取消设置所有POST数据 - PHP

Will unset($_POST) remove all POST variables in PHP?

Or do you have to go one by one using unset($_POST['varname']) ?

I would try setting it instead:

$_POST = [];

That said, IMO it's generally a bad practice to directly modify PHP's Super Global arrays, but whatever.

Unsetting might work, I assume you tried it as it's trivial to do. I myself have never tried unsetting it, so who knows it might just work....
