Add key and variable to multidimensional Array based on conditions - php

Question

I wonder if it's possible to add a key and value to an array, based on certain conditions.
This piece of script makes an api-call to retrieve sportresults from multiple teams based on a teamID number.
$length = $numberofTeams
for ($i = 0; $i < $length; $i++) {
$teamID = $objTeamID[$i]['Teamid'];
$teamResults = 'http://api.com/teamresults/' . $Teamid;
$dataResults = file_get_contents($teamResults);
$objResults[] = json_decode($dataResults, true);
}
The result is an array with this structure:
Array (
[0] => Array (
[errorcode] => 9995
[message] => No results
)
[1] => Array (
[errorcode] => 1000
[message] => Ok, Schedule follows
[List] => Array (
[0] => Array (
[MatchID] => 7683403
[Number] => 630
[Result] => 2 - 1
[Datum] => 2013-08-27
[Tijd] => 2000
[CompType] => B )
[1] => Array (
[MatchID] => 7683403
[Number] => 630
[Result] => 4 - 0 [Datum] => 2013-08-27
[Tijd] => 2000
[CompType] => B )
)
)
[2] => Array (
[errorcode] => 9995
[message] => No results )
)
Before saving it in an MySql database, for later use I need to add the teamID-variable to every result so it would become:
Array (
[0] => Array (
[errorcode] => 9995
[message] => No results
)
[1] => Array (
[errorcode] => 1000
[message] => Ok, Schedule follows
[List] => Array (
[0] => Array (
[teamID] => 'value from $teamID'
[MatchID] => 7683403
[Number] => 630
[Result] => 2 - 1
[Datum] => 2013-08-27
[Tijd] => 2000
[CompType] => B )
[1] => Array (
[teamID] => 'value from $teamID' [MatchID] => 7683403
[Number] => 630
[Result] => 4 - 0
[Datum] => 2013-08-27
[Tijd] => 2000
[CompType] => B )
)
)
[2] => Array (
[errorcode] => 9995
[message] => No results )
)
The length of the array varies and also the number of results vary. I have no influence on the result of the api-call itself, because it's been set up by big sport association.
I'm absolutely no programmer, so I'm out of my depth her, but this is a voluntary job for an amateur sportsclub so hiring a programmer is no option.

Answer 1

if(isset($objResults[1]['List'])){
foreach($objResults[1]['List'] as &$listItem){
$listItem['teamID'] = $teamID;
}
unset($listItem); //good practice to unset this reference to last array element
}
You could do the same with php's array_walk() function, but since you said you're not a programmer I think the foreach method is more clear to you.
