What are common challenges faced when troubleshooting PHP scripts purchased from third-party vendors?

Common challenges when troubleshooting PHP scripts purchased from third-party vendors include compatibility issues with your server environment, lack of documentation, and limited support from the vendor. To address these challenges, it is important to thoroughly review the script's requirements and ensure they align with your server setup, search for online resources or forums for troubleshooting tips, and consider reaching out to the vendor for assistance. 

// Example of checking PHP version compatibility
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    echo 'This script requires PHP version 7.0.0 or higher.';
    exit;
}
