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.

Przykład 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;

                }

                
?>

Przykład 2. Patch reversing example

<?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;

                }
