# sebastian/diff
Diff implementation for PHP, factored out of PHPUnit into a stand-alone component.
## Installation
You can add this library as a local, per-project dependency to your project using [Composer](https://getcomposer.org/):
composer require sebastian/diff
If you only need this library during development, for instance to run your project's test suite, then you should add it as a development-time dependency:
composer require --dev sebastian/diff
### Usage
The `Differ` class can be used to generate a textual representation of the difference between two strings:
```php
use SebastianBergmann\Diff\Differ;
$differ = new Differ;
print $differ->diff('foo', 'bar');
```
The code above yields the output below:
--- Original
+++ New
@@ @@
-foo
+bar
The `Parser` class can be used to parse a unified diff into an object graph:
```php
use SebastianBergmann\Diff\Parser;
use SebastianBergmann\Git;
$git = new Git('/usr/local/src/money');
$diff = $git->getDiff(
'948a1a07768d8edd10dcefa8315c1cbeffb31833',
'c07a373d2399f3e686234c4f7f088d635eb9641b'
);
$parser = new Parser;
print_r($parser->parse($diff));
```
The code above yields the output below:

[from:SebastianBergmann\Diff\Diff:private] => a/tests/MoneyTest.php
