PHP 关于接收接口传递数据的问题。。

第一个字母表示类型 count表示ID数量 / 隔开 ild,ild,ild来记录数据（我是按照你的意思来）

比方

i5/1,2,3,4,5

类型为int 一共5个 分别1,2,3,4,5

其实有必要么。。。直接i:1,2,3,4,5不就行了

不一样的话这样写 i:1,2,3|s:4,5,6

懂了吗？

PHP如何写一个给外人上传数据的接口？

接口的流程.

建立控制器(访问地址)-审核访问者身份(token)-验证提交数据是否符合类型(validate

)-处理接收数据(逻辑流程)-返回结果(json字符串).

其中要注意是否存在跨域,如果跨域要做跨域处理,例如返回jsonp.

如何用PHP开发API接口

他会提供相应接口给你的，具体调用方法就相当于讲求某个链接。act=get_user_listtype=json在这里operate.php相当于一个接口，其中get_user_list 是一个API（获取用户列表），讲求返回的数据类型为JSON格式。

act=get_user_listtype=json';$ch = curl_init ();curl_setopt ( $ch, CURLOPT_URL, $url );curl_setopt ( $ch, CURLOPT_RETURNTRANSFER, 1 );curl_setopt ( $ch, CURLOPT_CONNECTTIMEOUT, 10 );curl_setopt ( $ch, CURLOPT_POST, 1 ); //启用POST提交$file_contents = curl_exec ( $ch );curl_close ( $ch );
