What are the potential pitfalls of using PHP to scrape data from a website, especially when the data is loaded dynamically via AJAX?

When scraping data from a website that loads content dynamically via AJAX, the potential pitfalls include not being able to access the dynamically loaded content directly from the initial page source, as it may require additional requests to fetch the data. To solve this issue, you can use a headless browser like Puppeteer in combination with PHP to render the page and access the dynamically loaded content. 

<?php
require 'vendor/autoload.php';

use Nesk\Puphpeteer\Puppeteer;

$puppeteer = new Puppeteer();
$browser = $puppeteer->launch();
$page = $browser->newPage();
$page->goto('https://example.com');
// Wait for AJAX content to load
$page->waitForSelector('.ajax-loaded-content');
$content = $page->evaluate('document.querySelector(".ajax-loaded-content").textContent');

echo $content;

$browser->close();
?>
