Описание

mixed xdiff_file_patch ( string file, string patch, string dest [, int flags] )

xdiff_file_patch() patches file file with unified patch in file patch and stores result in file dest.

flags can be either XDIFF_PATCH_NORMAL (default mode, normal patch) or XDIFF_PATCH_REVERSE (reversed patch).

Returns FALSE if an internal error happened, string with rejected chunks of patch or TRUE if patch has been successfully applied.

Пример 1. xdiff_file_patch() example The following code applies unified diff to a file. <?php $old_version = 'my_script-1.0.php'; $patch = 'my_script.patch'; $errors = xdiff_file_patch($old_version, $patch, 'my_script-1.1.php'); if (is_string($errors)) {    echo "Rejects:\n";    echo $errors; } ?>

Пример 2. Patch reversing example The following code reverses a patch. <?php $new_version = 'my_script-1.1.php'; $patch = 'my_script.patch'; $errors = xdiff_file_patch($new_version, $patch, 'my_script-1.0.php', XDIFF_PATCH_REVERSE); if (is_string($errors)) {    echo "Rejects:\n";    echo $errors; } ?>
