同じイベントを数えようとしています。たとえば、["イベント"] = 開く =4 / ["イベント"] = クリック =1 です。

foreachループをカウントすることでこれを達成しようとしています:

$i=0;
foreach($entry->Actions as $actions ) { 
echo $i++;          
}

これにアプローチする方法がよくわかりませんか？誰かがベストプラクティスを提案できますか?

$counts = array();

foreach($entry->Actions as $actions) {
    if(!isset($counts[$actions->Event])) {
        $counts[$actions->Event] = 0;
    }
    ++$counts[$actions->Event];
}

print_r($counts);

<?php
$amounts = array(); // Events as key
foreach($entry->Actions as $actions)
{
    if (isset($amounts[$actions["Event"]])) $amounts[$actions["Event"]]++;
    else $amounts[$actions["Event"]] = 1;
}
print_r($amounts);
echo "<br>".$amounts["Open"];
?>
