PHP Looping an array and running a function on a array item - php

Question

I seem to get this issue a few times and figure it out then the next time I come across it I can't figure it out.
So I have a SQL statement which returns to a $result variable as usual...
$result = $stmt->fetchAll( PDO::FETCH_ASSOC );
I will show you a slimmed down return below
Array
(
[eid] => 1
[eTitle] => premier league
[eDesc] =>
[cid] => 1
[deleted] => 0
[eStartTime] => 15:00
[eHome] => 1
[eAway] => 2
[eKickoff] => 15:00:00
[eDate] => 2016-08-20
)
Array
(
[eid] => 2
[eTitle] => fa cup
[eDesc] =>
[cid] => 1
[deleted] => 0
[eStartTime] => 15:00
[eHome] => 1
[eAway] => 2
[eKickoff] => 15:00:00
[eDate] => 2016-08-27
)
Now what i want to do is loop through the $result and on each key eHome and eAway run a function below is the pseudo code for what I am trying to do.
loop ( $reult )
$row[eHome][eHomeData] = $this->getTeam( $row['eHome'] )
$row[eHome][eAwayData] = $this->getTeam( $row['eAway'] )
So basically I want to rebuild the array with the home or away team data which uses the id given in eHome and eAway.
Should I do it like this or should I be using JOINS in MySQL?
Sorry if I have worded this badly I having been struggling for a few hours with this and gave up.
Thanks in advance guys.

This is what I have used in the end guys sorry for the poorly worded question. Is there a better way to do this, here is the code and then the print_r() dump for you to see where I was going with this.
$stmt = $this->conn->prepare('
SELECT * from events WHERE cid = :cid
');
$stmt->bindParam( ':cid', $categoryid, PDO::PARAM_INT );
if( $stmt->execute() )
{
$result = $stmt->fetchAll( PDO::FETCH_ASSOC );
$resultCount = count($result);
for( $i = 0; $i < $resultCount; $i++ ) {
$result[$i]['homeTeamData'] = $this->getTeam( $result[$i]['eHome'] );
$result[$i]['awayTeamData'] = $this->getTeam( $result[$i]['eAway'] );
}
}
Below is the print_r() which adds an extra awayTeamData and homeTeamData with the data collected in the loop added above
