Im running USBWebserver v8.6 on a USB drive on a windows 10 machine, I need to update PHP to run Mautic and it requires PHP version 5.6.19 while my USB server has PHP Version 5.4.17. I tried to download windows version and extract it to the PHP folder on the drive and did a restart on the web server but that did not work.
I don't know how to update the PHP please help.
Did you change the httpd.conf file in the Settings folder?
Almost at the end of that file there are these lines:
Change these values according the PHP installation you want. Let me know if this works for you. I got this information from the documentation on how to install PHP.
