title: Required parameter $xxx follows optional parameter $yyy
body: <pre class="lang-none prettyprint-override"><code>Deprecated: Required parameter $xxx follows optional parameter $yyy in...
  </code></pre>
  <p>Since upgrading to PHP 8.0 this error is thrown when running code like this:</p>
  <pre class="lang-php prettyprint-override"><code>function test_function(int $var1 = 2, int $var2) {
      return $var1 / $var2;
  }
  </code></pre>
  <p>This has worked in past versions of PHP without issue.</p>
