What are common errors when using mysql_fetch_object in PHP?

Common errors when using mysql_fetch_object in PHP include not checking if the query returned any results before trying to fetch objects, not specifying the correct database connection, and not handling errors properly. To solve these issues, always check if the query returned results, ensure the database connection is established, and handle any potential errors that may occur during the fetching process. 

// Check if the query returned any results before fetching objects
$result = mysqli_query($connection, $query);
if ($result && mysqli_num_rows($result) > 0) {
    while ($row = mysqli_fetch_object($result)) {
        // Process the fetched object here
    }
} else {
    echo "No results found.";
}

// Make sure the database connection is established
$connection = mysqli_connect("localhost", "username", "password", "database_name");
if (!$connection) {
    die("Connection failed: " . mysqli_connect_error());
}

// Handle errors properly
if (!$result) {
    die("Error: " . mysqli_error($connection));
}
