Convert an associate array to an object?

[Robert Oschler]

With PHP 4, is there a way to convert an associative array to an object?

For example, suppose I have the following arrays inside a nested associative
array ($nestedAA):

$AA1['field1'] = 'fieldValue1';

$AA2['field2'] = 'fieldValue2';

$nestedAA['AA1'] = $AA1;
$nestedAA['AA2'] = $AA2;

I would like to take $nestedAA and convert it to an object called
$nestedObject with properties I could access like this:

echo $nestedObject->AA1->field1; # This would print 'fieldValue1'
echo $nestedObject->AA2->field2; # This would print 'fieldValue2'

How can I do this? Note, I would like a conversion method that I could use
with any nested associativee array and create the object dynamically (at
runtime).

Thanks,
Robert

Something like:

<pre>
<?php
$AA1['field1'] = 'fieldValue1';
$AA2['field2'] = 'fieldValue2';

$nestedAA['AA1'] = $AA1;
$nestedAA['AA2'] = $AA2;

var_dump($neste dAA);

function array_to_obj($a rray, &$obj)
{
foreach ($array as $key => $value)
{
if (is_array($valu e))
{
$obj->$key = new stdClass();
array_to_obj($v alue, $obj->$key);
}
else
{
$obj->$key = $value;
}
}
return $obj;
}

$nestedObject= new stdClass();
array_to_obj($n estedAA, $nestedObject);

print_r($nested Object);

echo $nestedObject->AA1->field1; # This would print 'fieldValue1'
echo $nestedObject->AA2->field2; # This would print 'fieldValue2'

?>
</pre>
