Working with line delimited JSON strings in PHP

Question

I am using an API which requires I send it data as new line delimited JSON, for example;

{"id":"67523", "name":"Jason"}
{"id":"69928", "name":"Doug"}

The API accepts single JSON objects, but can accept multiple new line delimited JSON objects in a single batch (more efficient). How do you construct string objects like the above in PHP?

If taking a string like {"id":"67523", "name":"Jason"} , I can json_decode() it to turn it into an associative array (this is accepted by the API endpoint). However, the only way I can see to pass a number of these objects together is within an array, but the API does not accept an array of JSON objects.

Answer 1

If API really accepts newline delimited objects, and manage objects over json level, try:

$data = '{"id":"67523", "name":"Jason"}'."\r\n".'{"id":"69928", "name":"Doug"}';

In php also you can use new lines just inside string code.

Answer 2

You would want to json_encode each individual object/array. However, you can do this in such a way that you don't have to concat each individual object.

$a = ['id' => 67523, 'name' => 'Jason'];
$b = ['id' => 69928, 'name' => 'Doug'];

echo implode("\r\n", array_map('json_encode', [$a, $b]))

Output:

{"id":67523,"name":"Jason"}\r\n
{"id":69928,"name":"Doug"}

Answer 3

JSON does not allow real line-breaks.
As you said API is accepting Single Objects and not accepting an array of JSON objects, the below Code will help you somewhat where each object is given index

{
  0: {
    "id": "67523",
    "name": "Jason"
  },
  1: {
    "id": "69928",
    "name": "Doug"
  }
}
