🚀 #PHPStan 2.3.0 is out and up to 7.5× faster than ten months ago. Analysing the #WordPress codebase dropped from 60.5s in December 2025 to 7.9s on an M1 Pro MacBook #PHP #staticanalysis #opensource ⚡ PHPStan Turbo reimplements hot parts of the analyser in #Cpp, forks workers instead of spawning them and registers an #OPcache optimizer pass that strips runtime type checks. Turbo now makes PHPStan almost 60% faster. The .so/.dll files ship inside the #Composer package and are enabled automatically 💾 Warm result cache on #Drupal: no changes 1.6s, 10 changed files 2.8s, 10% of the project 6.2s, full run 22s. Composer dependency updates and #Symfony DI container changes no longer wipe the whole cache. New extension APIs let custom extensions describe precisely which files to invalidate. Monorepos with Composer path repositories and scanDirectories/scanFiles setups are now handled properly 🧬 Generics: bidirectional type narrowing analyses code around new Collection(...) multiple times and infers the template type from how the object is used. Scalars are no longer generalized (1 stays 1, not int). Closes 17 issues at a 1-3% performance cost. Funded by the #SovereignTechFund 🔍 Unused variable detection with five core rules: variable.unused, assign.unused, assign.overwritten, assign.redundant and the data-flow based assign.unusedFlow. It also covers array offsets never read, foreach keys and values, ++/-- results, catch variables, closure use variables and unused parameters of functions and private methods 🧠 The same engine infers closure types from usages without any PHPDocs, including by-reference variables, and infers static variable types from assignments instead of falling back to mixed 🏗️ Under the hood: a single-pass inside-out engine rewrite replaces three separate AST traversals. Code like $a = [$b = 1, $b + 1] now infers as array{1, 2}. Extension APIs stay compatible; the new features require bleeding edge 🔌 Released alongside: phpstan-strict-rules, phpstan-symfony and phpstan-phpunit 2.1.0 🌐 phpstan.org/blog/phpstan-2-3…
