+     By setting the optional <parameter>preserve_keys</parameter>
+     parameter to &true;, you can force PHP to preserve the original
+     keys from the input array. If you specify &false; new number
+     indicies will be used in each resulting array with
+     indices starting from zero. The default is &false;.
