Finally, after hours of strugling, I finished installing PHP 7.02 on our IIS 7.5 Windows Server 2008. All functions properly except for one error:

[20-Jan-2016 15:19:26 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'D:\PHP\php-7.0.2-nts-Win32-VC14-x64\ext\php_mysql.dll' - The specified module could not be found. in Unknown on line 0

When checking the downloaded zip-file op PHP 7.02 it's clear that the folder ext doesn't contain a file called php_mysql.dll.

So my question is where can we get this file to avoid this error?

Thanks to the comment of Naruto I figured out that the dynamic loading of all the modules in the php\ext folder wasn't the culprit. Because the file php_mysql.dll wasn't in that folder, so it couldn't be loaded from there. After further analyses it seems that in the latest PHP (7.02) download for Windows 64-bit the php.ini file still contains this:

[PHP_MYSQL]
extension=php_mysql.dll

After commenting out the section the error in the log file was gone. As we obviously can't load that dll file anymore.

;[PHP_MYSQL]
;extension=php_mysql.dll
