Max value of max_input_vars

Question

We're using some assessments platform and we need to export results for further processing.

Platform allows export tests' results to CSV format. Problem is that it requires high max_input_vars . Current value is 1000 (in php.ini ) and we need a lot higher.

So I was wondering how high I can make max_input_vars . We're running platform on closed network, so security is not highest priority, but we need to avoid data loss or corruption.

What is max max_input_vars value or what maximum is recommended?

Answer 1

According to this it is an INT. If you're on a 64 bit system, the max value of php ints (signed) is 9,223,372,036,854,775,807. On 32 bits it's 2,147,483,648.
