What are potential challenges when trying to extract data from a website using PHP?

One potential challenge when trying to extract data from a website using PHP is handling dynamic content loaded via JavaScript. To solve this, you can use a headless browser like Puppeteer to render the page and then extract the data. 

// Example using Puppeteer to extract dynamic content from a website
$cmd = 'node puppeteer_script.js'; // Command to run Puppeteer script
$output = shell_exec($cmd); // Execute the command
$data = json_decode($output, true); // Parse the output as JSON data

// Now you can access the extracted data
var_dump($data);
