Welcome to the future of web scraping with hQuery.php! With its incredibly fast and efficient parsing capabilities, this tool is your best ally for extracting data from web pages. In this guide, we’ll walk you through installing, setting up, and using hQuery.php, along with some troubleshooting tips to keep your scraping adventures smooth and successful.

What is hQuery.php?

hQuery.php is a web scraping library that allows you to parse even broken HTML documents seamlessly. Utilizing a jQuery-like syntax, it lets you quickly find the data you need, proving to be faster and more efficient than Symfony’s DOMCrawler. It’s time to elevate your web scraping game!

Features of hQuery.php

• Extremely fast parsing and lookup
• Ability to handle broken HTML
• Low memory usage
• Can work with large HTML documents (up to 20Mb)
• No dependencies required

Installation

Getting started with hQuery.php is a breeze. You have two options:

• Add the hQuery folder to your project and include it with: include_once 'hquery.php';
• Or use Composer or npm to install it:

composer require duzun/hquery
npm install hquery.php

Basic Setup

Once installed, you need to set your cache path and specify the caching duration. The following code shows you how:

use duzunhQuery;

hQuery::$cache_path = 'path/to/cache';
hQuery::$cache_expires = 3600; // cache expires after one hour

Using hQuery.php

Now, let’s explore how to load HTML documents and find the data you need. Think of hQuery.php as a magic library where you can retrieve specific books (data) just by showing it where to look.

Loading HTML Documents

Whether the HTML is local, from a string, or remote, hQuery.php can handle it all:

Loading from a File

$doc = hQuery::fromFile('path/to/file.html'); // Local
$doc = hQuery::fromFile('https://example.com', false); // Remote

Loading from a String

$doc = hQuery::fromHTML('Contents...');

Loading a Remote Document

$doc = hQuery::fromUrl('http://example.com/someDoc.html');

Finding Data

After loading the document, you can search for specific elements using the find() method:

$banners = $doc->find('a[href] img[src]:parent');

You can then loop through the results to extract links, images, and text content.

Troubleshooting

If you encounter issues while using hQuery.php, here are some common troubleshooting tips:

• Ensure you have the correct path set for the cache directory.
• Check your PHP version; hQuery.php requires PHP 5.3 or greater.
• When loading remote documents, make sure the URL is accessible and correct.
• If you face encoding issues, ensure your HTML is properly encoded.
