PHPStan is on Patreon! You can show your support by backing PHPStan on Patreon. Choose your reward from different tiers and be a part of PHPStan's sustainable future development. I will deeply appreciate it. Thanks!

PHPStan now has an on-line playground over at phpstan.org! Thanks to @JanTvrdik, you can try out the static analyser right in your browser!

Major new features:

  • Parsing read-only/write-only properties with @property-read/@property-write annotations. #285 (thanks @stekycz!)
  • Checking writing to read-only properties and reading from write-only properties (level 0 for accesses on $this and level 2 for the rest). This is useful in combo with @property-read|write annotations and with custom class reflection extensions.
  • Reading and checking correctness of passed parameters to methods from @method annotations including variadic methods. #285 (thanks @stekycz!)
  • Check for duplicate keys in literal arrays (level 0)
  • Checks for invalid key types in literal arrays, in list() and short array destructuring syntax, in writing to and reading from arrays (level 3)
  • Handle fatal errors when autoloading unknown classes/interfaces/traits #255 (thanks @Majkl578) This lowers the risk of a fatal error during analysis because of an unknown class.

Enhancements:

  • For level 7 (checking possible nullables), PHPStan now considers check for truthy value as a confirmation of not-null value (if ($possibleNullable)) #278 #296 #291
  • Added Checkstyle error formatter #271
  • Getting annotation methods and properties also from interfaces #292
  • Static calls on arbitrary expressions (not just on class names) are checked on level 2 and higher
  • Separate setting to check arguments passed by reference on level 5. Use checkArgumentsPassedByReference: true in your config file if you're on a lower level and want to check this.
  • Read methods and properties from annotations also from traits
  • Checking that constructors do not return anything (returned value is silently thrown away)
  • Checking accessing properties on possible null values (level 7)
  • Types assigned to properties are checked also for assign operations like .=
  • Simpler and faster caching without dependency on nette/caching #396 (thanks @kukulich!)
  • Parsing type of variable from @var annotation with type only #395 (thanks @stekycz!)
  • TypeCombinator::combine accepts multiple types as variadic argument

BC breaks:

  • Removed support for PHP-Parser 2.x. #293 Use phpstan/phpstan-shim in case of conflicting dependencies.
  • Moved properties-related rules to PHPStan\Rules\Properties namespace. Rename the rules in case you're using completely custom ruleset (no predefined level).
  • Added isReadable/isWritable on PropertyReflection

Bugfixes:

  • Fixed mysqli::query parameters count #280
  • Fixed argument count for DateTimeZone::getTransitions() #297
  • DateInterval has microseconds since PHP 7.1 #311
  • Fixed looking for inheritDoc when the phpDoc is in an interface
  • Fixed \Locale::getDisplayLanguage() and locale_get_display_language() 2nd parameter optionality #312
  • Added first parameter to DOMDocument::saveHTML() #279
  • Find dynamic return type extensions in case the scope class name case does not match the reality
  • Fixed deleting non-existent memory limit file when the rule level is not passed as CLI option while it should
  • Changed all use of "catched" to "caught" #341
  • PHPStan does not crash on PHP 7.2 (full support coming soon)
  • Type specifier: fixed handling of nested logical operators #338
  • CallToCountOnlyWithArrayOrCountableRule: fixed union handling
  • Add better description to "call on nullable" error #282
  • Fixed internal error when analysing short array destructuring syntax from PHP 7.1 with missing item #368
  • RequireParentConstructCallRule fix: supressed constructor calls are now detected correctly #312
  • Fixed resolving variable and expression types from branches. This fixed a lot of issues in conditional code. #277 #299 #355
  • Fixed overriding specified variable type in foreach and catch
  • Fixed availability of variables in finally block defined in try and catch blocks with early termination
  • Fixed undefined variables because of other assign operations #322
  • Correct type for string with multiple parts in doublequotes #376
  • Fixed imagewebp reflection - added 3rd optional parameter #389
  • Fix "incorrect case" error when using trait aliases #391
