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).
Path to the first file. This file acts as "old" file.
Path to the second file. This file acts as "new" file.
Path of the resulting patch file.
Indicates how many lines of context you want to include in diff result.
Set this parameter to TRUE
if you want to minimalize size of the result (can take a long time).
Returns TRUE
on success or FALSE
on failure.
This function doesn't work well with binary files. To make diff of binary files use xdiff_file_bdiff()/xdiff_file_rabdiff() function.
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); ?>
