Answer 1

Getting useful data out of the JSON response
Once you have a working URL that dumps the required JSON data, it's very easy. PHP offers built-in functions for processing and dealing with JSON data. In this case, you want to decode the JSON data into a usable format, such as an array or object.
Converting the JSON response to an array
To get it into an array, you can simply do:
$arr = json_decode(file_get_contents('http://example.com/foo.json'), 1);
Knowing the structure of the array
Now in order to work with the array, you will have to know how it is structured. For that purpose, you can use the debugging function print_r():
echo '<pre>' . print_r($arr, 1) . '</pre>';
Traversing the array to extract information
Once you know the structure of the JSON data, you can traverse it using a foreach loop:
foreach ($arr as $key => $value) {
// Do more stuff with $value
}

Answer 2

You can make a request with PHP, for example using file_get_contents() and then echo the result into JavaScript. You can then use JavaScript to extract the information you need and generate an alert.
Simplified example:
<?php
$url = 'http://api-url...';
$response = file_get_contents($url);
$data = json_decode($response, true);
$coordinates = $data['geocoding_results']['COORDINATES'];
?>
<script>
var coordinates = <?php echo json_encode($coordinates); ?>;
alert(coordinates.latitude + '; coordinates.longitude);
</script>
