method.void

Code example

<?php declare(strict_types = 1);

class Foo
{
	public function doFoo(): void
	{
	}
}

$foo = new Foo();
$result = $foo->doFoo();

Why is it reported?

The return value of a method that returns void is being used. A void return type indicates that the method does not return a meaningful value. Using the result of such a call is a logic error because the value is always null.

How to fix it

Do not use the return value of a void method:

 <?php declare(strict_types = 1);

 $foo = new Foo();
-$result = $foo->doFoo();
+$foo->doFoo();

If you need the method to return a value, change its return type.
