Я пытаюсь получить изображение src из Atom Feed на основе XML, используя PHP. Я хочу сделать это, разрезав строку в фиде так, чтобы захватывался только URL.
До сих пор я мог использовать команду substr() для нарезания определенной длины строки. Проблема заключается в том, что длина URL-адреса изображения в канале будет часто варьироваться, поэтому мне нужно нарезать фрагмент на основе определенного символа.
Я попытался использовать Explode, чтобы указать символ для нарезки:
foreach ($array['entry'] as $post) {
if ($current > $max) break;
$posts[] = [
'post_img' => explode("\"", $post['content'], 2),
... но это не сработало. Вот код XML, из которого я пытаюсь получить:
<content type="html"><img alt="" class="attachment image image" src="http://awpagesociety.com/attachments/20aa91b841d6a49dd945a97af37509add2680573/store/limit/452/300/e6941ac426f6cbca5774cad6f2e8b6447c96d92d32957be6709dac201de7/Brady-Bush.jpg"
А вот и метод в полном объеме. Поля url, post_content и post_title назначаются правильно:
$feed = getRssFile();
if ($feed == false) return;
$xml = simplexml_load_file($feed);
$json = json_encode($xml);
$array = json_decode($json,TRUE);
$posts = [];
if (count($array['entry'])) {
$max = 3;
$current = 1;
foreach ($array['entry'] as $post) {
if ($current > $max) break;
$posts[] = [
'post_img' => explode("src=", $post['content'], //isn't working
'post_title' => $post['title'],
'post_content' => substr(sanitizeContent($post['content']), 0, 200),
'url' => $post['link']['@attributes']['href']
];
$current++;
}
}
return $posts;
}
explode () ничего не назначает полю src изображения, когда я проверяю в инспекторе элементов. Он просто говорит img src(unknown) Есть ли какие-нибудь альтернативы для получения нужного мне результата?
РЕДАКТИРОВАТЬ: вот что возвращается от выполнения
$exp = explode("src=", $thing);
var_dump($exp[1]);
var_dump($exp);
Результат:

И я хочу просто вернуть каждый источник изображения отдельно, например
"http://awpagesociety.com/attachments/c881c9ec924cfd1ee7f0650f2b6de9b36d4e31a9/store/limit/452/300/25f7a5696d2bd1d5e4d1137924ff04e3e2c8333fa8c71e005462a4e710d9/Walker_Recording.jpg", "http://awpagesociety.com/attachments/20aa91b841d6a49dd945a97af37509add2680573/store/limit/452/300/e6941ac426f6cbca5774cad6f2e8b6447c96d92d32957be6709dac201de7/Brady-Bush.jpg"
В основном хотят вырезать весь другой контент, например текст между тегами стиля и другим форматированием.
