xdiff_file_rabdiff

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

bool **xdiff_file_rabdiff** string $old_file string $new_file string $dest

Makes a binary diff of two files and stores the result in a patch file. The difference between this function and is different algorithm used which should result in faster execution and smaller diff produced. This function works with both text and binary files. Resulting patch file can be later applied using /. xdiff_file_bdiff``xdiff_file_bpatch``xdiff_string_bpatch

For more details about differences between algorithm used please check

old_filePath to the first file. This file acts as "old" file.

new_filePath to the second file. This file acts as "new" file.

destPath of the resulting patch file. Resulting file contains differences between "old" and "new" files. It is in binary format and is human-unreadable.

return.success

Voorbeeld: example

The following code makes binary diff of two archives.

<?php
$old_version = 'my_script_1.0.tgz';
$new_version = 'my_script_1.1.tgz';

xdiff_file_rabdiff($old_version, $new_version, 'my_script.bdiff');
?>

Opmerking: > Both files will be loaded into memory so ensure that your memory_limit is set high enough.
