Query multiple tables - display Team Name based on Team ID

My tables structures are

`TblTeam` (`TeamID`, `TeamName`) VALUES
(1,'India'),
(2,'Pakistan'),
(3,'Brazil')
(4,'Poland');

`TblMatch` (`MatchID`, `MatchDate`, `MatchStart`, `MatchEnd`, `Team1ID`, `Team2ID`) VALUES
(1, '19-11-2014', '12:00:00', '13:00:00', 1, 2),
(2, '19-11-2014', '13:10:00', '14:10:00', 4, 3),
(3, '19-11-2014', '14:20:00', '15:20:00', 1, 3),
(4, '19-11-2014', '15:30:00', '16:30:00', 4, 2),
(5, '20-11-2014', '10:00:00', '11:00:00', 1, 4),
(6, '20-11-2014', '11:10:00', '12:10:00', 3, 4);

INSERT INTO TblScore (ScoreID, TeamID, MatchID, Score) VALUES (1, 1, 1, 5), (2, 2, 1, 6), (3, 4, 2, 15), (4, 3, 2, 26);

I want to display Team Name of (Team1ID, Team2ID) say on 19-11-2014 there are 4 matches so 

in php the output should be

Time                   : Between :
12:00:00 - 13:00:00      India v/s Pakistan
13:10:00 - 14:10:00      Poland v/s Brazil


SELECT m.MatchID, m.MatchDate, m.MatchStart, m.MatchEnd, m.Team1ID, m.Team2ID, 
t.TeamID, t.TeamName 
FROM TblMatch m, TblTeam t WHERE m.MatchDate ='$todayis' ORDER BY m.MatchDate

PHP

while($row=mysqli_fetch_array($res)){
    $mid= $row['MatchID'];
    $mdd = $row['MatchDate'];
    $t1 = $row['Team1ID'];
    $t2 = $row['Team2ID'];
    $t1n = $row['TeamName']; 


    echo $t1n . " v/s  . " $t1n ;



 }

Score query does not work 

 $query="SELECT 
 m.MatchID, 
 m.MatchDate, 
 m.Team1ID, 
 m.Team2ID, 
 s.TeamID,
 s.MatchID,
 T1.TeamName as TeamName1, 
 T2.TeamName as TeamName2,
 T1S.Score as Team1Score,
 T2S.Score as Team2Score
 FROM TblMatch m  JOIN TblTeam T1  ON m.Team1ID = T1.TeamID JOIN TblTeam T2  ON m.Team2ID =      T2.TeamID  JOIN TblScore s ON m.Team1ID = T1S.TeamID JOIN TblScore s ON m.Team1ID = T1S.TeamID  JOIN   TblScore s ON m.Team2ID = T2S.TeamID WHERE s.MatchID=$mid
 ";

Query:

SELECT  
    m.MatchStart, 
    m.MatchEnd, 
    m.Team1ID, 
    m.Team2ID, 
    T1.TeamName as Teamname1, 
    T2.TeamName as Teamname2
FROM TblMatch m, TblTeam T1, TblTeam T2
 where  m.TEAM1ID = T1.TeamID
and
        m.TEAM2ID = T2.TeamID

php code:

while($row=mysqli_fetch_array($res))
{
$mst= $row['MatchStart'];

$met = $row['MatchEnd'];
$t1n = $row['TeamName1']; 
$t2n = $row['TeamName2']; 

echo 'Time: \t\t between:\r\n';
echo "$mst" . " - " . " $met \t\t" ;
echo "$t1n vs $t2n \r\n";
}

You can join your Match table result twice with your team table so you extract the information of the match and the name of each team. After that you only need concatenate the data you fetch from database in PHP.

SELECT 
    m.MatchID, 
    m.MatchDate, 
    m.MatchStart, 
    m.MatchEnd, 
    m.Team1ID, 
    m.Team2ID, 
    T1.Teamname as Teamname1, 
    T2.TeamName as Teamname2
FROM TblMatch M
JOIN TblTeam T1
    ON M.TEAM1ID = T1.TeamID
JOIN TblTeam T2
    ON M.TEAM2ID = T2.TeamID

PHP Code:

while($row=mysqli_fetch_array($res)){
    $mid= $row['MatchID'];
    $mdd = $row['MatchDate'];
    $t1 = $row['Team1ID'];
    $t2 = $row['Team2ID'];
    $t1n = $row['TeamName1']; 
    $t2n = $row['TeamName2']; 

    echo $t1n . " v/s  . " $t2n ;
}
