Question

I have two MySQL tables which look like these

Teams

id  name    abbr_name   badge   slogan  captain
1   TEAM1   TM1     NULL    NULL    NULL
2   TEAM2   TM2     NULL    NULL    NULL
3   TAEM3   TM3     NULL    NULL    NULL
4   TEAM4   TM4     NULL    NULL    NULL
5   TEAM5   TM5     NULL    NULL    NULL
....

Match Entries

id  season  match_day   host    guest   time    host_score  guest_score  forfait mvp
1   1   1   3   4   NULL    10  2   NULL    43
2   1   1   5   6   NULL    2   2   NULL    16
3   1   1   9   10  NULL    6   3   NULL    49
4   1   1   2   1   NULL    5   5   NULL    29
5   1   1   7   8   NULL    4   2   NULL    52
6   1   2   1   4   NULL    7   3   NULL    75
....

What i would like to do is to make a query which can give me all the rows with values

Team_Id, Team_name, Team_N_Match_Played, Team_N_Match_Won, Team_N_Match_Lost

Is that possible without manipulating all the data with PHP and using MySQL queries directly instead?
I have no idea how I can fo that in MySQL.

MatchEntries = dc_match
Teams = dc_teams

SELECT
    team_id,
    name,
    SUM(P) AS played,
    SUM(W) AS won,
    SUM(D) AS draw,
    SUM(L) AS lost,
    SUM(PTS) AS points
FROM(
    SELECT
        host team_id,
        CASE
            WHEN host_score IS NULL THEN 0
            ELSE 1
        END P,
        IF (host_score > guest_score,1,0) W,
        IF (host_score = guest_score,1,0) D,
        IF (host_score < guest_score,1,0) L,
        CASE 
            WHEN host_score > guest_score THEN 3
            WHEN host_score = guest_score THEN 1 
            ELSE 0
        END PTS
    FROM dc_match

    UNION ALL

    SELECT
        guest team_id,
        CASE
            WHEN guest_score IS NULL THEN 0
            ELSE 1
        END P,
        IF (guest_score > host_score,1,0) W,
        IF (guest_score = host_score,1,0) D,
        IF (guest_score < host_score,1,0) L,
        CASE 
            WHEN guest_score > host_score THEN 3
            WHEN guest_score = host_score THEN 1 
            ELSE 0
        END PTS
    FROM dc_match
    ) AS RNK
LEFT JOIN dc_team t
    ON RNK.team_id = t.id
GROUP by team_id
ORDER BY points DESC
