PHP: filter specific pattern out of string

My raw output of socket_recvfrom is:

ID IP PING IDENTIFIERNUMBER USERNAME

---

0 127.0.0.1:1234 0 ID123456789 Moritz

1 127.0.0.1:1234 46 ID123456789 August Jones

2 127.0.0.1:1234 46 ID123456789 Miller

---

It is a single string that contains all of this informations in once and just contains whitespaces between the informations. All keys can be longer or shorter.

My problem:

When I preg_split("/\s+/") it, then I get a good array with useable data, but when the username contains spaces it creates a second index for this. Not good, all data that comes after this just get destroyed.

I sort the array like this: ID, USERNAME, PING, IDENTIFIERNUMBER, IP

Example by the sorting output with username with one space in it:

---

ID: 0, USERNAME: Moritz, PING: 0, IDENTIFIERNUMBER: ID123456789, IP: 127.0.0.1:1234

ID: 1, USERNAME: August, PING: Jones, IDENTIFIERNUMBER: 46, IP: ID123456789

ID: 127.0.0.1:1234, USERNAME: 2, PING: Miller, IDENTIFIERNUMBER: 46, IP: ID123456789

How do I get the information correctly out of the string?

Just forgot to say:

The string begins with: --------------------------------- in a not countable order. So it can be like 10 characters or 12. The string ends with:

 (8 users in total)

The regex methode looks good. I only need to filter out the other characters.

--------------------------------- 0 127.0.0.1:1234 0 ID123456789(OK) Moritz 1 127.0.0.1:1234 46 ID123456789(OK) August Jones 2 127.0.0.1:1234 46 ID123456789(OK) Miller (7 users in total)
