Phpstan array

It has a point of course, purely from static analysis it cannot reliably be inferred that c diabolikdvd always be of the string[] type - the phpdoc typehint declares phpstan array could be a string as well some day, phpstan array. In my practical case however, due to the definition of the API I'm calling, I cannot know define undefined slope that a and b are the only string keys, only that all non- c keys will be string keys with string values. Array shape does, phpstan array, to my knowledge, not support any definition for unknowns, for example the following are all unacceptable:. See lines 20 and

Learn more about PHPDoc basics ». You can! Check out Stub Files ». PHPStan has a concept of implicit and explicit mixed. Missing typehint is implicit mixed - no type was specified as a parameter type or a return type. Explicit mixed is written in the PHPDoc. Rule level 9 is stricter about the mixed type.

PHPStan 1. My role has shifted from the main code contributor to quality assurance, project vision [1] , and taking care of the continuous integration pipeline. At the current rate of quality pull requests from rvanvelzen1 markusstaab and herndlm I might just rename my job title to "green button pusher". This feature was developed by Richard van Velzen. After generics and conditional return types PHPStan continues to democratize its advanced features. Besides arguments, it also supports narrowing types of properties and returned values from other methods on the same object. Learn everything about this new feature in the documentation ». List in PHPStan is an array with sequential integer keys starting at 0 and with no gaps. It joins many other advanced types expressible in PHPDocs :. We had to go through all of those and decide:. If you want to try it now, include bleedingEdge. This feature was developed by Markus Staab. So if a parameter is assigned by reference, the type after the function call is always mixed :. The type of a mutable object can change after calling a mutating method.

In some cases PHPStan knows about the literal value of an expression. Some types exist to only consist of other types learn more about union vs. This table describes which implementation is used for different bounds the X in template T of X :. Following list is by no means complete, please see the interface code for more details. The describe method returns a string representation description of the type, which is useful for error messages.

PHP 8 is just around the corner! PHPStan is ready to analyse your codebases that will be taking advantage of the latest features in the coming weeks and months. Make sure you have PHPStan 0. Ambitious language feature from PHPStan contributor Ilija Tovilo that aims to be a better alternative to a switch statement. Arms also might not be executed if one of the arms is a catch-all because the comparison will be always true. Since PHPStan knows enough information about the code, it can detect it as well. I hope that this feature will lead to using more advanced types in PHPDocs , which in turn will actually lead to more type safety PHPStan will point out wrong values going into the function at the callsite :. They will make function calls with multiple arguments more clear [1].

This page is about all the configuration options PHPStan has. A config file can be passed to the phpstan executable using the -c --configuration option:. When using a config file, you have to pass the --level -l option to analyse command default value 0 does not apply here , or provide it as a level parameter in the config file itself. Learn more about other command line options ». If you do not provide a config file explicitly, PHPStan will look for files named phpstan. The usual practice is to have phpstan.

This visual image of overlapping circles tells us how isSuperTypeOf always responds. Because in runtime T might contain something that falls inside the E circle like InvalidArgumentException or something that falls outside of the E circle like TypeError. This feature was developed by Richard van Velzen. These relationships work between all types, as long as you imagine the circles correctly. The type of a mutable object can change after calling a mutating method. Generics » , Generics By Examples ». Edit this page on GitHub. For example StringType returns 'string'. Skip to content. PHPStan has a concept of implicit and explicit mixed. This is useful when solving undefined variables. The closest I'd like are probably:. It allows to represent key-value pairs backed by an array:. For example FloatType also accepts IntegerType.

I am wondering whether there is a way, I can create a Type from within a ReturnTypeExtension so phpstan gets aware of this "polymorphic" Row class. Beta Was this translation helpful?

It has a point of course, purely from static analysis it cannot reliably be inferred that c will always be of the string[] type - the phpdoc typehint declares it could be a string as well some day. Some functions accept a bitmask composed by -ing different integer values. Give feedback. Available in PHPStan 1. A string can be a callable. Edit this page on GitHub. For example StringType returns 'string'. In some cases PHPStan knows about the literal value of an expression. Types in non-canonical form can and should be simplified.
