predisHow can I use the PHP Redis HDEL command to delete a key?

The PHP Redis HDEL command can be used to delete a key from a hash. To use the command, the key and the name of the hash must be provided.

For example:

$redis->hdel('myhash', 'mykey');

This will delete the key mykey from the hash myhash.

The parts of the command are:

• $redis->hdel: the HDEL command
• 'myhash': the name of the hash
• 'mykey': the key to delete

No output is returned when the command is successful.
