PHP array to JSON encoded string - php

Question

I want JSON in below format, from PHP array,
How should I write PHP array and How should I convert it to JSON to get specific output in below format
{
"value": [
"01GQSE92030S8MNA78WQZ09JJQ",
"{\n\"user_id\": \"{{current_user.id}}\",\n\"user_phone\": \"{{current_user.phone}}\",\n\"ticket_id\": \"{{ticket.id}}\",\n\"ticket_comment\": \"{{ticket.latest_comment}}\",\n\"ticket_comment_author\": \"{{ticket.latest_comment.author.name}}\",\n\"organization_id\": \"{{ticket.organization.external_id}}\",\n\"organization_name\": \"{{ticket.organization.name}}\",\n\"requester_name\": \"{{ticket.requester.name}}\",\n\"requester_phone\": \"{{ticket.requester.phone}}\"\n}"
]
}
I tried below PHP array with json_encode, but output is not in required format,
array(
"value" => "01GQSE92030S8MNA78WQZ09JJQ",
array(
"user_id" => "{{current_user.id}}",
"user_phone" => "{{current_user.phone}}",
"ticket_id" => "{{ticket.id}}",
"ticket_comment" => "{{ticket.latest_comment}}",
"ticket_comment_author" => "{{ticket.latest_comment.author.name}}",
"organization_id" => "{{ticket.organization.external_id}}",
"organization_name" => "{{ticket.organization.name}}",
"requester_name" => "{{ticket.requester.name}}",
"requester_phone" => "{{ticket.requester.phone}}",
"agent_external_id" => "{{current_user.external_id}}",
"ticket_external_id" => "{{ticket.external_id}}",
"customer_external_id" => "{{ticket.requester.external_id}}"
)
);

You need to encode the second entry array to JSON, also in your desired output is need to show the \n, so add second parameter JSON_PRETTY_PRINT in json_encode here is the code.
<?php
$array = [
"value" => [
"01GQSE92030S8MNA78WQZ09JJQ",
json_encode([
"user_id" => "{{current_user.id}}",
"user_phone" => "{{current_user.phone}}",
"ticket_id" => "{{ticket.id}}",
"ticket_comment" => "{{ticket.latest_comment}}",
"ticket_comment_author" => "{{ticket.latest_comment.author.name}}",
"organization_id" => "{{ticket.organization.external_id}}",
"organization_name" => "{{ticket.organization.name}}",
"requester_name" => "{{ticket.requester.name}}",
"requester_phone" => "{{ticket.requester.phone}}",
"agent_external_id" => "{{current_user.external_id}}",
"ticket_external_id" => "{{ticket.external_id}}",
"customer_external_id" => "{{ticket.requester.external_id}}",
],JSON_PRETTY_PRINT),
],
];
print_r(json_encode($array,JSON_PRETTY_PRINT));
