How can Webservices be utilized to exchange data between PHP scripts on different servers?

To exchange data between PHP scripts on different servers, you can utilize Webservices. Webservices allow communication between different applications over a network, enabling data exchange in a standardized way. By creating a Webservice on one server and consuming it in another PHP script on a different server, you can easily exchange data between them. 

// Example of creating a Webservice in PHP

// Webservice script on Server A
// This script fetches data from a database and returns it as JSON

// Connect to the database
$pdo = new PDO('mysql:host=serverA;dbname=mydatabase', 'username', 'password');

// Fetch data from the database
$stmt = $pdo->query('SELECT * FROM mytable');
$data = $stmt->fetchAll(PDO::FETCH_ASSOC);

// Return data as JSON
header('Content-Type: application/json');
echo json_encode($data);
```

```php
// Example of consuming a Webservice in PHP

// Webservice consumer script on Server B
// This script consumes the Webservice from Server A and processes the data

// Call the Webservice URL
$webservice_url = 'http://serverA/webservice.php';
$data = file_get_contents($webservice_url);

// Decode the JSON data
$data = json_decode($data, true);

// Process the data
foreach ($data as $row) {
    // Process each row of data
    echo $row['column1'] . ' - ' . $row['column2'] . '<br>';
}
