One of my friend told me to break my legs before entering the examination hall…I was confused with her words! How am I supposed to sit for the exam if i broke my legs? Or maybe is it kind of idioms/phrases?

The usage of the phrase "break a leg" originates from within the theatrical profession. It was considered that to wish an actor "good luck" for a performance was to "jinx" them and have the opposite effect. As a result it was wished they would "break a leg" and thus cause "good luck".
This is referenced in the movie the Producers where you can hear it used in this song.
