I have built a 'standard' dual-interface COM dll. Most functions return data as a 1 dimmension SafeArray of VARIANTs. I get the following when I try:

$jReader = new COM("journalmancom.reader") or die("Unable to instantiate JournalManCOM object");

$var = new VARIANT();
$jReader->GetPrimaryEventTypes( $var );
print $var->value;


Warning: Unsupported variant type: 8204 (0x200C)

This corresponds to VT_VARIANT | VT_ARRAY. I noticed that php_variant_to_pval() doesn't look for VT_ARRAY.
