Are There Cheat Codes for LittleBigPlanet on PS3? No – Use Level Editor

No official cheat codes exist for LittleBigPlanet on PS3. Instead, the game's powerful level editor lets you create custom experiences that effectively function as "cheats":

• Unlimited health via custom power-ups
• Infinite jumps with modified springs
• Adjusted speed for Sackboy
• Invisible walls or removed barriers

These only work in your own created levels. For the main game, practice, power-ups, and community-created levels are the intended ways to overcome challenges.
