使用 JSON 编辑 MySQL 数据库中的现有表

Question

There is a few JSON lines:

[{"id":"1","word_item":"house","word_translation":"translation1","word_language":"English","word_rank":"0"},

{"id":"26","word_item":"cat","word_translation":"translation2","word_language":"English","word_rank":"1"},

{"id":"27","word_item":"man","word_translation":"translation3","word_language":"English","word_rank":"2"},

{"id":"28","word_item":"Lorem","word_translation":"translation","word_language":"English","word_rank":"5"}]

First I get it from the server with word_rank = 0 for all the lines. After the user types in a special input the translation of the words from "word_item", js code compares the user's answer with corresponding "word_translation". Each error adds one point to the "word_rank", you can see it in the JSON above.

How can I update the table in my DB with php so that I could save new word ranks after the user answered the questoin? I mean, the user clicks the button, json changes, it is send to the server

If you have the most recent version of MySQL you can filter results with JSON_CONTAINS and you can then update JSON with JSON_SET .
