What's New in PHP 8.5
summary
PHP 8.5 adds concrete, usable features: closures in constant expressions plus a pipe operator for single-argument chaining and debugger support that lets you step through pipe values; clone(object, [props]) creates modified copies while respecting visibility and readonly rules; a new URI/URL parsing classes (WG and RFC variants) with getters/setters and correct encoding; opcache becomes a built-in extension; attributes now target constants and include nodiscard; filter can throw on failure; and handy array_first/array_last and grapheme-aware string functions.
