What considerations should be made when integrating third-party libraries or objects into PHP scripts, especially when they rely on specific resources like the $DB object in this case?

When integrating third-party libraries or objects into PHP scripts that rely on specific resources like the $DB object, it is important to ensure that the required resources are available and properly initialized before using them. This can be achieved by checking if the $DB object exists and is an instance of the expected class before using it in the third-party library. 

// Check if $DB object exists and is an instance of the expected class
if (isset($DB) && $DB instanceof Database) {
    // Use the $DB object in the third-party library
    $thirdPartyLibrary->setDatabase($DB);
} else {
    // Handle the case where $DB object is not available or not the expected class
    echo "Error: Database object not available or not the expected class.";
}
