在PHP中，如何检测输入变量是否因超过max_input_vars而被截断？(In PHP, how can I detect that input vars were truncated due to max_input_vars being exceeded?)

我知道E_WARNING是由PHP生成的

PHP警告：未知：输入变量超过1000

但是我如何在脚本中检测到这一点？

I know that an E_WARNING is generated by PHP

PHP Warning: Unknown: Input variables exceeded 1000

But how can I detect this in my script?

最满意答案

一个“足够接近”的方法是检查if( count($_POST, COUNT_RECURSIVE) == ini_get("max_input_vars"))

如果POST变量的数量恰好处于极限，这将导致误报，但考虑到默认限制为1000，则不太可能成为问题。

A "close enough" method would be to check if( count($_POST, COUNT_RECURSIVE) == ini_get("max_input_vars"))

This will cause a false positive if the number of POST vars happens to be exactly on the limit, but considering the default limit is 1000 it's unlikely to ever be a concern.
