This script checks the installed php versions looking for the compatible php
32 that includes the dependencies that WordPress needs to install and run. If a
33 compatible version of php is found, but it does not have all the required
34 dependencies available, it is skipped. If a compatible version of php is
35 not found the script dies.
37 The highest version of php that matches all the prerequistes is selected. If the
38 site does not currently use this version of php, the site is updated to use it.
