I have downloaded the files from https://www.gaia-gis.it/gaia-sins/windows-bin-amd64/ and moved the dll files to C:\xamppapachebin and added extension=mod_spatialite.dll to the php.ini file. This should be a simple installation however I receive the following error.

PHP Warning:  PHP Startup: Can't load module 'C:\xampp\php\ext\mod_spatialite.dll' as it's linked with 2.30, but the core is linked with 14.29 in Unknown on line 0

It appears they are using a really old version to compile these files. What can be done to remedy this issue?
