使用 PHP Simple HTML DOM 提取脚本内容

Question

I want to extract the content of the script on this page , which has the ID __NEXT_DATA__ using PHP Simple HTML DOM , the code I wrote is this:

foreach($html_base->getElementsByTagName('script') as $element) {
                if (isset($element->id)){
                    $id = $element->id;
                    if ($id == "__NEXT_DATA__"){
                        $f = $element->nodeValue;
                        echo $f;
                        break;
                    }
                }
            
            }

but unfortunately it gives me the following error:

Undefined property: DOMElement::$id

Answer 1

You can use simple html dom documentation but here's my suggestion:

$html = file_get_html("url");
$script = $html->find("script[id=__NEXT_DATA__]", 0)->innertext;

the second parameter which is 0, is the index of the searched results and because it's only one script with this id, you can take the first result.
