Error "Unknown class SimpleXMLIterator" with HHVM

Question

It looks like HHVM is having trouble with SimpleXML according to

https://github.com/facebook/hhvm/issues/650

https://github.com/facebook/hhvm/issues/303

The class SimpleXMLIterator is used on our case by Amazon S3' PHP SDK. I tried the same code when HHVM is turned off and that works perfectly.

Any idea/fix to solve this? Or ways to go around it by using other XML parsing tool for S3 SDK than CFSimpleXML?

Code used:

$s3->batch()->copy_object(
                array('bucket' => $temp_bucket, 'filename' => $filename_source),
                array('bucket' => $bucket, 'filename' => $filename_dest),
                array('acl' => AmazonS3::ACL_PUBLIC)
            );

$response =  $s3->batch()->send();

Answer 1

SimpleXMLIterator will be available in next release of hhvm (probably 3.9) https://github.com/facebook/hhvm/commits/d29d110217bf3fabdc75d487f4c96740603ae2eb

Sadly SimpleXMLIterator just hasn't been implemented yet. You can either do it, or open an issue and wait for someone else to do it.
