crc32

I've patched original crc32 PHP function to allow incremental crc32 counting. It touches only a few lines of original code. New crc32 function signature is int crc32(string str [,int prev_sum]) With this patch you can generate crc32 checksum for even large files without reading it contents to single variable. Fe. instead of doing | $file_string = file_get_contents($file); $crc = crc32($file_string); | you can do $crc=0; $f =fopen($file,'r'); while ( $data=fread($f,1024)) $crc = crc32($data,$crc); fclose($f); Icremental processing has less memory requirements. I'd like also change base64_* functions to allow incremental processing. Any chances apply such changes ? Regards, Wojtek
