10 Awesome things that most people won't notice in PHP
summary
Quick practical tour of ten underused PHP functions with concrete code and version notes: demos show checkdnsrr used to partially validate email domains, extract to import array keys to variables (with flags and WordPress usage), usort for custom last‑name sorting, plus func_get_args, getenv versus $_SERVER, glob with braces, error_get_last, serialize/json, checkdate and levenshtein. Examples run live and return real outputs, the talk cites minimum PHP versions and edge cases so viewers know what will work in their environment.
