// Assume that $userId is the ID of the user. $messages = getUsersMessages($userId); // Loop through all the messages. foreach ($messages as $message) { echo $message->content; }In this example, the getUsersMessages() function is called with the ID of the user whose messages we want to retrieve. Then we loop through all the messages using a foreach loop, and display the content of each message. The package library that contains the getUsersMessages() function is likely to be a messaging library or a user management library, such as the PHP Messaging Library or the PHP User Management Library.
