xdiff_file_diff — Make unified diff of two files
Beschreibung
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).
Parameter-Liste
- old_file
Path to the first file. This file acts as "old" file.
- new_file
Path to the second file. This file acts as "new" file.
- dest
Path of the resulting patch file.
- context
Indicates how many lines of context you want to include in diff result.
- minimal
Set this parameter to TRUE if you want to minimalize size of the result (can take a long time).
Rückgabewerte
Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.
Beispiele
Beispiel #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);
?>Anmerkungen
Hinweis: This function doesn't work well with binary files. To make diff of binary files use xdiff_file_bdiff()/xdiff_file_rabdiff() function.
