Get Meta tags using in-built function
Using the get_meta_tags() function we can extract the meta tags from the webpage. We need to pass the url in this function. This function returns the all <meta> tags until the closing </head> tag.
Let’s take an example for better understanding. Suppose we have an HTML head section as shown below.
index.html
1 2 3 4 5 6 7 8 9 | <html> <head> <title>Welcome to our website</title> <meta name="keywords" content="this is the keywords"> <meta name="description" content="this is the description"> </head> … … </html> |
index.php
1 2 3 4 5 6 7 8 9 10 11 | <?php $meta_tags = get_meta_tags('http://www.example.com/'); print_r($tags); ?> // Output: Array ( [keywords] => this is the keywords [description] => this is the description ) |
Get Title and Meta tags using cURL
In the above function, we can only get the meta tags using the get_meta_tags() function but can’t get the <title> tag. So now we will show you how to get the title and meta tags using cURL in PHP.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 | <?php 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; } $url = "'http://www.example.com/code"; $html = file_get_contents_curl($url); // Load HTML to DOM object $doc = new DOMDocument(); @$doc->loadHTML($html); // Parse DOM to get Title data $nodes = $doc->getElementsByTagName('title'); $title = $nodes->item(0)->nodeValue; // Parse DOM to get metadata $metas = $doc->getElementsByTagName('meta'); for ($i = 0; $i < $metas->length; $i++) { $meta = $metas->item($i); if($meta->getAttribute('name') == 'description') $description = $meta->getAttribute('content'); if($meta->getAttribute('name') == 'keywords') $keywords = $meta->getAttribute('content'); } echo "Title: $title". '<br/><br/>'; echo "Description: $description". '<br/><br/>'; echo "Keywords: $keywords"; ?> |
