Today, I would like to propose three articles that do not talk about WordPress. But they are about its engine, PHP. PHP 8.1 is out these days, doing my usual research I found this wonderful article that summarizes all the changes. And since reading is like cherries, I found two other programming gems that I hope you like them. As usual, I report the links at the end of the message. --- IT --- Oggi, vi vorrei proporre tre articoli che non parlano di WordPress. Ma trattano del suo motore, PHP. In questi giorni è uscito PHP 8.1, facendo le miei solite ricerche ho trovato questo splendido articolo che riassume tutte le modifiche. E visto che la lettura è come le ciliege ho scovato altre due chicche di programmazione che spero vi piacciano. Come al solito riporto i link a fine messaggio. --- Link --- (PHP 8.1: What's New and Changed) - https://php.watch/versions/8.1 (PHP Hash Algorithm Benchmark) - https://php.watch/articles/php-hash-benchmark (Writing better Regular Expressions in PHP) - Writing better Regular Expressions in PHP Happy coding
