title: make object from two arrays with the seperate arrays as properties
body: <p>I have a <code>PHP</code> function that give me two seperate JSON arrays (array1 and array2). How can I merge them in an object with properties, like this:</p>
  
  <pre><code>{
    "array1": [ {"type": "column", "valueField": ..., "descriptionField": ..., }]
    "array2": [ {"type": "column", "valueField": ..., "descriptionField": ..., }] 
  }
  </code></pre>
  
  <p>Thanks in advance</p>
