Charm Person. 1st level. Sets target’s attitude to Friendly. Which means what exactly—see the Diplomancer arguments, threads.
Duration 1 hour/ level--way longer than a combat encounter, but not long enough for permanent influence games. A lot of ambiguity in what the spell can do, which is why in most of the games I'm in it gets pushed to the side.

Command. 1st level. One target, one very simple (one word) action. Does what it says on the tin.

Hold Person. 2nd level. Paralyzes subject. (Does not require further action by caster).
Tasha's Hideous Laughter. 2nd level. Subject is prone, takes no actions for 1 round/CL.

Suggestion. 3rd level. Causes target to do something that seems like a reasonable thing to do. 1 hour/level.

Lesser Geas. 4th level. Will save or carry out action until complete or for 1 day/level.
Glibness. 3nd level Bard. +30 to Bluff checks for 10 minutes/level.

Dominate Person. 5th level. Duration 1 day/level. Control the actions of the subject. Caster can use subject as long-range limited sensing organ. "Obviously self-destructive orders are not carried out."
