PHP 错误 : Function name must be a string/Undefined Variable send_sms

Question

if(!empty($_GET['new_time'])){

    $sql2 = "SELECT * FROM ".$table_name." WHERE id=".$_GET['new_time'];
    $result2 = mysqli_query($conn, $sql2);
    $rows = mysqli_fetch_assoc($result2);
    $mobile_number = $rows['mobile_number'];
    // Create instance with key
    $key = 'AIzaSyD1tPfs4s2dYYHMkCOqNZoVsTkDyud-9Yg';
    $googer = new GoogleURLAPI($key);


    $message = lang_content(98, $rows['preferred_language'])." ".$shortDWName;
    $send_sms($mobile_number,$message,$city_id);
}

如果有人触发了 new_time，我会得到这个错误。

send_sms is a function to send a message.

Answer 1

调用该函数时不需要在函数名中添加$:

只需使用send_sms($mobile_number,$message,$city_id);
