Major new features 🚀

• Error identifiers
  • A way to categorize reported errors by a stable identifier. Up until now you had to use specific and ever-changing error messages
  • Can be used for ignoring specific errors locally with new @phpstan-ignore comment (uses current or next line automatically)
  • Can be used for ignoring specific errors in ignoreErrors section of your configuration file (phpstan.neon)
  • Can be used in output formatters
  • Can be seen in PHPStan Pro GUI or in TableErrorFormatter with -v
  • Catalogue with source code links: https://phpstan.org/error-identifiers
• PHPStan Pro Reboot
  • A new migration wizard will effortlessly migrate all your @phpstan-ignore-line and @phpstan-ignore-next-line to the new @phpstan-ignore comment style with error identifiers. The old comment style is dangerous because it ignores all errors, current and future, on that line.
  • Revamped UI for much more comfortable viewing and browsing of reported errors
  • The new UI also lets you browse ignored errors, from ignoreErrors, from your baseline and also ignored locally in source code using comments
  • Streaming errors during launch: You don't have to wait for the analysis to complete, you can see errors as they come in during the analysis
  • Support for mapping file paths to the host filesystem when running in Docker or remotely
  • Try it out by running PHPStan with --pro CLI option
• PHPDoc tags describing callable lifecycle: @param-immediately-invoked-callable, @param-later-invoked-callable
  • Useful for exception analysis (https://phpstan.org/blog/bring-your-exceptions-under-control) and @phpstan-pure
• PHPDoc tag @param-closure-this to describe what $this is bound to in a passed closure
• Two new config options around stricter offset checks in arrays (#3028), #7553, thanks @​ttomdewit!
  • reportPossiblyNonexistentGeneralArrayOffset
  • reportPossiblyNonexistentConstantArrayOffset
  • Learn more in the documentation

Bleeding edge 🔪

• Checking truthiness of @phpstan-pure above functions and methods
• Check new/function call/method call/static method call on a separate line without any side effects even without @phpstan-pure PHPDoc tag on the declaration side
  • phpstan/phpstan-src@281a87d
  • #3020, thanks @​staabm!
  • #3022, thanks @​staabm!
  • #3023, thanks @​staabm!
• BetterNoopRule - take advantage of impure points (phpstan/phpstan-src@a647052), #10389
• Run missing type check on @param-out (phpstan/phpstan-src@56b2002)
• CallToConstructorStatementWithoutSideEffectsRule - report class with no constructor (phpstan/phpstan-src@b116d25)
• Deprecated: returning plain strings as errors, use RuleErrorBuilder
  • Learn more: Using RuleErrorBuilder to enrich reported errors in custom rules
• Deprecated: returning RuleError without identifier (phpstan/phpstan-src@969e6fa)

If you want to see the shape of things to come and adopt bleeding edge features early, you can include this config file in your project's phpstan.neon:
