我需要從最高計數排序foreach，例如首先計數5，計數4秒，等等......
$i = 0;
$diseases = Diseases::find()->localized($lang)->all();
foreach ($diseases as $disease) {
$selected_symptoms_array = explode(',', $symptoms);
$symptoms_array = explode(',', $disease->symptoms_id);
if (count(array_intersect($selected_symptoms_array, $symptoms_array)) > 0){
$data[$i]['translation']['title'] = $disease->title;
$data[$i]['id'] = $disease->id;
$data[$i]['count'] = count(array_intersect($selected_symptoms_array, $symptoms_array));
$i ;
}
}
uj5u.com熱心網友回復：
解決方案：
ArrayHelper::multisort($data, function ($item) {
return isset($item['count']) ? $item['count'] : $item['id'];
}, SORT_DESC);
更新：這是 yii2 檔案中的標準功能。它在 foreach 之后按給定的鍵對陣列進行排序
