What are some alternative approaches to finalizing a purchase in PHP that could potentially prevent the script from hanging or causing errors?

When finalizing a purchase in PHP, one common issue that can occur is the script hanging or causing errors due to slow processing or server timeouts. To prevent this, one alternative approach is to use asynchronous processing or background tasks to handle the purchase confirmation and any related tasks without blocking the main script execution. 

// Example of using asynchronous processing with cURL to finalize a purchase

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

// Set cURL options
curl_setopt($ch, CURLOPT_URL, 'https://example.com/finalize_purchase.php');
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query(['purchase_id' => $purchase_id]));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

// Execute cURL request asynchronously
curl_exec($ch);

// Close cURL session
curl_close($ch);

// Continue with other tasks or redirect user
