Code example

<?php declare(strict_types = 1);

/*
 * @param string $name
 * @return int
 */
function doFoo(string $name): int
{
	return strlen($name);
}

Why is it reported?

A comment contains PHPDoc tags (like @param, @return, @var, etc.) but uses /* instead of /** as the opening delimiter. PHP and PHPStan only recognize PHPDoc blocks that start with /**. A comment starting with /* is treated as a regular multi-line comment, and its type annotations are silently ignored.

This is a common typo that can cause PHPStan to miss type information that was intended to be provided.

How to fix it

Change the comment opening from /* to /**:

-/*
+/**
  * @param string $name
  * @return int
  */
 function doFoo(string $name): int
 {
 	return strlen($name);
 }
