  <para>
   This function sorts an array such that array indices maintain their
   correlation with the array elements they are associated with. This is used
   mainly when sorting associative arrays where the actual element order is
   significant. Array elements will have sort order according to current
   locale rules.

   Equivalent to standard PHP
   <function>asort</function>.
