Is the saying 'all intensive purposes' or 'all intense purposes'?

Answer:
Neither of the phrases in the question is correct.

The correct wording, in American English, is "for all intents and purposes." In British English, however, the wording of the selfsame idiom is "to all intents and purposes."
