Need clarification of installing php_mysql.dll php_mysqli.dll simultaneously

According to the PHP Manual,

"If you would like to install the mysql extension along with the
mysqli extension you have to use the same client library to avoid any
conflicts."

I find this confusing because I have two dll libraries installed on my
Windows XAMP system:

(1) php_mysql.dll
(2) php_mysqli.dll

I seem to be able to use functions from both of these libraries, so I
am confused as to what the PHP manual is saying.

They're the _extension DLLs_. The _client DLL_ is libmysql.dll, which will be
loaded by both.

On Windows it's basically a non-issue, since both will load the same
libmysql.dll (it would take some runtime fiddling with PATH or explict paths
compiled in to get one extension to load a different libmysql to the other).

On UNIX it may well be possible to statically link one extension against a
different MySQL client to the other, or even have both dynamically load
different ones - you'd still have to deliberately mess it up, but it's more
possible, hence the warning.
