Input variables exceeded 1000 when submitting php post
When submitting a post, if the array is too large, this may occur:
<code>Unknown: Input variables exceeded 1000. To increase the limit change max_input_vars</code>
The solution is: open php.ini and modify the parameters
max_input_vars = 1000;
Change the default 1000 to a larger value.
Seems like a simple question. But if you receive post request users and the server environment is various, you can't let everyone who uses your service change this parameter.
So, I processed the post array with json_encode and base64 first. It was sealed into a parameter, but it took 0.3 seconds for the server to parse these arrays. It cost 100 times more than before. This still feels inappropriate. And if memory_limit is set too small, it will prompt insufficient memory.
Both options have their own shortcomings.
If it were you, how would you deal with this problem?

I choose the second option, json transmission.
First of all, I don’t know how you calculated that json parsing is 0.3 seconds slower than post parsing. That is, how do you know how long it takes to parse a post?
Secondly, compared to form-data, the json format is more customizable and has better support for lists, objects, etc. Making good use of these things can greatly reduce the size of the transferred data.

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. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,
