"Love & Hip Hop: Hollywood" star Milan Christopher took his war with his ex-bf to the next level -- going to court to get protection after Miles Brock allegedly attacked him last weekend.
An L.A. judge signed off on Milan's request for a restraining order on Monday ... meaning Brock has to stay at least 100 yards away from Milan. In the docs, Christopher accuses Brock of punching him in the face, resulting in a "swollen face black eye."
TMZ broke the story ... Brock was arrested Saturday night in NYC, a day after the exes ended up at the same Halloween party where the punch allegedly went down.
We got Milan on his way out of court, and he insists ... there won't be any reconciliation.
