property.uninitialized

Code example

<?php declare(strict_types = 1);

class Foo
{
	private string $name;

	public function getName(): string
	{
		return $this->name;
	}
}

Why is it reported?

The class has a typed property that is never assigned a value -- neither as a default value nor in the constructor. Accessing an uninitialized typed property in PHP causes a fatal error (Typed property must not be accessed before initialization).

This rule does not apply to readonly properties, which have their own dedicated checks.

How to fix it

Assign a default value to the property:

 class Foo
 {
-	private string $name;
+	private string $name = '';
 }

Or initialize the property in the constructor:

 class Foo
 {
 	private string $name;

+	public function __construct(string $name)
+	{
+		$this->name = $name;
+	}
+
 	public function getName(): string
 	{
 		return $this->name;
 	}
 }
