title: How can I implement Google Recaptcha v3 in a PHP form?
body: <p>I would like to insert a contact form the new version (V3) of Recaptcha.</p>
  
  <p>I have looked for different solutions, but they only show part of the code, they are incomplete or I get an error, and most of the solutions found are very complicated for something so simple and I do not understand the code.</p>
