How to add/change file text with file_put_contents in the middle of content?

Question

PHP

For example, there is a json file with the following content:

[
  {
    "some": 1
  }
]

How can I change to ? "some": 1"some": 2

Answer 1

file_put_contents - writes to a file. So take what you write to a file and replace it as in normal json.

Answer 2

1. Read the file
2. Parse json
3. Change the required data
4. Convert json to a string
5. Write to file
No modification in the middle of the file will work, only overwrite the entire file. Especially json.
