使用Php格式将数据馈送到数据库中，并将该数据用于JSON格式以在D3中使用

Question

All I want to do is to get some data from JSON file for my D3.js in real time that too from user directly and get updated instantly.

There will be a php form from which data will be stored into database and the data from the database will be converted into JSON file which will be used by d3.js for some visualization technique.

Problem I am facing

I am not sure whether I can get the data from php form and convert it to JSON file instantly and can use for my Visualization model. I can convert the data into into database into JSON file but not sure how to do it one go.

Answer 1

Why you want a json file if your data is saved on database? Just json_encode($array_of_your_data_from_database) will give you a json respond easily.
