The following code makes unified diff of two php files.

<?php

$old_version = 'my_script.php';

$new_version = 'my_new_script.php';



xdiff_file_diff($old_version, $new_version, 'my_script.diff', 2);

?>

Note:

This function doesn't work well with binary files. To make diff of binary files use xdiff_file_diff_binary().
