Simple routine to convert a get_defined_vars object to XML.



<?php

function obj2xml($v, $indent='') {

  while (list($key, $val) = each($v)) {

    if ($key == '__attr') continue;

    // Check for __attr

    if (is_object($val->__attr)) {

      while (list($key2, $val2) = each($val->__attr)) {

        $attr .= " $key2=\"$val2\"";

      }

    }

    else $attr = '';

    if (is_array($val) || is_object($val)) {

      print("$indent<$key$attr>\n");

      obj2xml($val, $indent.'  ');

      print("$indent</$key>\n");

    }

    else print("$indent<$key$attr>$val</$key>\n");

  }

}



//Example object

$x->name->first = "John";

$x->name->last = "Smith";

$x->arr['Fruit'] = 'Bannana';

$x->arr['Veg'] = 'Carrot';

$y->customer = $x;

$y->customer->__attr->id='176C4';



$z = get_defined_vars();

obj2xml($z['y']);

?>



will output:

<customer id="176C4">

  <name>

    <first>John</first>

    <last>Smith</last>

  </name>

  <arr>

    <Fruit>Bannana</Fruit>

    <Veg>Carrot</Veg>

  </arr>

</customer>
