title: Multiple index variables in PHP foreach loop
body: <p>Is it possible to have a <code>foreach</code> loop in PHP with multiple "index" variables, akin to the following (which doesn't use correct syntax)?</p>
  
  <pre><code>foreach ($courses as $course, $sections as $section)
  </code></pre>
  
  <p>If not, is there a good way to achieve the same result?</p>
