## Property details

### $data <span id="property-data"></span>

```php
public array<string, array<string, mixed>> $data = []
```

The data rows.

Each array element represents one row of data (column name => column value).

## Method details

### load() <span id="method-load"></span>

```php
public function load(): mixed
```

Loads the fixture.

The default implementation simply stores the data returned by [`getData()`](/docs/api/yii/test/arrayfixture/index.md#method-getData) in [`$data`](/docs/api/yii/test/arrayfixture/index.md#property-data).
You should usually override this method by putting the data into the underlying database.

**Returns**

`mixed`

### unload() <span id="method-unload"></span>

```php
public function unload(): mixed
```

Unloads the fixture.

This method is called after every test method finishes.
You may override this method to perform necessary cleanup work for the fixture.

**Returns**

`mixed`

### getData() <span id="method-getData"></span>

```php
protected function getData(): array<string, array<string, mixed>>
```

Returns the fixture data.

The default implementation will try to return the fixture data by including the external file specified by [`$dataFile`](/docs/api/yii/test/filefixturetrait/index.md#property-dataFile).
The file should return the data array that will be stored in [`$data`](/docs/api/yii/test/arrayfixture/index.md#property-data) after inserting into the database.

**Returns**

`array<string, array<string, mixed>>`: The data to be put into the database

**Throws**

- [`yii\base\InvalidConfigException`](/docs/api/yii/base/invalidconfigexception/index.md): if the specified data file does not exist.
