Example#1 xdiff_file_diff() example

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().
