Why my server is loading these PHP variables?

Question

I'm migrating my server to a new dedicated, and after the migration my main website shows 500 Internal Error message, on error_log I see

I don't know why it is loading this many libraries, any way I can find out?

Should I just google them all and install them?

Answer 1

Look at your php.ini file; it refers to each of these libraries, or it wouldn't be trying to load them.
