Description

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().

Version

PHP PECL xdiff >= 0.2.0

Return value

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