Cloud Translation API不会翻译整个句子

Question

我正在尝试将英语翻译成阿拉伯语。但它只翻译一个字。 单词只会被翻译。 这是我的代码：

$curl = curl_init();curl_setopt_array($curl, array(
    CURLOPT_URL => "https://www.googleapis.com/language/translate/v2?key=".$api_key."&q=".$text."&source=".$source_language."&target=".$target_language, CURLOPT_RETURNTRANSFER => true,
    CURLOPT_ENCODING => "",
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 30,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => "GET",
    CURLOPT_POSTFIELDS => "",
    CURLOPT_HTTPHEADER => array(
    ),
    )); $response = curl_exec($curl);
    $err = curl_error($curl);

    curl_close($curl);

    if ($err) {
       echo "cURL Error #:" . $err;
    } else {
        $arr = json_decode($response,true);
        print_r($arr['data']['translations']);
        echo $response;exit;
    }
