xdiff_string_rabdiff

(PECL xdiff >= 1.5.0)

Make binary diff of two strings using the Rabin's polynomial fingerprinting algorithm

string xdiff_string_bdiff ( string $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.

Parameters:

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:

Returns string with binary diff containing differences between "old" and "new" data or FALSE if an internal error occurred.
