How can PHP developers handle errors and troubleshoot issues when including external content in their scripts?

When including external content in PHP scripts, developers should handle errors by checking for the existence of the file or URL before including it. This can prevent issues such as fatal errors or security vulnerabilities. Additionally, developers can troubleshoot problems by enabling error reporting and logging to identify the source of the issue. 

// Check if the external file exists before including it
$external_file = 'https://example.com/external.php';
if (file_exists($external_file)) {
    include $external_file;
} else {
    echo 'External file not found';
}

// Enable error reporting and logging for troubleshooting
error_reporting(E_ALL);
ini_set('display_errors', 1);
ini_set('log_errors', 1);
ini_set('error_log', '/path/to/error.log');
