How to Scrape Dynamic Websites in PHP (JavaScript Content Guide)

Introduction

In this guide, I will teach how to scrape dynamic websites in PHP using practical and real-world approaches.

What is Dynamic Content?

Dynamic content refers to data that is loaded after the page is rendered using JavaScript. This means the data is not available in the initial HTML response.

Why PHP cURL Fails for Dynamic Content

PHP cURL only fetches raw HTML from the server and does not execute JavaScript. That’s why it cannot capture dynamically loaded content.

How to Identify Dynamic Content

  • Content loads after page load
  • Data is missing in page source
  • Network tab shows API calls

Method 1: Use Website APIs (Best Approach)

Most modern websites load data via APIs. You can inspect network requests and directly fetch data using PHP.


<?php
$url = "https://api.example.com/data";
$response = file_get_contents($url);
echo $response;
?>

Method 2: Use Headless Browsers

For JavaScript-heavy websites, tools like Puppeteer or Playwright can render content before scraping.

Method 3: Use Scraping APIs

Services like ScraperAPI can fetch fully rendered HTML without handling JavaScript manually.
