PHP WDDX: Struct Element

Web Distributed Data Exchange Step By Step tutorial - Part 6: in WDDX scope, it is like array but only for string-based indexes (if numeric-based, we use array element). Hope, it is simple to understand. Look following sample:

If we want to write:

$students = array('stud1'=>'Ilmia','stud2'=>'Aqila','stud3'=>'Imanda');

We can write:

<wddxPacket version='1.0'>
  <header />
  <data>
    <var name="students">
      <struct>
	    <var name="stud1">
	      <string>Ilmia</string>
	    </var>
	    <var name="stud2">
	      <string>Aqila</string>
	    </var>
	    <var name="stud3">
	      <string>Imanda</string>
	    </var>	  
      </struct>
	</var>
  </data>
</wddxPacket>
