使用情景:
1:餐厅在地图上画一个多边形,以表示所能配送的范围(餐厅是云图上的PIO);
2:用户打开应用后,定位;
3:自动匹配当前位置可以送餐的餐厅(即用户位置在餐厅配送区域内)
我看了一下API好像实现不了我要的功能,API所实现的功能是:
1:以用户定位点为基准,根据城市范围,检索的关键字,检索周围多少千米的PIO (其实就是周边圆形检索)
2:多边形检索其实就是上面的变种,由polygon请求参数定义多边形;
所以这样就实现不了我要的效果了,看了百度地图也是这样的。
如果要实现我要的效果,只能这样:
1:餐厅的云图数据中应该有polygon这样的字段,这个数据是我画出来的。
2:用户定位。
3:将用户的经纬度传给云图检索API,API中利用polygon来进行计算,返回polygon字段可以覆盖当前用户位置的餐厅。
也就是说,原有的模式就反过来了,有API端利用polygon来检索范围,而不是用户画一个地址,检索地址内的PIO;
找了好久,貌似高德,百度等地图的API都不可能实现我要的效果。
请各位大神帮我看看谢谢了。

Arrays can be stored in PHP sessions. 1. Start the session and use session_start(). 2. Create an array and store it in $_SESSION. 3. Retrieve the array through $_SESSION. 4. Optimize session data to improve performance.

PHP session garbage collection is triggered through a probability mechanism to clean up expired session data. 1) Set the trigger probability and session life cycle in the configuration file; 2) You can use cron tasks to optimize high-load applications; 3) You need to balance the garbage collection frequency and performance to avoid data loss.

Tracking user session activities in PHP is implemented through session management. 1) Use session_start() to start the session. 2) Store and access data through the $_SESSION array. 3) Call session_destroy() to end the session. Session tracking is used for user behavior analysis, security monitoring, and performance optimization.

Using databases to store PHP session data can improve performance and scalability. 1) Configure MySQL to store session data: Set up the session processor in php.ini or PHP code. 2) Implement custom session processor: define open, close, read, write and other functions to interact with the database. 3) Optimization and best practices: Use indexing, caching, data compression and distributed storage to improve performance.

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

The session realizes user authentication through the server-side state management mechanism. 1) Session creation and generation of unique IDs, 2) IDs are passed through cookies, 3) Server stores and accesses session data through IDs, 4) User authentication and status management are realized, improving application security and user experience.
