How To Parse A Remote URL WebPage To Extract Desired Content Using PHP?

The below snipper with return a PHP variables is $webPageContent that is a plain string variable. Then we will instantiate the DOMDocument Class.

$webPageURL = "";

// Garb The WebPage Content
$ch = curl_init();
$timeout = 5; //5 is seconds
$userAgent = 'Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; .NET CLR 1.1.4322)';
curl_setopt($ch, CURLOPT_URL, $webPageURL);
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT,$timeout);
curl_setopt($ch, CURLOPT_HEADER, 1);
$webPageContent= curl_exec($ch);

// Parse The HTML Content
//Instantiate The DOMDocument Class
$htmlDom = new DOMDocument;
$htmlDom->validateOnParse = true;

//Parse the HTML of the page using DOMDocument::loadHTML In UTF8 Encoding
@$htmlDom->loadHTML(mb_convert_encoding($webPageContent, 'HTML-ENTITIES', 'UTF-8'));

Extract Links, HTML Tags, Images etc Everything From DOMDocument:

Here are some little examples of extracting all links with their attributes, extracting HTML tags, extracting IMG, etc that are self-explanatory .

// Extract All Links On The Web Page
//Extract the links from the HTML.
$links = $htmlDom->getElementsByTagName('a');

//Array that will contain our extracted links.
$extractedLinks = array();

//Loop through the DOMNodeList.
//We can do this because the DOMNodeList object is traversable.
foreach($links as $link){
	//Get the link text.
	$linkText = $link->nodeValue;

	//Get the link in the href attribute.
	$linkHref = $link->getAttribute('href');

	//Get the link in the rel attribute.
	$linkRel = $link->getAttribute('rel');

	//If the link is empty, skip it and don't
	//add it to our $extractedLinks array
	if(strlen(trim($linkHref)) == 0){

	//Skip if it is a hashtag / anchor link.
	if($linkHref[0] == '#'){

	//Add the link to our $extractedLinks array.
	$extractedLinks[] = array(
		'text' => $linkText,
		'href' => $linkHref,
		'rel' => $linkRel

// Extract <title> Tag
$titleTags = $htmlDom->getElementsByTagName("title");
foreach($titleTags as $titleTag){
	$extractedTitleTagText = $titleTag->nodeValue;

// Extract All Heading H1,H2,H3,H4,H5,H6 Tags
$tags = $htmlDom->getElementsByTagName('h1');
$extractedH1 = array();
foreach($tags as $tag){
	$tagsText = $tag->nodeValue;
	if(strlen(trim($tagsText)) == 0){
	$extractedH1[] = array(
		'tag' => "H1",
		'text' => $tagsText

// Extract All Image Alt-Title Tags
$tags = $htmlDom->getElementsByTagName('img');
$extractedIMG = array();
$extractedIMGaltCOUNT = 0;
$extractedIMGtitleCOUNT = 0;
foreach($tags as $tag){
	$tagsTextALT = $tag->getAttribute('alt');
	$tagsTextTITLE = $tag->getAttribute('title');
	$tagsTextSRC = $tag->getAttribute('src');
	if (strlen(trim($tagsTextALT)) == 0) {
	if (strlen(trim($tagsTextTITLE)) == 0) {
	$extractedIMG[] = array(
		'alt' => $tagsTextALT,
		'title' => $tagsTextTITLE,
		'src' => $tagsTextSRC
