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) Last problem: https://www.regex101.com/r/wP8cW1/1

You may use regex (?P<ID>\d+)\s+(?P<IP>\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}:\d+)\s(?P<PINGR>\d+)\s(?P<IDENTIFIERNUMBER>ID\d+)(\(OK\))?(?P<USERNAME>(\s[A-z]\w+)+) MATCH 1 ID [0-1] `0` IP [2-16] `127.0.0.1:1234` PINGR [17-18] `0` IDENTIFIERNUMBER [19-30] `ID123456789` USERNAME [31-37] `Moritz` MATCH 2 ID [39-40] `1` IP [41-55] `127.0.0.1:1234` PINGR [56-58] `46` IDENTIFIERNUMBER [59-70] `ID123456789` USERNAME [71-83] `August Jones` MATCH 3 ID [85-86] `2` IP [87-101] `127.0.0.1:1234` PINGR [102-104] `46` IDENTIFIERNUMBER [105-116] `ID123456789` USERNAME [117-123] `Miller` Demo and explanation

Do you alredy try explode the string by new lines \n ?? test this code. $str = '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'; $lines = array_filter(explode("\n", $str)); foreach ($lines as $value) { $t[] = preg_split("/\s+/", trim($value)); } Now in the var $t you have a usefull data.
