Rule phpdoc_to_param_type¶
Takes @param annotations of non-mixed types and adjusts accordingly the
function signature. Requires PHP >= 7.0.
Warning¶
This rule is experimental¶
Rule is not covered with backward compatibility promise, use it at your own risk. Rule’s behaviour may be changed at any point, including rule’s name; its options’ names, availability and allowed values; its default configuration. Rule may be even removed without prior notice. Feel free to provide feedback and help with determining final state of the rule.
Using this rule is risky¶
The @param annotation is mandatory for the fixer to make changes, signatures
of methods without it (no docblock, inheritdocs) will not be fixed. 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
union_types¶
Fix also union types; turned on by default on PHP >= 8.0.0.
Allowed types: bool
Default value: true
Examples¶
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) {}
Example #3¶
With configuration: ['union_types' => false].
--- Original
+++ New
<?php
/** @param Foo $foo */
-function foo($foo) {}
+function foo(Foo $foo) {}
/** @param int|string $foo */
function bar($foo) {}
