Array Showing Values from previous iteration - php

Question

I have this code using an api , the first iteration is showing everything right , but at the second iteration is showing the items from the first iteration + the items from the second iteration , and the same thing at the third iteration.
I dont want that , how can i fix that problem ?
$g=0;
foreach ($matches as $match) {
$inside = $api->getMatch('123');
$pp = $api->getMatchTimeline('123');
foreach ($inside->participants as $partId) {
if ($partId->championId == $match->champion) {
$participant_id[] = $partId->participantId;
$participant_idS = $partId->stats->participantId;
foreach ($pp->frames as $p) {
foreach ($p->events as $t) {
if ($t->type == "ITEM_PURCHASED" and $t->participantId == $participant_idS) {
$item_id = $t->itemId;
$d = $api->getStaticItem($item_id);
if($d->depth == 2 or $d->depth == 3){
$itemsMade[] = $d->id;
}
}
}
}
}
}
$dt = [['match_ids' => $part, "champion" => $soloq->champion, "timestamp" => $match->timestamp, "participantId" => $participant_id[$g++], "itens" => json_encode($itemsMade)]
];
echo ' <pre>';
var_dump($dt);
echo '</pre>';
}

You need to set that array to be empty at the start of your loop. Otherwise you just keep adding to it as you see in your output.
foreach ($inside->participants as $partId) {
$itemsMade = [];
