使用PHP获取公交车信息的API
PHP车来了API是一个用于获取公交车信息的接口。通过这个API，我们可以获取到公交车的实时位置、预计到达时间、线路信息等数据。要使用这个API，首先需要在官网注册一个账号并获取API密钥。然后，可以使用PHP的cURL库来发起HTTP请求，将API密钥和其他参数作为请求参数发送给服务器。服务器会返回一个JSON格式的数据，我们可以通过解析这个数据来获取所需的公交车信息。在实际应用中，可以将这个API与地图服务结合，为用户提供实时的公交车位置和路线规划功能。
每天上下班都要盯着公交车的动态，很难受，所以小杰想做一个自动化获取车辆信息，并且车子快到了就及时提醒我的jio本，在忙碌几个小时之后成功提取到了车辆信息，但是自动化的工作还需要各位自己去弄一下，小杰只分享获取车辆信息的接口。
