title: How to reset indexes in array_diff result?
body: <p>I have two arrays: <code>Array ( [0] =&gt; 2 [1] =&gt; 3 )</code> and <code>Array ( [0] =&gt; 2 )</code>.</p>
  
  <p>I want to get the value, which is not in second array. So I have used the <code>array_diff</code> function  but my result will get  <code>Array ( [1] =&gt; 3 )</code> 
   Actually this is the result. But a small problem here, its position is (key) <code>1</code>. I want the result in to a new array starts from 0th position, i.e., <code>Array ( [0] =&gt; 3 )</code>.</p>
  
  <p>How can I achieve this?</p>
