What is the error message "Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource" indicating in the PHP code provided?

The error message "Warning: mysql_fetch_object(): supplied argument is not a valid MySQL result resource" indicates that the result set returned by the MySQL query is not valid or empty. This can happen due to various reasons such as an error in the query, connection issue, or no rows matching the query criteria. To solve this issue, you need to check if the query execution was successful before fetching the results. 

$result = mysql_query("SELECT * FROM table_name");

if($result && mysql_num_rows($result) > 0) {
    while($row = mysql_fetch_object($result)) {
        // Process each row here
    }
} else {
    echo "No results found or an error occurred.";
}
