Makes an unified diff containing differences between old_file and
new_file and stores it in dest file. The
resulting file is human-readable. An optional context parameter
specifies how many lines of context should be added around each change.
Setting minimal parameter to true will result in outputting the shortest
patch file possible (can take a long time).

Esempi
Example #1 xdiff_file_diff() example
The following code makes unified diff of two php files with context length of 2.
<?php
$old_version = 'my_script.php';
$new_version = 'my_new_script.php';
xdiff_file_diff($old_version, $new_version, 'my_script.diff', 2);
?>Note
Nota:
This function doesn't work well with binary files. To make diff of binary files use xdiff_file_bdiff()/xdiff_file_rabdiff() function.
