get data json print php

You can use the file_get_contents() function. It would look something like:

$conteudo = file_get_contents('https://api.findmespot.com/spot-main-web/consumer/rest-api/2.0/public/feed/0ozWRQqxiMnv5bqJzSUIMyUIIbMGrP5qu/message.json');
echo $conteudo;

Since it is a JSON, we can transform it into an object using the json_decode($conteudo) function. If you want to see the exact format of JSON you can use the following code

echo '<pre>';
print_r($conteudo);
echo '</pre>';

Now that you already have the content in an object, we can make a foreach to go through all JSON content

foreach ($conteudo->response->feedMessageResponse->messages->message as $key) {
    print_r('Latitude: '.$key->latitude);
    echo ' - ';
    print_r('longitude: '.$key->longitude);
    echo '<br>';
}

The complete code looks like this:

$conteudo = json_decode(file_get_contents('https://api.findmespot.com/spot-main-web/consumer/rest-api/2.0/public/feed/0ozWRQqxiMnv5bqJzSUIMyUIIbMGrP5qu/message.json'));
foreach ($conteudo->response->feedMessageResponse->messages->message as $key) {
    print_r('Latitude: '.$key->latitude);
    echo ' - ';
    print_r('longitude: '.$key->longitude);
    echo '<br>';
}
