Hello. We have MediaWiki 1.26.0 and PHP that was installed about a year ago is 5.6.14. Recently we started to get a lot of PHP-related alerts as security issues on the server where Wiki is running. We think to upgrade PHP from 5.6.14 to the more recent. QUESTION: is it safe to upgrade PHP-software to the most recent one OR would you recommend to upgrade to certain version of PHP, which one? Thank you!

MediaWiki 1.26 will work with PHP 5.6, the minor version is not relevant. You can upgrade PHP to e.g. version 5.6.26. This should not cause problems.
However, MediaWiki 1.26 - at least officially - is not compatible with PHP 7. So, if you want to upgrade PHP to version 7, you will have to upgrade MediaWiki (and extensions, which you might use) to version 1.27 first.
The our server where WIkI is running has OS Windows Server 2008 R2 64-bit, from where would you recommend to install PHP 5.6.26? We looked at the web site http://windows.php.net/downloads/releases/archives/ and did not find that version. Any recommendation from where to download and install it? Thank you!
In fact, the latest version they are offering there is PHP 5.6.25 from this August.
If you want to know, why version 5.6.26 is not there (yet), you should ask the PHP guys. If someone knows, and if someone can change this, then it's them!
The latest version does not get archived. Instead, it always is available from here: http://windows.php.net/downloads/releases/
