A friend told some lies about me to the whole school.

That is a very damaging situation. It is not uncommon for friends to get into conflict and argue, but this is a major issue if your friend is knowingly spreading false information about you to others. Try to talk it through with your friend and explain how hurt you are by this. If they refuse to acknowledge their wrongdoing, consider taking more formal steps, such as speaking to a teacher or parent about the situation.
