP Fatal error: Cannot redeclare hash_file()
Is there some way to rewrite the above code, or something to
substitute for hash_file? Thanks!
The original coder also wrote this comment with the code:
// Don't even ask me how this works. Apparently it creates a
register for the filenme
// by xoring the characters into a number from right to left. The
top six bits and the
// bottom six bits are returned as the path name. I didn't write it
though, I just
// converted it from a perl function that I found in the pair
Networks private newsgroups.

Thanks for your help!
