<p>Here are some examples of PHP code from Drupal core:</p>
<pre><code class="php">/**
* The weight of this role in administrative listings.
*
* @var int
*/
protected $weight;
</code></pre>
<pre><code class="php">/**
* Path of the image file.
*
* @var string
*/
protected $source = '';
</code></pre>
<pre><code class="php">/**
* Alter the list of mail backend plugin definitions.
*
* @param array $info
* The mail backend plugin definitions to be altered.
*/
</code></pre>
<p>These use some of the standard PHPDoc types of <code>int</code>, <code>string</code> and <code>array</code>.</p>
<p>Although they are comments, docblocks are checked by static analysis tools like PHPStan to parse the code and report any potential errors.</p>
<p>If you want to go deeper, PHPStan has <a href="https://phpstan.org/writing-php-code/phpdoc-types">its own PHPDoc types</a> that you can use to add more information and context.</p>
<p>Instead of specifying an argument must be a <code>string</code>, you can specify it's a <code>non-empty-string</code> or a <code>class-string</code>.</p>
<p>You can specify whether an integer is a <code>positive-int</code> or <code>negative-int</code>, or within a certain range.</p>
<p>You can define the shape of an array or object, whether an array is empty, or the types of keys and values in an array.</p>
<p>All of this is used by PHPStan when analysing the code and will give better results and find more potential bugs before anyone else does.</p>
