说明

xdiff_file_patch ( string $file , string $patch , string $dest [, int $flags = DIFF_PATCH_NORMAL ] ) : mixed

The unified patch file. It has to be created using xdiff_string_diff(), xdiff_file_diff() functions or compatible tools.

dest

Starting from version 1.5.0, you can also use binary OR to enable XDIFF_PATCH_IGNORESPACE flag.

返回值
