WebIf the value to pack is too long, the result is truncated. If it's too long and an explicit count is provided, Z packs only $count-1 bytes, followed by a null byte. Thus Z always packs a trailing null, except when the count is 0. Likewise, the b and B formats pack a string that's that many bits long. Each such format generates 1 bit of the result.
