包括…在内【bāokuò … zàinèi】

包括…在内 wraps a noun and counts it in: "including X, X included". It's neutral to written, and common in notices and prices.

The phrase can open the sentence or follow what it adds to. After a group, it's often followed by 都.

在内 can be dropped, leaving plain 包括, "include". Keeping it stresses that the item counts too.

连…在内

连 can take the place of 包括, usually before a person.

The noun goes inside

Both halves wrap the noun; 在内 doesn't come first, and the noun doesn't come after it.

• × 包括在内我，一共五个人 → 包括我在内，一共五个人

除了…以外 can mean "except" as well as "besides". 包括…在内 never leaves anything out.
