Short answer. A civil action is a suit by one party against another to enforce or protect a right, or to prevent or redress a wrong. A criminal action is the State prosecuting a person for an act punishable by law. A special proceeding establishes a status, a right, or a particular fact rather than resolving a dispute.

Civil actions: one party suing another
The Rules of Court define a civil action as one by which a party sues another for the enforcement or protection of a right, or the prevention or redress of a wrong. The marks of a civil action are that private parties face each other and that something is demanded — payment of a debt, delivery of property, performance of a contract, damages for an injury. Civil actions come in two forms: ordinary ones, and special civil actions such as those with their own dedicated rules. Both are governed by the rules for ordinary civil actions, subject to the specific rules prescribed for the special ones.
Criminal actions: the State prosecutes
A criminal action is one by which the State prosecutes a person for an act or omission punishable by law. The difference in the parties is the point: even where a private person was the victim and files the complaint, the case is titled and pursued in the name of the People of the Philippines, because a crime is treated as an offence against the public, not merely against the person harmed. What is at stake is also different — a criminal case can end in imprisonment or a fine payable to the State, while a civil case ends in relief for the winning party.
Special proceedings: no opponent required
A special proceeding is a remedy by which a party seeks to establish a status, a right, or a particular fact. Unlike a civil action, it does not necessarily involve suing anybody. The petitioner asks the court to declare or settle something — that a person has died and the estate should be distributed, that a guardian should be appointed, that an entry in a civil registry should be corrected. There may be oppositors, but the proceeding exists to establish the fact or status, not to redress a wrong committed by a defendant.
Why the classification matters
The label determines which set of rules governs the case from filing to judgment — how it is commenced, what pleadings are allowed, what the court must find, and how the decision is reviewed. Filing the wrong kind of case can cost months: relief that requires a special proceeding cannot simply be tacked onto an ordinary suit, and a claim between private parties cannot be pursued as if it were a prosecution. Before filing anything, identify what you actually want the court to do — enforce a right against someone, punish an offence, or establish a fact — and the correct vehicle follows from that.
