Getting data from nested arrays in json with php - php

Question

I have my json from a url feed. Here's a sample below. I'm not doing the foreach loop correctly is the problem

Here's my php code so far. I've tried quite a few different things. I normally use xml feeds which seem to be easy for me to setup for what I need. I'm not sure what I'm missing here.
$url = 'https://whatever.com/api/external/v4/widget?userId=whatever&tag=featured'; // path to your JSON file
$data = file_get_contents($url); // put the contents of the file into a variable
$performers = json_decode($data, true); // decode the JSON feed
foreach ($performers as $performer) {
$info = $performer[0]["username"];
echo $info;
}
I'm only getting the first username and then error messages.
Warning: Illegal string offset 'username' in /whatever
Can anyone help with this?

You should use $performers['models'] array in foreach and then get username it will work fine try the following code
$performers = json_decode($data, true);
if(isset($performers['models'])){
foreach ($performers['models'] as $performer) {
$info = (isset($performer["username"])) ? $performer["username"] : '';
echo $info;
echo "<br>";
}
}
Output
model1
model2
