Unfortunately `VEMB` has a unique `RESP2` reply as far as I can tell,
where it sends the embedding mode (int8, bin, fp32) as a simple string.
This would cause any of PhpRedis' generic reply handlers to turn that
into `true` which isn't useful. For that reason we need a custom reply
handler.
Additionally slightly rework `VINFO` to short circuit and return failure
if we read anything other than a bulk string or an integer reply type.
Otherwise we may get out of sync on the socket.
See #2543
All of these commands have the same form `<cmd> key`. `VINFO` is a bit
of an outlier however that uses simple strings as opposed to bulk
strings for the key names, meaning we had to create a custom handler.
See #2543
This is likely to never happen but just skipping NULL nodes is better than aborting the reset.

This command is similar to `VADD` in that it's pretty simple but allows
for a great many options.
In it's most basic form:
```php
// To get similarity of a different element
$redis->vsim('myvec', 'some-element');
// To get similarity for a vector of scores
```
As seen above the method attempts to infer element or vector from the
argument passed to $member`. However, since we do serialize the member
when doing `ELE` mode, the user can also specify `ELE` explicitly in the
options array to force an `ELE` search sending serialized values.
```php
$redis->setOption(Redis::OPT_SERIALIZER, Redis::SERIALIZER_PHP);
$redis->vsim('myvec', [3.14, 2.71], ['ELE']);
```
See #2543
This is for Redis 8.0's vector sets.
The command itself can be quite complex with all of the various options but
pretty simple using all defaults.
```php
$redis->vadd('myvec', [3.14, 2.17], 'myelement');
```
The implementation takes a default argument `$options` which can be an array in
order to specify the myriad of other knobs users can send. We just do a bit of
validation on inputs (e.g. certain numeric options must be positive) and make
sure the command is constructed in a valid way (e.g. REDUCE <dim> must come
before the floating point values).
By default we deliver `FP32` blobs but allow the user to send `VALUES` in the
options array which will cause PhpRedis to send N individual values. Sending
values is slower but might be nice for debugging (e.g. watching monitor)

* Rework HMGET and implement HGETEX
Instead of using a bespoke NULL terminated `zval**` array for the
context array we can use a `HashTable`. This might be a tiny bit more
expensive but Zend hashtables are quite efficient and this should also
be less error prone.
* Rework our `HashTable` context array to store keys
Instead of sending an array of values we can instead add the fields as
keys to our context array. That way when we combine the keys with the
Redis provided values we can do it in-place and then just give the
HashTable to the user to then do with what they want.
* Implement HGETDEL command.
* Fix edge cases to abide by legacy behavior.
Previously we coerced integer strings into integer keys when zipping
`HMGET` responses. This commit adds logic so we continue to do this and
do not change semantics.
* Implement `HGETDEL` and `HGETEX` for `RedisCluster`.
This commit implements the new commands and reworks the `HMGET` reply
handler to use the new context `HashTable`.
* Fix an edge case where we get zero multiblk elements
* Tests for `HGETEX` and `HGETDEL`
* Minor logic improvement
We don't need to check if `c->reply_len > 0` in the last else block
since we have already determined it must be.
* Implement `HSETEX` for `Redis` and `RedisCluster`
* Use `zval_get_tmp_string` ro populating non-long keys
* Adds `GETEX` to the README.md documentation.
* Allow the user to send `PERSIST` either as an array key or just in the
array, to conform with similar methods.
* Implement getEx for `RedisCluster`
Fixes#2512
When a node timeout occurs, then phpredis will try to connect to another
node, whose answer probably will be MOVED redirect. After this we need
more time to accomplish the redirection, otherwise we get "Timed out
attempting to find data in the correct node" error message.
Fixes#795#888#1142#1385#1633#1707#1811#2407
We also need to update the `RedisCluster` logic to handle very large
curosr values, in addition to handling them for the `Redis` and
`RedisArray` classes.
See #2454, #2458
* Use our `redis_cmd_append_sstr_key_*` and `redis_cmd_append_sstr_zval`
wrappers, which handle key prefixing and serialization transparently.
* Rework ZADD so it can handle the bulk double response from the `INCR`
options.
* Implement `ZDIFF`, `ZINTER`, `ZUNION`, `ZMSCORE`, and
`ZRANDMEMBER` for `RedisCluster`.
* Refactor `ZUNIONSTORE` command and switch to using our centralized
zset option parsing handler.
See #1894
* Create inline wrappers of the low-level php_stream_* functions that
also keep track of the number of bytes written/read.
* Change the logic to aggregate network traffic until the user
explicitly "resets" it. I think this will be a more common use-case
(running many commands and then seeing overall network IO).
See #2106
- Finish adding docblocks with examples for all of the stream commands.
- Fix XAUTOCLAIM response handler (the reply has a slightly different
structure to XCLAIM.
