Further to this I have been examining the Code to try and get at a property to see if it already exists:
I see this in: abstract class Zend_View_Helper_Placeholder_Container_Standalone
/**
* Overloading: retrieve property
*
* @param string $key
* @return mixed
*/
public function __get($key)
{
$container = $this->getContainer();
if (isset($container[$key])) {
return $container[$key];
}
return null;
}
However as the Container is a sequential object it would be lucky to get the property I want based on the key wouldn't it as I need to pass in an int value
Zend_View_Helper_Placeholder_Container Object
( [0] => stdClass Object ( [type] => name [name] => title
[content] => Content. [modifiers] => Array ( ) ) [2] =>
stdClass Object ( [type] => name [name] => keywords [content]
=> keywords [modifiers] => Array ( ) ) [3] =>
stdClass Object ( [type] => name [name] => description [content]
=> description [modifiers] => Array ( ) )
)
What i want is the property based on the name.
Sorry if I am missing a trick here but just need to see if Description is already set if it is then do not set again.

I would have thought though that there can only be one Description so I need to do
// Layout Call
if ($config->meta->description) {
$this->headMeta()->setName('description', $config->meta->description);
}
// View Call
$this->headMeta()->setName('description', 'Words words words.');
Trouble is the Layout call is getting processed afterwards and overwriting my view call - can I check if something exists in the array first and then decide to call the layout setName?

You can *clear* what's in the array by passing an empty array to
exchangeArray(), as the containers extend ArrayObject:
$this->headMeta()->exchangeArray(array());
$this->headMeta()->setName('description', 'Words words words.');
