How to get Title and Meta tags from URL using PHP

There are 2 ways to get Meta Tags in PHP 1. get_meta_tags() function 2. Using cURL

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.

function GetMetaTag(){
	$meta_tags = get_meta_tags('https://tagstack.org/');
	print_r($meta_tags);
}

Get Title and Meta tags using cURL

function GetMetaTagCURL(){
	
	$url = "https://tagstack.org/";
 
	$html = file_get_contents_curl($url);
 
	$doc = new DOMDocument();
	@$doc->loadHTML($html);
 
	$nodes = $doc->getElementsByTagName('title');
	$title = $nodes->item(0)->nodeValue;
 
	$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". '

';
	echo "Description: $description". '

';
	echo "Keywords: $keywords";
}

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;
}
