Не могу выбрать значение массива, используя ключ с * _ в имени ключа
Я использую API, который возвращает объект, который я затем превращаю в массив для использования в моем API. Но я не могу выбрать значения, используя ключи, которые имеют * _ на их имени. Я не уверен почему. Вот как выглядит массив:
Array

И вот как я пытаюсь до него добраться ($tracking_dhl это массив выше):
$tracking_dhl_status = (array) $tracking_dhl["*_values"]["tracking_status"];
echo "Traking status: " . $tracking_dhl_status["_values:protected"]["status"] . "<br>";
Но я всегда получаю сообщение об ошибке, что ключ не существует.
Решение
Итак, я нашел обходной путь, как предложено в другом потоке, я изменил объект на массив, используя цикл foreach, где я взял ключ и удалил * _ и presto. Вот код:
public function toArray($obj) {
if (is_object($obj)) $obj = (array)$obj;
if (is_array($obj)) {
$new = array();
foreach ($obj as $key => $val) {
if (strpos(substr($key,0, 4), '_') !== false) {
$new[substr($key, 4)] = $this->toArray($val);
} else {
$new[$key] = $this->toArray($val);
}
//$new[str_replace("_", "", $key)] = $this->toArray($val);
}
} else {
$new = $obj;
}
return $new;
}
Эта функция помогла мне преобразовать объект в массив и изменить имя ключа, чтобы убрать символ * _, который в действительности использует 4 символа. Я до сих пор не понимаю этого. Тем не менее, с этим вы избавляетесь от надоедливых защищенных предметов в объекте, ха-ха. Я видел еще один с ltrim() вместо моего substr() и если дела, которые я сделал, но я не знаю, почему ltrim() не работал для меня. Надеюсь, это кому-нибудь поможет.
