mixed xdiff_file_patch (string $file, string $patch, string $dest, [int $flags = DIFF_PATCH_NORMAL]) DESCRIPTION
Patches a $file with a $patch and stores the result in a file. $patch has to be an unified diff created by xdiff_file_diff(3)/xdiff_string_diff(3) function. An optional $flags parameter specifies mode of operation. PARAMETERS
o $file - The original file. o $patch - The unified patch file. It has to be created using xdiff_string_diff(3), xdiff_file_diff(3) functions or compatible tools. o $dest - Path of the resulting file. o $flags - Can be either XDIFF_PATCH_NORMAL (default mode, normal patch) or XDIFF_PATCH_REVERSE (reversed patch). Starting from version 1.5.0, you can also use binary OR to enable XDIFF_PATCH_IGNORESPACE flag. RETURN VALUES
Returns FALSE if an internal error happened, string with rejected chunks if patch couldn't be applied or TRUE if patch has been success- fully applied. EXAMPLES
