*
* The primary purpose of this option is to make it more ergonomic when

* Note: This option incurs a small performance penalty when reading data
* because we have to see if the data is a string representation of an int
* or float.
*
* @example
* $redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_IGBINARY);
* $redis->setOption(Redis::OPT_PACK_IGNORE_NUMBERS, true);
*
* $redis->set('answer', 32);

* | OPT_SERIALIZER | enum | Set the automatic data serializer.<br>`Redis::SERIALIZER_NONE`<br>`Redis::SERIALIZER_PHP`<br>`Redis::SERIALIZER_IGBINARY`<br>`Redis::SERIALIZER_MSGPACK`, `Redis::SERIALIZER_JSON`|

* | OPT_COMPRESSION_LEVEL | int | Set a specific compression level if Redis is compressing data. |
* | OPT_NULL_MULTIBULK_AS_NULL | bool | Causes PhpRedis to return `NULL` rather than `false` for NULL MULTIBULK replies |
