      <p>I prefer writing and working with strictly typed code.</p>

      <p>One of the major improvements in PHP has been the option to enable strict types.</p>

      <p>For example, this code will usually not error and give the result:</p>

      <pre><code class="php">function add(int $a, int $b): void
      {
          var_dump($a + $b);
      }

      add(1, '1');
      </code></pre>

      <p>However, I'd prefer if it failed as I'm passing the function an integer and a string, but specifying they should both be integers.</p>

      <p>Fixing this is simple, by adding this line to the top of the file:</p>

      <pre><code class="php">declare(strict_types=1);
      </code></pre>

      <p>I add this to every PHP file by default.</p>

      <p>I want my code to be as strict and predictable as possible, and to error when I want it to and make any bugs more explicit and easier to find and fix.</p>
