title: array_push is couting the value instead of adding
body: <p>When I insert the value to the array its counting the value instaed of adding. </p>
  
  <p>I have the below array named $staff_group_arr</p>
  
  <pre><code>Array ( [0] =&gt; All Rights User [1] =&gt; Operation [2] =&gt; Supritendent [3] =&gt; Admin Department [4] =&gt; Accounts [5] =&gt; Transportation )
  </code></pre>
  
  <p>I am donig like this </p>
  
  <pre><code>$glo_staff_array = array_push($staff_group_arr, "Global", "Managers");
  
  print_r($glo_staff_array );
  </code></pre>
  
  <p>Result is coming as 8</p>
