What steps can be taken to troubleshoot a PHP script that breaks after calling curl_init()?

The issue of a PHP script breaking after calling curl_init() may be due to a variety of reasons such as missing cURL extension, incorrect cURL configuration, or server-related issues. To troubleshoot this problem, ensure that the cURL extension is enabled in your PHP configuration, check for any errors returned by curl_init(), and verify that the necessary cURL options are set correctly. 

// Check if cURL extension is enabled
if (!function_exists('curl_init')) {
    die('cURL extension is not enabled');
}

// Initialize cURL session
$ch = curl_init();

// Check for any errors during cURL initialization
if (!$ch) {
    die('Failed to initialize cURL');
}

// Set cURL options and perform necessary operations

// Close cURL session
curl_close($ch);
