This should b really easy but I can’t find reference – easy points for someone!

I have an option in my wp_options table, and need to set it via update_option(). I just can’t find the correct syntax for doing something similar to the following where I update the key object_key in the option my_plugin_settings where this is an option in my wp_options table:


update_option('my_plugin_settings[object_key]','new value');


How is it done correctly?
