I am using phpMyAdmin version 4.2.11. At the time of writing my tab, my Status tab is as follows (several options are expanded, pay attention to "Current Settings", bottom right):

Note that there are no direct visible βfunctionsβ that allow things like slow_query_log be slow_query_log . So, I went on the Internet because user-oriented answers will only be relevant to a specific release and therefore will quickly become outdated. So what will you do if not see the corresponding answer above?
As explained in the article, you can run a global query to enable or disable slow_query_log et al. Requests to enable and disable these logs are not complicated, so do not be afraid of them, for example.
SET GLOBAL slow_query_log = 'ON';
From here, phpMyAdmin is very useful, and a little googling will help you quickly and quickly. For example, after executing the above request, I can return to the "Instructions / Settings" option in the "Status" window of the Monitor and see this (pay attention to further instructions):
