PHP JSON parsing formatting

Question

I am parsing JSOn using PHP. Right now my json is working fine i just want to format my output. I have created a rootobj array where i am inserting few properties then inside that rootobj there is another array but i want inner array properties to be in the root element , This is my code

 $rootObj = array(
 MainEvent' => $event_value['MainEvent'],
 'OutcomeDateTime' => $formatteddate->format('Y-m-d H:i:s'),
 'OutcomeDateTimeUTC' => gmdate('Y-m-d H:i:s', strtotime($event_value['OutcomeDateTime']))
 );
 //inner array
 foreach($event_value['Competitors']['Competitors'] as $compKey => $compVal) {
 $teamName = array_key_exists('Team',$compVal) ? $compVal['Team'] : $compVal['Name'];
 $win = $compVal['Win'];
 //Creating Competitor Array
 $CompetitorArray[] = array(
 "Team" => $teamName,
 "Win" => $win,
 );
 }
 $rootObj ['Competitors'] = $CompetitorArray;

This is a sample of my output

 ...
 "MainEvent": "West Perth v Swan Districts",
 "OutcomeDateTime": "2014-07-05 16:05:00",
 "OutcomeDateTimeUTC": "2014-07-05 06:05:00",
 "Competitors": [
 {
 "Team": "West Perth",
 "Win": "1.57"
 },
 {
 "Team": "Swan Districts",
 "Win": "2.35"
 }
 ]
 },
 {
 "MainEvent": "East Fremantle v Perth",
 "OutcomeDateTime": "2014-07-05 16:05:00",
 "OutcomeDateTimeUTC": "2014-07-05 06:05:00",
 "Competitors": [
 {
 "Team": "East Fremantle",
 "Win": "1.22"
 },
 {
 "Team": "Perth",
 "Win": "4.15"
 }
 ]
 },
 {
 "MainEvent": "East Perth v Peel Thunder",
 "OutcomeDateTime": "2014-07-05 16:05:00",
 "OutcomeDateTimeUTC": "2014-07-05 06:05:00",
 "Competitors": [
 {
 "Team": "East Perth",
 "Win": "1.12"
 },
 {
 "Team": "Peel Thunder",
 "Win": "6.00"
 }
 ]
 }
 ],
 .....

Bur i want my output to be like this

 ...
 "MainEvent": "West Perth v Swan Districts",
 "OutcomeDateTime": "2014-07-05 16:05:00",
 "OutcomeDateTimeUTC": "2014-07-05 06:05:00",

Answer 1

 // outside of scope
 $countTeam=0;
 ...
 foreach($event_value['Competitors']['Competitors'] as $compKey => $compVal) {
 $countTeam++;
 $teamName = array_key_exists('Team',$compVal) ? $compVal['Team'] : $compVal['Name'];
 $win = $compVal['Win'];
 //Insert to root object
 $rootObj["Team".$countTeam] = $teamName;
 $rootObj["Win".$countTeam] = $win;
}
