<?php
$url = "https://techalltype.com/";
$html = file_get_contents($url);
$doc = new \DOMDocument('1.0', 'UTF-8'); /* instance of DOMDocument */
@$doc->loadHTML($html); /*The function parses the HTML contained in the string source */
$xpath = new \DOMXpath($doc); /*to retrieve selected html data */
$nodes = $xpath->query('//a');
foreach($nodes as $key => $node) {
echo $key++.".) ".$node->getAttribute('href')."<br/>";
