Hello there and thanks,
But I am still at a loss as to what to do.
hash_file served a purpose in the php4 code below, but now it is an
official function in php5, so the below code no longer works. any
help owuld be great!
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!
Any insight would be great! I'd be willing to paypal someone. :)
How would your rewrite the above code?
Thanks!
