	<input type="file" name="photo[]" />
	<input type="file" name="photo[]" />
	<input type="submit" value="上传" />
</form>

$len = count($_FILES['photo']['name']);
for ($i = 0; $i < $len; $i++) {
	$file = [
		'name' => $_FILES['photo']['name'][$i];
		'type' => $_FILES['photo']['type'][$i];
		'tmp_name' => $_FILES['photo']['tmp_name'][$i];
