Regular Expressions

Well I'm new to regular expressions so I need some help:
I need some regexps that parse the followin lines:

>>> Map: goldrush
Overall stats for: Snyke (1 Round)
Luger    :  20.5    9/44       1      0         0
Damage Given: 4980    Team Damage: 897
Damage Recvd: 4129
Rank: Hauptmann (519 XP)
Heavy Weapons  0 (15/20)          0
Axis   Hyp3r10n         65  20   1 11  76  14 12305  4276 2221   1523
Stats recorded: 00:25:10 (27 Nov 2003)

They are just sample log files from Wolfenstein Enemy Territory If you need it I will post an entire log.
Notice that I need as much information from the above as possible...

Can you be more specific? I don't understand what you want to do with the lines.

If you just want to pull out the numeric data, you could use a regEx along the lines of:

[^0-9]*([0-9]*)


Here's what it means:

* [] designates a set. It will match any characters you list in the set, and you can specify ranges of characters (e.g., 0-9 fo all digits, a-z for all letters)

* ^ A set with a ^ character at the beginning designates a set that while match any character that is NOT inside the brackets (e.g., [^0-9] will match anything that is not a numeric characeter.

* () are used to store a group for future reference. You can store a number of groups in a regular expression, and then refere to them with \1, \2, \3, etc. Here's an example.

$stringToParse = "Damage Given: 4980    Team Damage: 897"
$regEx =  "[^0-9]*([0-9]*)[^0-9]*([0-9]*)"

When you use php's ereg function, you can get an array containing all of the values it found in the stored groups.

if ereg($stringToParse, $regEx, $resultsArray) { // do stuff if it found a match }

$resultsArray is passed by reference into the ereg function, so it isn't a variable you need to do anything with before calling ereg. After you call ereg, you'll get the following results.

$resultsArray = Array(
[0] => "Damage Given: 4980    Team Damage: 897" // the entire string matched
[1] => "4980" // The first stored group
[2] => "897" // The second stored group

Hope this helps!
