> Affects Versions: 0.10.0
> Environment: Linux 4.13.3-1-ARCH
> PHP 7.1.10
> Reporter: Josip Sokcevic
> Assignee: James E. King, III

> This happens when using php extension. thrift_protocol_write_binary will check Z_TYPE_P of spec and expects to be array (IS_ARRAY). However, PHP7 will set it as reference (IS_REFERENCE).
> Example:
> {code}
> $s = new Serializer\TBinarySerializer();
> // Foo is a Thrift type class
> class FooExtended extends Foo {}
> $o = new Foo();
> $o2 = new FooExtended();
> // this works just fine:
> $s->serialize($o); // this uses thrift_protocol_write_binary if available
> // Next line throws \Thrift\Exception\TProtocolException if thrift_protocol_write_binary is used
> // However, it doesn't break if no extension is available.
> $s->serialize($o);
> {code}
> Proposed solution is to dereference using ZVAL_DEREF before checking types (attached). Alternative would be to mark struct type classes as final, but that break compatibility.
