- Validate that all values passed are valid IPv6 addresses.
- Fail compilation if any value fails this check.
- The following values will pass:
- $my_ip = "3ffe:505:2"
- validate_ipv6_address(1)
- validate_ipv6_address($my_ip)
- validate_bool("fe80::baf6:b1ff:fe19:7507", $my_ip)
- The following values will fail, causing compilation to abort:
- $some_array = [ true, false, "garbage string", "1.2.3.4" ]
- validate_ipv6_address($some_array)
- ENDHEREDOC
