Create Functions in php to split info from multidimensional arrays to save it to a DB

I need to extract info from a large multidimensional arrays, the info is located on [login to view URL] . This is the repository: [login to view URL] I need the info of [login to view URL] file. For example, [login to view URL] have 540 records, but have different levels like id, name, bio, terms (this can have one or more). I need to extract all the info from "id" and save it to a table and then extract all the info from "name" and save to other table and the same for the others but maintaining the relation, the identifier is going to be bioguide. Some levels can have more fields, example: on name some can have "first, last, official_full" but some other person could have "first, middle, last, official_full" same apply for the other levels. If you need more info about, let me know and send me your proposal. Thanks
