This article mainly introduces how to solve the problem of arrays in AJAX requests. The article provides detailed sample code. I believe it will be helpful for everyone's understanding and learning. Friends in need will follow the editor. Let's see. Hope it helps everyone.
Everyone should have discovered that when we send an AJAX request with an array in the data, it cannot be directly placed in the data and sent to the background like ordinary JSON data.
For example There is such a data that needs to be sent to the background:
{ "orderId": 22, "resourceJson": [ { "carCapacity": 223, "carNumber": "123", "driverInfo": "123", "failReason": "3123123", "id": 25, "ispass": 0, "lineId": 784, "load_plan": "123", "onPackageDay": 123, "price": 123, "storeOutCapacity": 123, "store_out_capacity": 123 }, { "failReason": "31231231", "id": 2, "ispass": 0, "lineId": 787, "load_plan": "123", "store_out_capacity": 123, "tallyman": "ddd" }, { "failReason": "123123", "id": 1, "ispass": 0, "lineId": 785, "load_plan": "123", "store_out_capacity": 123, "tallyman": "fff" } ] }
The resourceJson field is an array. If you directly send this JSON data to the background
The data obtained in the background looks like this:
#The browser will automatically decompose the array into variables, and it will be stupid to get this data in the background. .
So, the best way is to program the array into a string. It is very simple. Store the array in a separate variable, and then JSON.stringify
(array), convert the resulting string Put it into JSON data, so that the browser will not automatically deconstruct the array for you, and what you get in the background is a real array.

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.
