如果存在公共值，则将数组内的元素组合在一起
问题描述：
I have this snippet of code:
foreach($data['matches'] as $record){
$matchday = $record['matchday'];
echo '<h4>Round'. $matchday .'</h4><br>'.$record['homeTeam']['name'].' - '.$record['awayTeam']['name'].'<br>';
}
It will loop over a multidimensional array to show all the calendar matches of a competition, matches is the key who contain the array I'm using. I need to extract only once the matchday for every season round to display all the matches of every round under an header <h4> like something round 1, round 2 ecc. Every round have ten matches and if I use the loop to display also the information about the current round, it will duplicate this information, but I need to group them if they are under the same round. Is it possible to achieve this?
The idea is to obtain something like:
Round 1
team 1 - team 2
team 3 - team 4
team 5 - team 6
Round 2
team 1 - team 2
team 3 - team 4
team 5 - team 6
ecc..
now the data are displayed like this:
Round 1
team 1 - team 2
Round 1
team 3 - team 4
Round 1
team 5 - team 6
Round 2
team 1 - team 2
Round 2
team 3 - team 4
Round 2
team 5 - team 6
ecc..
EDIT Here is the array who I'm working on (I will take only two matches of the first round):

答
Simple, Take one extra variable and check that the current round and previous round value are same or not.
Something like below.
$roundName = "";
foreach($data['matches'] as $record){
$matchday = $record['matchday'];
if($roundName != $matchday){
echo '<h4>Round'. $matchday .'</h4><br>';
}
echo $record['homeTeam']['name'].' - '.$record['awayTeam']['name'].'<br>';
$roundName = $record['matchday'];
}
Other solution is,
Make one Multidimentional array with key as round name.
Something like,
$array['round1'][0] = 'team 1 - team 2';
$array['round1'][1] = 'team 3 - team 5';
$array['round2'][0] = 'team 1 - team 2';
$array['round2'][1] = 'team 3 - team 5';
................
................
................
................
$array['roundn'][n] = 'team 3 - team 5';
