Two or three men named Philip appeared in the Bible, including 1 of the disciples of Jesus Christ.
Acts spoke of a man named Philip who was chosen to minister to the Greek Jews and the Gospels showed Herodius' brother whose wife and daughter had a part in the death of John the Baptist.
Three of the Gospel books and the book of Acts had the disciple Philip in them.
Matthew 10:2-4 and Mark 3:16-19 named 12 disciples that followed Jesus.
Luke 6:12-16 also named Philip as a disciple in verse 14:
12. One of those days Jesus went out to a mountainside to pray, and spent the night praying to God.
13. When morning came, he called his disciples to him and chose twelve of them, whom he also designated apostles:
14. Simon (whom he named Peter), his brother Andrew, James, John, Philip, Bartholomew,
15. Matthew, Thomas, James son of Alphaeus, Simon who was called the Zealot,
16. Judas son of James, and Judas Iscariot, who became a traitor.
Philip appeared several times in the book of John. John 1:43-51 stated that Philip and Nathanael (also known as Bartholomew) were the third and fourth disciples of Jesus. As Jesus prepared to feed (at least) 5,000 people with just 5 loaves of bread and 2 small fish, Philip spoke to Jesus in John 6:5-7, then later in John 14:8-9 he was part of a conversation with Jesus about God. John 1:44 stated: "Philip, like Andrew and Peter, was from the town of Bethsaida.".
Acts 1:12-14 (after Jesus' ascension to Heaven when he rose from the dead after 3 days):
12. Then they returned to Jerusalem from the hill called the Mount of Olives, a Sabbath day's walk from the city.
13. When they arrived, they went upstairs to the room where they were staying. Those present were Peter, John, James and Andrew; Philip and Thomas, Bartholomew and Matthew; James son of Alphaeus and Simon the Zealot,
and Judas son of James.
14. They all joined together constantly in prayer, along with the women and Mary the mother of Jesus, and with his brothers.
It's unclear as to whether the disciple Philip became 1 of the 7 men chosen in Acts 6:5 to ensure the Greek widows were taken care of or if this was another man altogether. Since the Twelve (disciples) were stated in verse 2, it's quite possible there was another man named Philip that was quite favorably portrayed in Acts 8.
Acts 6:5:
1. In those days when the number of disciples was increasing, the Grecian Jews among them complained against the Hebraic Jews because their widows were being overlooked in the daily distribution of food.
2. So the Twelve gathered all the disciples together and said, "It would not be right for us to neglect the ministry of the word of God in order to wait on tables.
3. Brothers, choose seven men from among you who are known to be full of the Spirit and wisdom. We will turn this responsibility over to them
4. and will give our attention to prayer and the ministry of the word."
5. This proposal pleased the whole group. They chose Stephen, a man full of faith and of the Holy Spirit; also Philip, Procorus, Nicanor, Timon, Parmenas, and Nicolas from Antioch, a convert to Judaism.
6. They presented these men to the apostles, who prayed and laid their hands on them.
7. So the word of God spread. The number of disciples in Jerusalem increased rapidly, and a large number of priests became obedient to the faith.
While I'm not sure if this referred to the disciple Philip, I can be sure it pointed to 1 of the 7 men from Acts 6 because he was accompanied by Stephen who was stoned as a martyr.
After he traveled through Samaria ealier in Acts chapter 8 leading people to Christ and baptizing them, Philip baptized an Ethiopian eunuch - Acts 8:26-39:
26. Now an angel of the Lord said to Philip, "Go south to the road--the desert road--that goes down from Jerusalem to Gaza."
27. So he started out, and on his way he met an Ethiopian eunuch, an important official in charge of all the treasury of Candace, queen of the Ethiopians. This man had gone to Jerusalem to worship,
28. and on his way home was sitting in his chariot reading the book of Isaiah the prophet.
29. The Spirit told Philip, "Go to that chariot and stay near it."
30. Then Philip ran up to the chariot and heard the man reading Isaiah the prophet. "Do you understand what you are reading?" Philip asked.
31. "How can I," he said, "unless someone explains it to me?" So he invited Philip to come up and sit with him.
32. The eunuch was reading this passage of Scripture: "He was led like a sheep to the slaughter, and as a lamb before the shearer is silent, so he did not open his mouth.
33. In his humiliation he was deprived of justice. Who can speak of his descendants? For his life was taken from the earth."
34. The eunuch asked Philip, "Tell me, please, who is the prophet talking about, himself or someone else?"
35. Then Philip began with that very passage of Scripture and told him the good news about Jesus.
36. As they traveled along the road, they came to some water and the eunuch said, "Look, here is water. Why shouldn't I be baptized?"
37. And he gave orders to stop the chariot. Then both Philip and the eunuch went down into the water and Philip baptized him.
38. When they came up out of the water, the Spirit of the Lord suddenly took Philip away, and the eunuch did not see him again, but went on his way rejoicing.
39. Philip, however, appeared at Azotus and traveled about, preaching the gospel in all the towns until he reached Caesarea.
Lastly, the brother of Herodias was also named Philip who first showed in Matthew 14:3 and also in 2 other Gospels.
Matthew 14:1-12:
1. At that time Herod the tetrarch heard the reports about Jesus,
2. and he said to his attendants, "This is John the Baptist; he has risen from the dead! That is why miraculous powers are at work in him."
3. Now Herod had arrested John and bound him and put him in prison because of Herodias, his brother Philip's wife,
4. for John had been saying to him: "It is not lawful for you to have her."
5. Herod wanted to kill John, but he was afraid of the people, because they considered him a prophet.
6. On Herod's birthday the daughter of Herodias danced for them and pleased Herod so much
7. that he promised with an oath to give her whatever she asked.
8. Prompted by her mother, she said, "Give me here on a platter the head of John the Baptist."
9. The king was distressed, but because of his oaths and his dinner guests, he ordered that her request be granted
10. and had John beheaded in the prison.
11. His head was brought in on a platter and given to the girl, who carried it to her mother.
12. John's disciples came and took his body and buried it. Then they went and told Jesus.
Mark 6:17:
17. For Herod himself had given orders to have John arrested, and he had him bound and put in prison. He did this because of Herodias, his brother Philip's wife, whom he had married.
Luke 3:1-5:
1. In the fifteenth year of the reign of Tiberius Caesar--when Pontius Pilate was governor of Judea, Herod tetrarch of Galilee, his brother Philip tetrarch of Iturea and Traconitis, and Lysanias tetrarch of Abilene--
2. during the high priesthood of Annas and Caiaphas, the word of God came to John son of Zechariah in the desert.
3. He went into all the country around the Jordan, preaching a baptism of repentance for the forgiveness of sins.
4. As is written in the book of the words of Isaiah the prophet: "A voice of one calling in the desert, `Prepare the way for the Lord, make straight paths for him.
5. Every valley shall be filled in, every mountain and hill made low. The crooked roads shall become straight, the rough ways smooth.
6. And all mankind will see God's salvation.'"
