In what scenarios should PHP scripts be tested on different servers or environments to ensure consistent functionality?

When PHP scripts interact with external services, databases, or APIs, it is important to test them on different servers or environments to ensure consistent functionality. This is because different server configurations, network setups, or software versions can impact how the PHP script behaves. By testing on multiple environments, developers can catch any potential issues early on and ensure that the script works as expected in all scenarios. 

// Example PHP script that interacts with an external API
function fetchDataFromAPI($url) {
    // Make API request
    $response = file_get_contents($url);

    // Process API response
    // ...

    return $processedData;
}

// Test the script on different servers or environments
$apiUrl = 'https://api.example.com/data';
$data = fetchDataFromAPI($apiUrl);

// Use the $data retrieved from the API
// ...
