What is the scope of functions such as Ini_set and putenv, or is it limited to this site?
On the official website The description of these two functions is that the modifications are valid when the script executes.
But it does not say whether this modification is valid for the site or for the global. If it is globally valid, it is not possible to modify the default global PHP security settings through these functions, resulting in security issues.
Does anyone know the scope of its function, or can it be tested in such a way that it is scoped?
Also there is no need to disable them in the disable_functions, normal Web applications to use their situation is many?

Ini_set end of script run when current script runs
Putenv survived at the end of the current session request

Valid only for the second run, like the constant you set
