Splitters
---------

[](#splitters)

### `RecursiveCharacterTextSplitter`

[](#recursivecharactertextsplitter)

Recursively splits text by trying a list of separators (`["\n\n", "\n", " ", ""]` by default) until each piece fits within `chunk_size`. Suitable for general text.

```
$ts = new RecursiveCharacterTextSplitter([
    "chunk_size" => 500,
    "chunk_overlap" => 50,
    "separators" => ["\n\n", "\n", " ", ""], // optional
]);
```

### `CharacterTextSplitter`

[](#charactertextsplitter)

Splits text by a single configurable separator (`"\n\n"` by default) and merges the pieces into chunks of at most `chunk_size` characters.

```
$ts = new CharacterTextSplitter([
    "chunk_size" => 500,
    "chunk_overlap" => 50,
    "separator" => "\n\n", // optional
]);
```

Running Tests
-------------

[](#running-tests)

```
composer install
vendor/bin/phpunit
```

Tests run on PHP 8.1 through 8.5 via GitHub Actions.
