Web Scraping is evolving every day. There are new methods and new libraries every day for making web scraping fun and easy. First, let’s understand why we do web scraping, and then we will focus on the top 5 PHP libraries that can help you scrape websites quickly.

Why do we do web scraping?
There are several reasons why web scraping may be required:
- Data collection: Web scraping can be used to collect large amounts of data from websites, such as product names, prices, and reviews, which can then be used for data analysis or to train machine learning models.
- Competitive analysis: Web scraping can be used to gather data about competitors, such as their product offerings, prices, and marketing strategies, which can help a business make more informed decisions.
- Price comparison: Web scraping can be used to gather data from multiple online retailers to compare prices and find the best deals.
- Lead generation: Web scraping can be used to gather data from websites and social media profiles to build lists of potential leads for sales and marketing teams.
- Content aggregation: Web scraping can be used to gather data from multiple sources and combine it into a single, easy-to-use format, such as an aggregated news feed or a directory of information.

Top 5 web scraping PHP libraries
Goutte
Goutte is a PHP library that can be used for web scraping. It is based on the Guzzle HTTP client library, and it provides a simple interface for making HTTP requests and parsing the responses.
To use Goutte, you will need to install it using Composer, the dependency manager for PHP. Here is an example of how to install Goutte using Composer:
composer require fabpot/goutte
Once Goutte is installed, you can use it to scrape a website & extract data by making an HTTP request to the URL of the page you want to scrape, and then using the DOM crawler to select and extract the data you need.
Here is an example of how to use Goutte to scrape a webpage and extract the text of all the links on the page:
<?php
require 'vendor/autoload.php';
use Goutte\Client;
$client = new Client();
// Make a request to the website
$crawler = $client->request('GET', 'http://books.toscrape.com/');
// Extract the text of all the links on the page
$crawler->filter('a')->each(function ($node) {
echo $node->text() . "\n";
});
This code makes an HTTP GET request to the website at “http://books.toscrape.com/“, and then uses the DOM crawler to select all the “a” elements (links) on the page. It then iterates over each link and extracts the text of the link using the “text()” method. Goutte provides many other methods for making HTTP requests, selecting elements from the DOM, and extracting data from the page. You can refer to the Goutte documentation for more information.
HTTPful
HTTPful is a PHP library that can be used to make HTTP requests and parse HTTP responses. It supports Basic Auth, custom headers, etc. It can be used for web scraping by making HTTP requests to the URL of the page you want to scrape and then parsing the response to extract the data you need.
To use HTTPful, you will need to install it using Composer, the dependency manager for PHP. Here is an example of how to install HTTPful using Composer:
composer require nategood/httpful
Once HTTPful is installed, you can use it to make HTTP requests and parse the responses. Here is an example of how to use HTTPful to make a GET request to a website and parse the response:
<?php
require 'vendor/autoload.php';
use Httpful\Request;
// Make a GET request to the website
$response = Request::get('http://books.toscrape.com/')->send();
// Check the status code of the response
if ($response->code == 200) {
// The request was successful, so you can parse the response body
$html = $response->body;
// Extract the data you need from the HTML using PHP's DOM extension or a library like PHP Simple HTML DOM Parser
} else {
// There was an error making the request or parsing the response
}
HTTPful provides many other methods for making different types of HTTP requests, such as POST, PUT, and DELETE, and for setting request headers and parameters. You can refer to the HTTPful documentation for more information.
Guzzle
Guzzle is another PHP HTTP client library that can be used to make HTTP requests and parse HTTP responses. Using Guzzle you send both synchronous and asynchronous requests. It can be used for web scraping by making HTTP requests to the URL of the page you want to scrape and then parsing the response to extract the data you need.
To use Guzzle, you will need to install it using Composer, the dependency manager for PHP. Here is an example of how to install Guzzle using Composer:
composer require guzzlehttp/guzzle
Once Guzzle is installed, you can use it to make HTTP requests and parse the responses. Here is an example of how to use Guzzle to make a GET request to a website and parse the response:
<?php
require 'vendor/autoload.php';
use GuzzleHttp\Client;
$client = new Client();
// Make a GET request to the website
$response = $client->get('http://books.toscrape.com/');
// Check the status code of the response
if ($response->getStatusCode() == 200) {
// The request was successful, so you can parse the response body
$html = (string) $response->getBody();
// Extract the data you need from the HTML using PHP's DOM extension or a library like PHP Simple HTML DOM Parser
} else {
// There was an error making the request or parsing the response
}
Guzzle provides many other methods for making different types of HTTP requests, such as POST, PUT, and DELETE, and for setting request headers and parameters. You can refer to the Guzzle documentation for more information.
cURL
cURL is a command-line tool for making HTTP requests and receiving responses. It can be used for web scraping in PHP by making HTTP requests to the URL of the page you want to scrape and then parsing the response to extract the data you need.
To use cURL in PHP, you will need to have the cURL extension installed and enabled in your PHP configuration. You can check if cURL is installed and enabled by running the following code:
<?php
if (function_exists('curl_version')) {
echo "cURL is installed and enabled\n";
} else {
echo "cURL is not installed or enabled\n";
}
If cURL is installed and enabled, you can use it to make HTTP requests and parse the responses. Here is an example of how to use cURL to make a GET request to a website and parse the response:
<?php
// Set up the cURL request
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://books.toscrape.com/');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Make the request and get the response
$response = curl_exec($ch);
$status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
// Check the status code of the response
if ($status_code == 200) {
// The request was successful, so you can parse the response body
$html = $response;
// Extract the data you need from the HTML using PHP's DOM extension or a library like PHP Simple HTML DOM Parser
} else {
// There was an error making the request or parsing the response
}
// Close the cURL handle
curl_close($ch);
cURL provides many other options for setting request headers, handling cookies, and following redirects. You can refer to the cURL documentation for more information.
Requests
Requests is a PHP library that simplifies making HTTP requests and parsing HTTP responses. It can be used for web scraping by making HTTP requests to the URL of the page you want to scrape and then parsing the response to extract the data you need.
To use Requests, you will need to install it using Composer, the dependency manager for PHP. Here is an example of how to install Requests using Composer:
composer require rmccue/requests
Once Requests is installed, you can use it to make HTTP requests and parse the responses. Here is an example of how to use Requests to make a GET request to a website and parse the response:
<?php
require 'vendor/autoload.php';
use Requests;
// Make a GET request to the website
$response = Requests::get('https://www.example.com');
// Check the status code of the response
if ($response->status_code == 200) {
// The request was successful, so you can parse the response body
$html = $response->body;
// Extract the data you need from the HTML using PHP's DOM extension or a library like PHP Simple HTML DOM Parser
} else {
// There was an error making the request or parsing the response
}
Requests provide many other methods for making different types of HTTP requests, such as POST, PUT, and DELETE, and for setting request headers and parameters. You can refer to the Requests documentation for more information.
