, в частности, как бы получить миниатюры?

Answer 1

Я предлагаю вам начать читать о simpleXML

И если это не подходит вам, вы можете найти более понятное, но гораздо более простое учебное пособие здесь

Answer 2

Я не уверен, что вы используете разработанную мной библиотеку. Вот ссылка .Если это так, то есть параметр 'alt', который вы можете передать в библиотечный вызов, который позволит вам указать, как вы хотите, чтобы ваши данные возвращались.Если вы установите JSON, тогда вы можете использовать встроенную в PHP функцию json_decode.

Даже если вы не используете мою библиотеку, вы все равно можете использовать параметр alt, просто указав его в своем GET uri.
