Is it recommended to use third-party search engines like Google for PHP websites, and if so, what are the best practices for implementation?

It is recommended to use third-party search engines like Google for PHP websites as they provide more accurate and relevant search results. To implement this, you can use Google Custom Search Engine (CSE) which allows you to create a custom search engine for your website. Simply sign up for a CSE account, create a search engine, and then integrate the search box code into your PHP website. 

<!-- Google CSE Search Box Code -->
<form action="https://www.google.com/cse">
  <input type="hidden" name="cx" value="YOUR_SEARCH_ENGINE_ID">
  <input type="hidden" name="ie" value="UTF-8">
  <input type="text" name="q" size="31">
  <input type="submit" name="sa" value="Search">
</form>
