I'm having difficulty caching an array of SimpleXMLElement objects. It's the apc_store line that fails, and I'm not sure why.
The program terminates at this line, which is strange because I've used this elsewhere --- wrapping an array in a ArrayObject and storing it in the cache.
My code extract is below:
$feed = /* some url */
$xml = simplexml_load_file($feed);
$items = $xml -> xpath('/rss//item');
foreach($items as $item){
$item -> addChild('myTag1', "My Tag 1");
$item -> addChild('myTag2', "My Tag 2");
}
apc_store($feed, new ArrayObject($items), 60);
I don't think my log file is working correctly, this is the last entry, just in case it helps but I think it's to do with SSL and not helpful here:

Thanks for all your help.
In the example above, $feed was not a string representation of a url; it was an array, whose first element was a string representation of a url. Also, in addition, I was using namespaces so ArrayObject needed a slash prefix.
