  • Get title, description and image from meta tags using website url in laravel

    --PATH routes\web.php 
    Route::get('/get-content-url', function(){
    $url = 'https://oscarliang.com/';
    $resp = [];
    $ch = curl_init();
    curl_setopt($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);
    // Load HTML to DOM Object
    $dom = new DOMDocument();
    @$dom->loadHTML($data);
    
    // Parse DOM to get Title
    $nodes = $dom->getElementsByTagName('title');
    $title = '';
    if($nodes->length > 0){
        $title = $nodes->item(0)->nodeValue;
    }
    // Parse DOM to get Meta Description
    $metas = $dom->getElementsByTagName('meta');
    $body = "";
    $imageURL = "";
    for ($i = 0; $i < $metas->length; $i ++) {
        $meta = $metas->item($i);
        if ($meta->getAttribute('name') == 'Description' || $meta->getAttribute('name') == 'description') {
            $body = $meta->getAttribute('content');
        }
        if ($meta->getAttribute('property') == 'og:image:url') {
            $imageURL = $meta->getAttribute('content');
        }elseif($meta->getAttribute('property') == 'og:image'){
            $imageURL = $meta->getAttribute('content');
        }
    }

    $images = $dom->getElementsByTagName('img');

    if(!isset($imageURL) &amp;&amp; $images->length > 0){
        $imageURL = $images->item(0)->getAttribute('src');
    }
    
    $output = array(
        'title' => $title,
        'image_url' => $imageURL,
        'body' => preg_replace('/[^\00-\255]+/u', '', $body)
    );
    return $output; 
});
    0

    Output :

    {"title":"Oscar Liang - FPV Drone Tutorials and Reviews",
    "image_url":"https:\/\/oscarliang.com\/ctt\/uploads\/2021\/03\/oscarliang-fpv-drone-tutorial-review-blog-quadcopter-rc.jpg",
    "body":"FPV Drone Tutorials and Reviews, a blog for RC hobbyists to get latest information about quadcopter 
    and multirotor products and technology development, delivered to you by Oscar Liang."}

     This code snippet will return the title, description and image url from meta tags of the web page. If image does not exist with the meta property og:image and og:image:url within meta tags then it will get the first image from inside of the body tag of the web page.
