Source of phpinfo fields

Question

Is there a way to know where is set a given PHP config property?

When I run phpinfo() I get a list of properties with values, example:

max_input_time 60 120

Here I know that the actual value of max_input_time is 120.

Is there a way to know where this values was set? global php.ini? local php.ini? hardcoded?

Answer 1

There is no way to differentiate if an option was set via ini_set, .htaccess php_value or php.ini.
