Выберите ID из массива в PHP

у меня есть следующий массив:

Это должно дать вам некоторое вдохновение; я сократил Ваш массив и поместил его в одинарные кавычки в первой строке:

	$json=

Он генерирует

1000016558 = 11355797905

1000014684 = 11355887514

1000016559 = 4750866162


и это должно помочь тебе начать.

Fynn Pfingsten

Привет, Спасибо! Это работает. У меня есть еще один вопрос, у меня есть еще один массив, который не имеет тега "[" в начале. Он начинается непосредственно с "{". Проблема в том, что в результате получается много тегов"=".

Luc Pattyn

Это был ваш пятый вопрос.
Каждый раз, когда на вопрос "что я пробовал" отвечали что-то вроде "искал в google, но не нашел решения проблемы"

Вы не показываете ни кода, ни сообщений об ошибках, ничего. Никаких признаков того, что ты действительно что-то пытаешься сделать.

А теперь скажите мне, что код, который я вам дал, или какой-то его вариант, "работает". Я хочу услышать, что вы провели некоторые исследования и теперь понимаете, почему и как это работает. Тогда вы добились бы некоторого прогресса и были бы лучше подготовлены к ответам на свои собственные вопросы...


Если вы новичок в программировании, или в языке, или в каком-то конкретном аспекте программного обеспечения, то начните с чтения нескольких глав в книге на эту тему. Сделайте усилие, попытайтесь научиться. Мы здесь не для того, чтобы кормить вас с ложечки.

Удачи.

Fynn Pfingsten

Спасибо за ваш ответ! Google или другие платформы не дают мне ответа. Спасибо большое за ваш код, вы мне очень помогли. и я попытался решить эту проблему сам с помощью нового массива, но не получил его. потому что [ отсутствует в начале, и я не знаю, как работает декодирование массива. так ты можешь мне помочь или нет?

Luc Pattyn

Почему вы настаиваете на том, чтобы называть его массивом, вы же сами сказали, что он не начинается с скобки.
Вы вообще знаете, что такое JSON? вы читали документацию по json_decode?
сделайте некоторые исследования, пока вы этого не сделаете, я больше не буду отвечать.

Fynn Pfingsten

Вот код, который я пробовал, но он не работает, пожалуйста, помогите мне решить эту проблему!

Fynn Pfingsten

Я читал статью о json поэтому думаю что знаю что это такое

В вашем массиве есть много идентификаторов, поэтому я не уверен, на какой из них вы ссылаетесь.

Кроме того, вы не упомянули, где хранится массив, в сеансе или другом месте?

Вызов ключа и значения массива -

$myArray = $_SESSION['theIDname'];
echo $myArray;


Также не говоря уже о том, хотите ли вы получить все идентификаторы массива или только определенный, циклический или нет.
