页面中用于JavaScript代码的PHP简单HTML DOM解析器

Question

I'm using PHP Simple DOM Parser, the HTML part is working as expected, but some of the content of the web page is shown with JavaScript. The JavaScript is within the HTML page not a separate file and the information I need is clear, in plain text. This is how the JavaScript code starts, the information needed is in the end (location):

<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.

            "details": [{
                "name": "Remise",
                "value": "Retrait et envoi "
            }, {
                "name": "Type d’annonce",
                "value": "Offre"
            }],
            "location": {
                "country": "Suisse",
                "state": "Soleure",
                "zipCity": "4625 Oberbuchsiten (SO)"
            },

How can I get these values in PHP variables to use after.

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

Thanks.

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];
