Php. ini, how to restore the default value after another period of time

Php. ini is configured to restore the default environment after a period of time: wampserver recently encountered a very strange problem in php. after the following values are redefined by ini, upload_max_filesize = 256Mpost_max_sizemax_executio php. the default value of ini is restored after another period of time.
Environment: wampserver
Recently, I encountered a strange problem.

After I redefine these values in php. ini
Upload_max_filesize = 256 M
Post_max_size
Max_execution_time
Max_input_time
Memory_limit

After two days, all configurations will be restored to the default value, for example, upload_max_filesize = 2 M...


Does anyone know why?

Besides, if I had an outfit, I would have known it.

------ Solution --------------------
Search all php. INI files. There may be more than one. One of them is copied from the other. I remember this.
We recommend that you modify both or change the suite.
------ Solution --------------------
This is definitely not the configuration file you saw for the first time. it was changed or changed...
------ Solution --------------------
Enable phpinfo. php to check whether the php. ini file is in the directory you see, or if you have multiple php. INI files.
