What are common errors encountered when integrating PayPal into a website using PHP?

One common error when integrating PayPal into a website using PHP is not properly setting up the PayPal SDK or API credentials. Make sure to include the correct credentials in your PHP code to authenticate with PayPal's servers. Another common error is not handling errors or exceptions properly, leading to issues with the payment process. Implement error handling to catch and handle any errors that may occur during the PayPal integration process. 

// Set up PayPal SDK and API credentials
require 'vendor/autoload.php';
$clientId = 'YOUR_CLIENT_ID';
$clientSecret = 'YOUR_CLIENT_SECRET';
$environment = new \PayPal\Rest\ApiContext(
    new \PayPal\Auth\OAuthTokenCredential($clientId, $clientSecret)
);

// Handle errors or exceptions
try {
    // Your PayPal integration code here
} catch (Exception $e) {
    echo 'Error: ' . $e->getMessage();
}
