What are some common strategies for error handling and debugging when working with HTTP requests and processing responses in PHP scripts, particularly when dealing with complex web service interactions like the one described in the thread?

Issue: When working with HTTP requests and processing responses in PHP scripts, it's important to handle errors effectively to ensure smooth operation of web service interactions. Common strategies include using try-catch blocks to catch exceptions, checking for HTTP status codes to identify errors, and logging detailed error messages for debugging purposes. PHP Code Snippet: 

try {
    $response = file_get_contents('http://api.example.com/data');
    
    if ($response === false) {
        throw new Exception('Failed to fetch data from the API');
    }
    
    $httpStatus = explode(' ', $http_response_header[0])[1];
    
    if ($httpStatus !== '200') {
        throw new Exception('HTTP request failed with status code: ' . $httpStatus);
    }
    
    // Process the response data here
    
} catch (Exception $e) {
    error_log('Error: ' . $e->getMessage());
    // Handle the error gracefully, e.g. display a user-friendly message
}
