Constitution (v3.0.0) edition

Rule phpdoc_to_return_type

EXPERIMENTAL: Takes @return annotation of non-mixed types and adjusts accordingly the function signature. Requires PHP >= 7.0.

Warning

Using this rule is risky.

This rule is EXPERIMENTAL and [1] is not covered with backward compatibility promise. [2] @return annotation is mandatory for the fixer to make changes, signatures of methods without it (no docblock, inheritdocs) will not be fixed. [3] Manual actions are required if inherited signatures are not properly documented.

Configuration

scalar_types

Fix also scalar types; may have unexpected behaviour due to PHP bad type coercion system.

Allowed types: bool

Default value: true
