Fragmenting incoming data with PHP Json - php

Question

The form of the incoming json data:
{
"statusCode": 200,
"message": "success",
"result": [
{
"longitude": -87.06687,
"start_location_latitude": 20.63589,
"start_location_longitude": -87.06687,
"end_location_latitude": 20.63589,
"end_location_longitude": -87.06687,
"highlights": [
{
"title": "Oh Yes...Mezcal Shots",
"url": "https://phoenix-cdn.azureedge.net/phoenix-blob-public-exps/1396_Mezcal_Shot.jpg"
},
{
"title": "Playa Del Carmen Beachfront",
"url": "https://phoenix-cdn.azureedge.net/phoenix-blob-public-exps/1396_Playa_Del_Carmen-Beach_Punta_Esmeralda.jpg"
},
{
"title": "Visit the Market",
"url": "https://phoenix-cdn.azureedge.net/phoenix-blob-public-exps/1396_Playa_Del_Carmen.jpg"
}
]
}
]
}
This incoming data is combined into a single line.

But what I want to do is to get the first 4 of these data, for example, by throwing them into separate variables and using them. However, I was never able to do that.
My code:
foreach($UnlockData as $highlights)
{
foreach($highlights as $SingleImage)
{
if(strlen($SingleImage['url']) > 3) {
echo $SingleImage['url'];
}
}
}

Answer 1

This will return the first 4 highlights from each entry in result. I am using the json object vs array because I find using it as objects makes for easier to read code.
<?php
$json = json_decode($incomingJSON);
foreach ($json->result as $result) {
$ctr = 0 ;
foreach($result->highlights as $highlight) {
if (strlen($highlight->url) < 5) continue;
echo "<P>" . $highlight->title. " - " . $highlight->url;
$ctr ++;
if ($ctr>3) break;
}
}

Answer 2

If there is ever only one result then just get all the url from highlights (not clear why the strlen):
$urls = array_column($array['result'][0]['highlights'], 'url');
foreach($urls as $url) {
if(strlen($url) > 3) {
echo $url;
}
}
If there are multiple result then get all the highlights and then get all the url from that:
$urls = array_column(array_column($array['result'], 'highlights'), 'url']);
