By reading /usr/local/pkg/pfblockerng/pfblockerng.inc it seems a few more lines down this part might be affected as well:

    // Collect static DHCPv6 hostnames/IPs
    foreach (config_get_path('dhcpdv6', []) as $dhcpv6) {
        if (isset($dhcpv6['staticmap']) && is_array($dhcpv6['staticmap'])) {

I set up DHCP Static Mappings in the DHCP server but couldn't replicate the issue with a fresh pfBlocker installation configuring it using the Wizard.

23.05.1-RELEASE (amd64)
built on Wed Jun 28 03:57:27 UTC 2023
FreeBSD 14.0-CURRENT
pfBlockerNG-devel 3.2.0_5

Perhaps there is a specific setting in the DNS resolver to trigger this PHP error?

I do have some customizations in unbound, but they're not connected with dhcp (private-domain, local-zone, forward-zone and cache definitions). Also I didn't change them for a long time.

The Workaround works like a champ, I've been with this problem 2 weeks finding a solution, and I'm in the version 2.7.0 -> pfblockerng-devel-3.2.0_6 and I still need to do the workaround.
