How to echo second column with only the primary key - SQL/PHP - php

Question

I'm trying to create a fixture list for a football competition currently, and i have been stuck with trying to display something like "team1name V team2name".The tables that i am trying to pull the data from are:
Team
teamID
teamname
Fixtures
hometeam
awayteam
The sql query I have written up is:
$sql = "SELECT homeTeam, awayTeam, roundID, teamID, teamName, logo, groundName, abbreviatedName, matchDate, matchTime, venue
FROM fixtures
INNER JOIN team ON fixtures.homeTeam = team.teamID
INNER JOIN ground ON ground.groundID = team.groundID";
$results = mysqli_query($conn, $sql)
or die ('Problem with query' . mysqli_error());
and the PHP code which i have been using to display this data is:
<?php
while ($row = mysqli_fetch_array($results))
{
?>
<tr>
<td><?php echo $row ["teamName"]?></td>
<td> V </td>
<td><?php echo $row ["teamName"]></td>
</tr>
<?php
}
mysqli_close($conn);
?>
I understand i am calling teamname twice and hence why i am getting the same name displayed, but i am unsure as to how to get my code to differentiate the two IDs and names. Any help would be greatly appreciated

This is just a SQL problem. You need to join team twice, once for home team and once for away team.
SELECT homeTeamID, awayTeamID, homeTeam.teamID homeTeamID,
awayTeam.teamID awayTeamID, homeTeam.teamName homeTeamName,
awayTeam.teamName awayTeamName
FROM fixtures
INNER JOIN team homeTeam ON fixtures.homeTeam = homeTeam.teamID
INNER JOIN team awayTeam ON fixtures.awayTeam = awayTeam.teamID
INNER JOIN ground ON ground.groundID = team.groundID
By naming the selects, you can use the separately in your PHP code.
<?php echo $row['homeTeamName']; ?> v <?php echo $row['awayTeamName']; ?>
