writeVarInts()

Write values using variable-length encoding (VarInt/ULEB128).


    public
                    writeVarInts(array<string|int, int> $values) : void

VarInt encoding uses the most significant bit of each byte as a continuation bit. Values are encoded in little-endian byte order with 7 bits of data per byte. Negative values are treated as unsigned 64-bit integers for proper encoding. This method handles all edge cases including overflow and ZigZag encoded values.

Parameters

$values : array<string|int, int>
