An extremely fast and efficient web scraper that parses megabytes of HTML in a blink of an eye.

API Documentation


  • Very fast parsing and lookup
  • Parses broken HTML
  • jQuery-like style of DOM traversal
  • Low memory usage
  • Can handle big HTML documents (I have tested up to 20Mb, but the limit is the amount of RAM you have)
  • Doesn't require cURL to be installed
  • Automatically handles redirects (301, 302, 303)
  • Caches response for multiple processing tasks
  • PHP 5+
  • No dependencies


Just include_once 'hquery.php'; in your project and start using hQuery.

Alternatively composer require duzun/hquery

or using npm install hquery.php, require_once 'node_modules/hquery.php/hquery.php';.


Basic setup:

// Either use commposer, either include this file:
include_once '/path/to/libs/hquery.php';

// Optionally use namespaces (PHP >= 5.3.0 only)
use duzun\hQuery;

// Set the cache path - must be a writable folder
// If not set, hQuery::fromURL() whould make a new request on each call
hQuery::$cache_path = "/path/to/cache";

// Time to keed request data in cache, seconds
// A value of 0 disables cahce
hQuery::$cache_expires = 3600; // default one hour

Load HTML from a file

hQuery::fromFile( string $filename, boolean $use_include_path = false, resource $context = NULL )
// Local
$doc = hQuery::fromFile('/path/to/filesystem/doc.html');

// Remote
$doc = hQuery::fromFile('https://example.com/', false, $context);

Where $context is created with stream_context_create().

Fon an example of using $context to make a HTTP request with proxy see #26.

Load HTML from a string

hQuery::fromHTML( string $html, string $url = NULL )
$doc = hQuery::fromHTML('<html><head><title>Sample HTML Doc</title><body>Contents...</body></html>');

// Set base_url, in case the document is loaded from local source.
// Note: The base_url is used to retrive absolute URLs from relative ones
$doc->base_url = 'http://desired-host.net/path';

Load a remote HTML document

hQuery::fromUrl( string $url, array $headers = NULL, array|string $body = NULL, array $options = NULL )
use duzun\hQuery; // Optional (PHP 5.3+)

// GET the document
$doc = hQuery::fromUrl('http://example.com/someDoc.html', ['Accept' => 'text/html,application/xhtml+xml;q=0.9,*/*;q=0.8']);

var_dump($doc->headers); // See response headers
var_dump(hQuery::$last_http_result); // See response details of last request

// with POST
$doc = hQuery::fromUrl(
    'http://example.com/someDoc.html', // url
    ['Accept' => 'text/html,application/xhtml+xml;q=0.9,*/*;q=0.8'], // headers
    ['username' => 'Me', 'fullname' => 'Just Me'], // request body - could be a string as well
    ['method' => 'POST', 'timeout' => 7, 'redirect' => 7, 'decode' => 'gzip'] // options

For building advanced requests (POST, parameters etc) see hQuery::http_wr(), though I recomend using a specialized library for making requests and hQuery::fromHTML($html, $url=NULL) for processing results. See Guzzle for eg.

Another option is to use stream_context_create() to create a $context, then call hQuery::fromFile($url, false, $context).

Processing the results

hQuery::find( string $sel, array|string $attr = NULL, hQuery_Node $ctx = NULL )
// Find all banners (images inside anchors)
$banners = $doc->find('a > img:parent');

// Extract links and images
$links  = array();
$images = array();
$titles = array();

// If the result of find() is not empty
// $banners is a collection of elements (hQuery_Element)
if ( $banners ) {
    // Iterate over the result
    foreach($banners as $pos => $a) {
        $links[$pos] = $a->attr('href'); // get absolute URL from href property
        $titles[$pos] = trim($a->text()); // strip all HTML tags and leave just text

        // Filter the result
        if ( !$a->hasClass('logo') ) {
            $img = $a->find('img')[0]; // ArrayAccess
            if ( $img ) $images[$pos] = $img->src; // short for $img->attr('src')

    // If at least one element has the class .home
    if ( $banners->hasClass('home') ) {
        echo 'There is .home button!', PHP_EOL;

        // ArrayAccess for elements and properties.
        if ( $banners[0]['href'] == '/' ) {
            echo 'And it is the first one!';

// Read charset of the original document (internally it is converted to UTF-8)
$charset = $doc->charset;

// Get the size of the document ( strlen($html) )
$size = $doc->size;

Live Demo

On DUzun.Me

A lot of people ask for sources of my Live Demo page. Here we go:



  • Unit tests everything
  • Document everything
  • Cookie support (implemented in mem for redirects)
  • Use HTTPlug internally
  • Add more selectors
  • Improve selectors to be able to select by attributes
