页面中用于JavaScript代码的PHP简单HTML DOM解析器

Question

我使用的是PHP Simple DOM解析器，HTML部分按预期工作，但是网页的某些内容是用JavaScript显示的。 JavaScript位于HTML页面中，而不是单独的文件，并且我需要的信息以纯文本格式清晰显示。 这是JavaScript代码的开始方式，所需的信息位于结尾（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变量中获取这些值以供以后使用。

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

谢谢。

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];
