predisHow can I use the hset command in Redis with PHP?

The hset command can be used in Redis with PHP to set the value of a field in a hash stored at a key.

For example, the following code will set the field name to John in the hash stored at the key myhash:

$redis->hset("myhash", "name", "John");

The code returns 1 if the field is a new field in the hash and 0 if the field already exists in the hash.

The hset command can also be used to set multiple fields in a hash at once. The following code sets the fields name to John and age to 30 in the hash stored at the key myhash:

$redis->hmset("myhash", ["name" => "John", "age" => "30"]);

The code returns true if the fields were set in the hash.

The command can be used with the following methods in the Redis class of the phpredis library:

• hset: Set the string value of a hash field
• hmset: Set multiple fields in a hash
