MongoDB\BSON\Timestamp::getIncrement

说明

The increment component of a Timestamp is its least significant 32 bits, whichs denotes the incrementing ordinal for operations within a given second. This value is read as an unsigned 32-bit integer with big-endian byte order.

Note:

Because PHP's integer type is signed, some values returned by this method may appear as negative integers on 32-bit platforms. The "%u" formatter of sprintf() may be used to obtain a string representation of the unsigned decimal value.
