title: Having the variable names in func_get_args()
body: <p>As this function can take unknown numbers of parameters:</p>
  
  <pre><code>function BulkParam(){
      return func_get_args();
  }
  </code></pre>
  
  <p>A <code>print_r</code> will print only the values, but how i can retrieve the variable names as well as the array key? For example:</p>
  
  <pre><code>$d1 = "test data";
  $d2 = "test data";
  $d3 = "test data";
  
  print_r(BulkParam($d1, $d2, $d3));
  </code></pre>
  
  <p>It will print this:</p>
  
  <pre><code>Array
  (
      [0] =&gt; test data
      [1] =&gt; test data
      [2] =&gt; test data
  )
  </code></pre>
  
  <p>But i want to have the variables name as the index name or key name of all arrays. Then the array would look like this:</p>
  
  <pre><code>Array
  (
      [d1] =&gt; test data
      [d2] =&gt; test data
      [d3] =&gt; test data
  )
  </code></pre>
