$accountEntity = new CRMEntity('Accounts'); $accountEntity->retrieve($accountId); $contactModule = new CRMModule('Contacts'); $contacts = $contactModule->getEntries(array('account_id' => $accountId)); foreach ($contacts as $contact) { $accountEntity->save_related_module('Contacts', $contact); }In this example, we first retrieve the account entity using the CRMEntity object. We then use a CRMModule object to retrieve all associated contacts for the account. Finally, we iterate over each contact and call the save_related_module method on the account entity to save the contact rela tionship. The specific package or library that provides the save_related_module method will depend on the particular CRM system being used. Popular CRM platforms like Salesforce and SugarCRM have their own PHP libraries that provide similar functionality.
