I'm inserting a text object with a structure like this (it's a PHP object but here's what
it looks like in JSON)

  "other_details": 5,
  "phrases": [
    { "sentence": "séres humanos", "translation": "human" },
    { "sentence": "derechòs", "translation": "rights" } ]
}

Question is: what is the PHP way to iterate through $phrases and add
stick that $text_id field on there?
