Вопрос:
Я работаю над проектом, который использует codeigniter и API youtube, я делаю запрос на видео, и я получаю некоторый XML обратно, моя проблема в том, что я понятия не имею, что делать с указанным XML или, точнее, как его проанализировать, чтобы я мог добраться дозначения, которые я хочу, XML, который я получаю обратно,

в частности, как мне получить эскизы?
Ответ №1:
Я предлагаю вам начать читать о SimpleXML
И если это вам не подходит, вы можете найти более понятный, но намного более простой учебник прямо здесь
Ответ №2:
Я не уверен, используете ли вы библиотеку, которую я разработал. Вот ссылка. Если да, то есть параметр ‘alt’, который вы можете передать в вызов вашей библиотеки, который позволит вам указать, как вы хотите, чтобы ваши данные возвращались. Если вы установите для него значение JSON, вы можете использовать встроенную в PHP функцию json_decode.
Даже если вы не используете мою библиотеку, вы все равно можете использовать параметр alt, просто укажите его в своем GET uri.
