The MongoDB\BSON\Int64 class

Introduction

BSON type for a 64-bit integer. When decoding BSON to PHP data, this class is used when a 64-bit integer cannot be represented as a PHP integer on 32-bit platforms. These objects support overloaded arithmetic, bitwise, and comparison operators.

When working with raw BSON data through the MongoDB\BSON\Document, MongoDB\BSON\PackedArray, and MongoDB\BSON\Iterator classes, any 64-bit integer will be returned as an instance of this class, regardless of platform and whether the value can be represented as a PHP integer. This ensures that values can be roundtripped without changing the type.

During BSON encoding, objects of this class will convert back to a 64-bit integer type, even when the value would fit in a 32-bit integer. This allows explicitly storing values as 64-bit integers in BSON.
