The same things
refers to
things Paul already taught the Philippians in person; or
rejoicing.
Paul is about to warn the Philippians against the doctrine of the Judaizers, who promote circumcision and the Mosaic law. Most likely, Paul had taught the Philippians about the dangers of the Judaizers in the past, either in person or in another letter, and now he says that he will repeat this instruction. It is not troublesome for Paul to do so, and it is safe for the Philippians, for the doctrine of the Judaizers is damaging to the gospel.
Some contend that when Paul refers to the same things,
he has in mind his command to rejoice. These point out that Paul has repeated mentioned rejoicing in the letter to the Philippians (Philippians 2:17–18, Philippians 2:29) and he does so again in Philippians 3:1 when he writes, Rejoice in the Lord.
He then follows up this command by saying it is not troublesome and it is safe for them to write the same things. In other words, it is not troublesome for Paul to command the Philippians to rejoice again.
The problem here is that when Paul refers to the same things, the adjective is in the plural. That suggests that Paul has a body of content in mind, and not the singular command to rejoice. Further, rejoicing is a fairly common Christian sentiment, so it is not clear why Paul would point out that he repeats this command, nor how rejoicing would be a safeguard for the Philippians. On the other hand, it is natural to take Paul’s instructions that follow concerning the Judaizers to be a safeguard.
Thus, when Paul says that he writes the same things again, he likely means that he will again warn the Philippians against the teachings of the Judaizers.
Interpretation 1:
Paul refers to things he already taught the Philippians in person.
Summary:
Paul is about to warn the Philippians against the notion that righteousness depends on obeying the Mosaic law, including circumcision. Before outlining this warning, Paul says that it is not troublesome for him to write the same things to the Philippians, and it is safe for them. In other words, Paul has already warned the Philippians against falling into legalism, for we are justified by faith, and he will repeat these warnings here.
It is critical for Christians to understand the fact that we are saved by grace through faith in Jesus Christ. In other words, we do not earn God’s favour by performing the right actions, because all of our actions are tainted by sin. Rather, God’s favour is a gift of grace because of the work of Christ. It is a safeguard to remind each other of the meaning of grace.

Minor differences:
Our authors agree that Paul refers to past instructions given to the Philippians concerning the Judaizers. The Judaizers mingled Jewish beliefs around upholding the Mosaic law with Christian beliefs. Paul must have warned the Philippians to watch out for the doctrines of the Judaizers in the past and does so again in Philippians 3:2–16.
There is a slight difference between Marvin Vincent and the others. For most of our authors, when Paul refers to his previous instruction to the Philippians concerning the Judaizers, he likely refers to instruction he gave to them in person. We know Paul had ministered to the Philippians in person, and now he likely refers to teachings he had spoken to them face to face.1 For Vincent, on the other hand, Paul refers to other letters he previously wrote to the Philippians, but which are lost to history.2

Interpretation 2:
Paul refers to rejoicing.
Summary:
Paul calls the Philippians to rejoice several times throughout this letter, and now he repeats that command. It is no trouble for Paul to repeat the command to rejoice, but it is safe for the Philippians.

1 Finally, my brothers, rejoice in the Lord. To write the same things to you is no trouble to me and is safe for you.
