Programming :: MySQL And PHP - Table Column With Multiple Values?

I am writing a script to mine data from my game server logs which are going to mysql. My first question is syslog-ng is sticking $msg into one colum it self, $msg tends to be a long string here are a few examples:

cn name team frag death flags role host.
0 Maik CLA 2 0 0 normal *.70.233.118.
1 lizardncd RVSF -1 3 0 normal
[*.22.247.40] lizardncd fragged Maik.

And they are not always in the same format, How could I parse this data to do something useful, like creating a user stats page with frag counts and flag counts. Should I create a script that runs in a cronjob that parses this data to a new table maybe once a day. Even then the $msg string value is random and I am thinking in terms of awk.

Second. I would like to keep track of what ip's are using what nicknames. Kinda in the sense of and ip associated to a array of names that have been used on that ip address so I can keep track of users. How would this work logically with a mysql db, could a column allow multiple values, then loadable into an array, which then can add, remove, and store to mysql.
