What steps can be taken to troubleshoot and debug the db_Execute function in the given PHP code?

The db_Execute function may not be working as expected due to errors in the SQL query or database connection. To troubleshoot and debug the function, we can add error handling to catch any exceptions thrown during query execution and print out the error message for further investigation. 

function db_Execute($query) {
    global $db_conn;
    
    try {
        $stmt = $db_conn->prepare($query);
        $stmt->execute();
        return true;
    } catch (PDOException $e) {
        echo "Error executing query: " . $e->getMessage();
        return false;
    }
}
