<?php
class DeviceLocation {
    /**

    public static locateDevice() {

This code did not parse for me. Apparently, there is an error somewhere around this line:

Syntax error, unexpected T_STRING, expecting T_FUNCTION or T_CONST

        $geoipVersion = CONFIG['GEOIP']['version'] ?? 0;
        switch ($geoipVersion) {
            case 0:
                return(['status' => 'error', 'error' => 'Geolocation not supported']);
            case 1:
                return(self::locateDevice1());
            case 2:
                return(self::locateDevice2());
            default:
                throw new Exception("This version of GeoIP is not known!");
        }
    }
    
    private static function locateDevice1() {
        if (CONFIG['GEOIP']['version'] != 1) {
            return ['status' => 'error', 'error' => 'Function for GEOIPv1 called, but config says this is not the version to use!'];
        }
        //$host = $_SERVER['REMOTE_ADDR'];

67% of this comment could be valid code. Did you maybe forget this after debugging?
