Parse a dynamic JSON object into PHP - php

Question

Below is the JSON object I am trying to parse. It its basically the answers to a dynamic form. I know I can convert it to an array and then work with it. The issue I am having is the JSON object will be different every time.
{
"sections": [
{
"elements": [
{
"element": "greeting",
"components": {
"paragraph": {
"content": "Thank you for calling company name. This is a test call."
}
}

}
}
},
{
"element": "custom-message",
"components": {

},
"message": {
"name": "3[custom-message][message]",
"type": "text",

{
"element": "radio",
"components": {
"label": {
"content": "Whats type of office are you looking for?"
},
"radiolist": [
{
"input": {
"value": "value_0",
"id": "single_choice_answer_0"
},
"label": {
"content": "Dedicated Space"
}
},
{
"input": {
"value": "value_1",
"id": "single_choice_answer_1"
},
"label": {
"content": "Parttime Space"
}
}
],
"single_choice_answer": {
"value": "value_0",
"name": "4[radio][single_choice_answer]",
"required": ""
},
"help_text": {
"content": ""
}
}
}
],
"faqs": [
{
"question": "Should i have a FAQ?",
"answer": "Yes, this will help the agent to have a fluent conversation with the caller."
}
]
}
]
}
So, for example a part of the JSON object looks like the following.
"components": {
"label": {
"content": "Whats type of office are you looking for?"
},
"radiolist": [
{
"input": {
"value": "value_0",
"id": "single_choice_answer_0"
},
"label": {
"content": "Dedicated Space"
}
},
{
"input": {
"value": "value_1",
"id": "single_choice_answer_1"
},
"label": {
"content": "Parttime Space"
}
}
],
"single_choice_answer": {
"value": "value_0",
"name": "4[radio][single_choice_answer]",
"required": ""
},
I would like to take that and do something like the following:
{
"components": {
"label": {
"content": "Whats type of office are you looking for?"
},
"answer": {
"value": "value_0",
"name": "Dedicated Space",
"required": ""
}
}
Really I just need the form questions and answer formatted a little nicer in a JSON object. However, I'm not sure how to code this in PHP.
