/**
 * UploadedFile represents the information for an uploaded file.
 *
 * You can retrieve the set of an uploaded file from application 'request' component:
 *
 * ```php
 * $uploadedFiles = Yii::$app->request->getUploadedFiles();
 * ```
 *
 * You can use [[saveAs()]] to save file on the server.
 * You may also query other information about the file, including [[clientFilename]],
 * [[tempFilename]], [[clientMediaType]], [[size]] and [[error]].
 *
 * For more details and usage information on UploadedFile, see the [guide article on handling uploads](guide:input-file-upload)
 * and [PSR-7 Uploaded Files specs](http://www.php-fig.org/psr/psr-7/#16-uploaded-files).
 *
 * @property string $clientFilename the original name of the file being uploaded.
 * @property int $error an error code describing the status of this file uploading.
 * @property int $size the actual size of the uploaded file in bytes.
 * @property string $clientMediaType  the MIME-type of the uploaded file (such as "image/gif").
 * Since this MIME type is not checked on the server-side, do not take this value for granted.
 * Instead, use [[\yii\helpers\FileHelper::getMimeType()]] to determine the exact MIME type.
 * @property string $baseName Original file base name. This property is read-only.
 * @property string $extension File extension. This property is read-only.
 * @property bool $hasError Whether there is an error with the uploaded file. Check [[error]] for detailed
 * error code information. This property is read-only.
