title: PHP array mapping
body: <p>Is there a cleaner way than <code>foreach</code> to get an array of all "label" values?</p>
  
  <pre><code>$methods[0]['label'] = 'test';
  $methods[0]['nr']    = 99;
  $methods[1]['label'] = 'whatever';
  $methods[1]['nr']    = 10;
  
  
  foreach($methods as $method) {
      $methodsLabel[] = $method['label'];
  }
  </code></pre>
