What are potential challenges faced when parsing and storing PDF links from a dynamic webpage using PHP?

When parsing and storing PDF links from a dynamic webpage using PHP, potential challenges include handling dynamic content loading through JavaScript, dealing with asynchronous requests, and ensuring the PDF links are correctly formatted and accessible. To solve this, you can use a headless browser like Puppeteer to render the page and extract the PDF links. This allows you to interact with the dynamic content and capture the links accurately. 

<?php

require 'vendor/autoload.php'; // Include Composer's autoloader

use Nesk\Puphpeteer\Puppeteer;

$puppeteer = new Puppeteer();
$browser = $puppeteer->launch();

$page = $browser->newPage();
$page->goto('https://example.com');

// Wait for the dynamic content to load
$page->waitForSelector('.pdf-link');

// Extract PDF links
$pdfLinks = $page->evaluate('Array.from(document.querySelectorAll(".pdf-link"), element => element.href)');

// Store the PDF links in a database or process them further
foreach ($pdfLinks as $link) {
    // Store the PDF link in a database or perform any other necessary action
}

$browser->close();
