Twilio and PHP?

我希望这里有很多Twilio开发人员和PHP脚本编写人员。。。我正在尝试编辑一个基本的Twimlet FindMe，我真的被卡住了一段时间。。。我找不到任何关于编辑它的线索，我确实认为Twimlets有很多用处，应该更多地记录下来，因为许多初学者都把它作为起点。就我的情况而言，我需要帮助编辑以下来源的Twimlet，这样我就可以手动添加我想拨打的电话号码，直到其中一个人接听为止。。当前代码使用输入框来收集我不想使用的信息。。我花了很多时间试图让它发挥作用，但我被卡住了。。。。我试着删除REQUEST并在其中输入数字，但没有成功，而且我是Twilio的初学者，所以我需要帮助。非常感谢。
