Fetch meta tags information from web URLs

sachin

I want to fetch meta information from web URLs

My current approach is

$url = "https://devsach.in/";
$tags = get_meta_tags($url);
echo "<pre>";
print_r($tags);

But with this I'm unable to get og: meta elements it's not mandatory to put name attribute in them but still I want them. How can I get it.

Simple approch, get it by curl

$url = "https://devsach.in/";

function file_get_contents_curl($url){
    $ch = curl_init();


    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);


    $data = curl_exec($ch);
    curl_close($ch);


    return $data;
}


$html = file_get_contents_curl($url);


//parsing begins here:
$doc = new DOMDocument();
@$doc->loadHTML($html);


$nodes = $doc->getElementsByTagName('title');
$title = $nodes->item(0)->nodeValue;


$tags = [];
$metas = $doc->getElementsByTagName('meta');
foreach ($metas as $element) {
    $tag = [];
    foreach ($element->attributes as $node) {
        $tag[$node->name] = $node->value;
    }
    $tags[] = $tag;
}

print_r($tags);

echo "Title: $title". '<br/><br/>';

This will output
