What are the potential pitfalls of regularly scraping content from a website every 10 minutes?

Regularly scraping content from a website every 10 minutes can lead to increased server load, potential IP blocking from the website being scraped, and violation of the website's terms of service. To solve this issue, consider implementing a caching mechanism to store scraped content locally and only scrape new content if necessary.

// Check if cached content exists and is not older than 10 minutes
if(file_exists('cached_content.txt') && (time() - filemtime('cached_content.txt') < 600)) {
    $content = file_get_contents('cached_content.txt');
} else {
    // Scrape new content from website
    $content = file_get_contents('https://example.com');
    
    // Save scraped content to cache
    file_put_contents('cached_content.txt', $content);
}

// Use $content variable for further processing
echo $content;
