Using this rule is risky¶

This rule is EXPERIMENTAL and [1] is not covered with backward compatibility promise. [2] @param 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.

scalar_types¶

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

Allowed types: bool

Default value: true

Example #1¶

Default configuration.

--- Original
+++ New
 <?php

 /**
  * @param string $foo
  * @param string|null $bar
  */
-function f($foo, $bar)
+function f(string $foo, ?string $bar)
 {}

Example #2¶

With configuration: ['scalar_types' => false].

--- Original
+++ New
 <?php

 /** @param Foo $foo */
-function foo($foo) {}
+function foo(Foo $foo) {}
 /** @param string $foo */
 function bar($foo) {}
