I have 5 meta values for each WordPress post and I’m using ACF for creating meta fields. I want to have just 1 meta value stored in DB instead of 5. I know it should be serialized but I don’t know how to achieve this, using ACF. Here is an example of what I want:

meta_key: some_example
meta_value: a:3:{s:10:"some_value";s:13:"another_value";s:17:"yet_another_value"}
