# Tips-6) How to get meta Tag

Returns an array with all the parsed meta tags.

The value of the name property becomes the key, the value of the content property becomes the value of the returned array, so you can easily use standard array functions to traverse it or access single values. Special characters in the value of the name property are substituted with '_', the rest is converted to lower case. If two meta tags have the same name, only the last one is returned.

Returns false on failure.

index.php
Example: PHP 
<?php
// Assuming the above tags are at www.example.com
$tags = get_meta_tags('https://www.metkovicnet.com');

// Notice how the keys are all lowercase now, and
// how . was replaced by _ in the key.
echo $tags['author'];       // name
echo '</br>';
echo $tags['keywords'];     // php documentation
echo '</br>';
echo $tags['description'];  // a php manual

# Tips-7) How to get title description image and multiple images from URL

The following PHP code shows how to get page titles and other meta details by using  PHP CURL. In this code, I initialized the CURL object and set the URL to be accessed with the reference of this object. The CURL script will return the HTML content of the remote page.

After getting the HTML content, we need to parse the HTML by referring to the title, meta and img tag names to get the page title, description and the image URLs, respectively. These data are encoded into a JSON array and returned as the AJAX response.

Full Code

Just download index.php and run into your website.

You can change the url horje.com and put your once.

index.php
Example: PHP 
<?php
$url = "https://horje.com/learn/757/clipbucket";

    // Extract HTML using curl
    $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 = $nodes->item(0)->nodeValue;
    
    // Parse DOM to get Meta Description
    $metas = $dom->getElementsByTagName('meta');
    $body = "";
    for ($i = 0; $i < $metas->length; $i ++) {
        $meta = $metas->item($i);
        if ($meta->getAttribute('name') == 'description') {
            $body = $meta->getAttribute('content');
        }
    }
    
    // Parse DOM to get Images
    $image_urls = array();
    $images = $dom->getElementsByTagName('img');
     
     for ($i = 0; $i < $images->length; $i ++) {
         $image = $images->item($i);
         $src = $image->getAttribute('src');
         
         $m_i .= ''.$src.'</br>';
     }
echo $title;
echo '</br>';
echo $body;
