socket - PHP中如何保存资源类型?
<code>目前在写一个小项目。本人只是一个前端工程师,现在临时写一个PHP脚本。 流程是前端发送数据到服务器,然后服务器通过socket通信发送数据到设备上,然后再依次从设备发送到前端。 目前数据交互功能已经完成。但是有一个数据是需要频繁从设备发送到前端的, 所以我们希望在 服务器和设备的通信是时刻保持畅通的,这样就能避免每次发送消息都要`socket_creat(),socket_connect()` 。 我起初的想法是将创建的$socket 用session保存起来。但是发现session是不能保存资源类型的。 所以在此想向各位大神请教一下,如何将资源类型保存下来,或者有什么好方法能避免每次发送消息都得创建socket。</code>

不能保存资源类型,资源类型只是一个引用,引用的对象没了你保存这个引用本身也没意义。
你的需求看得不是很明白,如果是要实现一个socket server
可以使用开源方案(如Workerman
, Swoole
)或者自己写。
官方有个简单的例子参考一下:

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4.
