頁面中用於JavaScript代碼的PHP簡單HTML DOM解析器

Question

我使用的是PHP Simple DOM解析器，HTML部分按預期工作，但是網頁的某些內容是用JavaScript顯示的。 JavaScript位於HTML頁面中，而不是單獨的文件，並且我需要的信息以純文本格式清晰顯示。 這是JavaScript代碼的開始方式，所需的信息位於結尾（位置）：

<script id="state">
    window.__INITIAL_STATE__ = {
        "detail": {
            "listingTopNavigation": {},
            "isTracked": false,
            "id": 30279925,
            "isImported": false,
            "isErotic": false,
            "isMessengerEnabled": false,
            "categories": [{
                "name": "Musique - Instruments",
                "id": 23,
                "isErotic": false
            }, {
                "name": "Guitares & Accessoires",
                "id": 697,
                "isErotic": false
            }, {
                "name": "Electrique",
                "id": 2354,
                "isErotic": false
            }],
            "imageData": {
                "baseUrl": "https:\u002F\u002Fcan01.anibis.ch\u002FElectrique-Line-6-DL-4-Delay-Modeler",
                "images": ["\u002F?[size]\u002Fanibis\u002F925\u002F279\u002F030\u002FLSmd7oN9LU6lAP5EbJQXXg_1.jpg", "\u002F?[size]\u002Fanibis\u002F925\u002F279\u002F030\u002Fhn2lNMOudUmuZofpM7wrsg_1.jpg", "\u002F?[size]\u002Fanibis\u002F925\u002F279\u002F030\u002FJKBbte21vEaD7ZJqcMi_Qg_1.jpg"]
            },
            "title": "Line 6 DL 4 Delay Modeler",
            "description": "\u003Cp\u003EVerkaufe mein Delay DL 6 in absolut neuwertigem Zustand wegen Nichtgebrauch. Das Delay habe ich im Dezember 2018 neu bei Musix gekauft und verfügt über eine tolle Auswahl an Delay Effekten, welche auf Fender Gibson Marshall oder Vox in Extraklasse daherkommen.

            "price": 190,
            "offerType": "Offer",
            "formattedPrice": "CHF 190.–",
            "formattedModified": "19.08.2019",
            "details": [{
                "name": "Remise",
                "value": "Retrait et envoi "
            }, {
                "name": "Type d’annonce",
                "value": "Offre"
            }],
            "location": {
                "country": "Suisse",
                "state": "Soleure",
                "zipCity": "4625 Oberbuchsiten (SO)"
            },

如何在PHP變量中獲取這些值以供以后使用。

$country = $html->find(...);
$state = $html->find(...);
$zip_city = $html->find(...);

謝謝。

if ($html) {

    if ($html->find('script[id=state]', 0)) {

        $script = $html->find('script[id=state]', 0);
        $script = ltrim($script, '<script id="state">window.__INITIAL_STATE__=');
        $script = rtrim($script, '</script>');

        $obj = json_decode($script, true);

        if (isset($obj['detail']['contact']['phone'])) {

            $tel = $obj['detail']['contact']['phone'];
            $tel = ltrim($tel, '+41 ');


            if (isset($obj['detail']['location']['street']))
                $address = trim($obj['detail']['location']['street']);

            if (isset($obj['detail']['location']['zipCity']))
                $npa_ville = trim($obj['detail']['location']['zipCity']);
                $npa_ville = explode(' ', $npa_ville, 2);
                $npa = preg_replace('/[^0-9]/', '', $npa_ville[0]);
                $ville = $npa_ville[1];
