xdiff_file_rabdiff — Make binary diff of two files using the Rabin's polynomial fingerprinting algorithm
bool xdiff_file_rabdiff ( string $old_file , string $new_file , string $dest )
Makes a binary diff of two files and stores the result in a patch file. The difference between this function and xdiff_file_bdiff() is different algorithm used which should result in faster execution and smaller diff produced. This function works with both text and binary files. Resulting patch file can be later applied using xdiff_file_bpatch()/xdiff_string_bpatch().
For more details about differences between algorithm used please check » libxdiff website.
Retorna TRUE em caso de sucesso ou FALSE em falhas.
