so in this post today we will learn how to extract all links of any web page with the help of PHP and will store all the links into MySQL database.
also make a URL extractor platform which will help us to analysis the website.

if some one is using WordPress website we can extract the URLs and check which kind of themes and plugins that website developers are used.
so just follow the below code an develop your own URL extractor.

function getAllLinks($url) {
$urlData = file_get_contents($url);
$dom = new DOMDocument();
$xpath = new DOMXPath($dom);
$hrefs = $xpath->evaluate("/html/body//a");
 for($i = 0; $i < $hrefs->length; $i++){
    $href = $hrefs->item($i);
    $url = $href->getAttribute('href');
    $url = filter_var($url, FILTER_SANITIZE_URL);
    if(!filter_var($url, FILTER_VALIDATE_URL) === false){
        $urlList[] = $url;  
return array_unique($urlList);

so in the above code we are just creating a PHP function that takes website URL as a parameter and fetch /extract all the links.
