Rule `phpdoc_to_property_type`¶

Takes @var annotation of non-mixed types and adjusts accordingly the property signature. Requires PHP >= 7.4.

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 @var annotation is mandatory for the fixer to make changes, signatures of properties without it (no docblock) will not be fixed. Manual actions might be required for newly typed properties that are read before initialization.

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
 class Foo {
     /** @var int */
-    private $foo;
+    private int $foo;
     /** @var \Traversable */
-    private $bar;
+    private \Traversable $bar;
 }

Example #2¶

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

--- Original
+++ New
 <?php
 class Foo {
     /** @var int */
     private $foo;
     /** @var \Traversable */
-    private $bar;
+    private \Traversable $bar;
 }

Example #3¶

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

--- Original
+++ New
 <?php
 class Foo {
     /** @var int|string */
