xdiff_file_patch -- Patch a file with an unified diff

## Description

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;
}
?>`
