title: How to transform an array using php?
body: <p>I have this array:</p>
  
  <pre><code>{"0": {"item1": "somevalue", "item2": "somevalue"}},
  {"1": {"item3": "somevalue", "item4": "somevalue"}},
  {"3": {"item5": "somevalue", "item6": "somevalue"}}
  </code></pre>
  
  <p>Using PHP, I want to convert it to this format with square brackets at the start and end and no numerical keys:</p>
  
  <pre><code>[{"item1": "somevalue", "item2": "somevalue"}},
  {{"item3": "somevalue", "item4": "somevalue"}},
  {{"item5": "somevalue", "item6": "somevalue"}}]
  </code></pre>
