xdiff_string_rabdiff — Make binary diff of two strings using the Rabin's polynomial fingerprinting algorithm
$old_data
, string $new_data
)Makes a binary diff of two strings and returns the result. The difference between this function and xdiff_string_bdiff() is different algorithm used which should result in faster execution and smaller diff produced. This function works with both text and binary data. Resulting patch can be later applied using xdiff_string_bpatch() / xdiff_file_bpatch() .
For more details about differences between algorithm used please check » libxdiff website.
old_data
First string with binary data. It acts as "old" data.
new_data
Second string with binary data. It acts as "new" data.
Returns string with binary diff containing differences between "old" and "new"
data or FALSE
if an internal error occurred.
