      $default = "https://www.somewhere.com/homestar.jpg";
      $size = 50;
      $grav_url = "https://www.gravatar.com/avatar/" . md5( strtolower( trim( $email ) ) ) . "?d=" . urlencode( $default ) . "&s=" . $size;
    ?>

Answer 1

function isGravatar($email) {
  $uri = 'https://www.gravatar.com/avatar/' . md5($email) . '?d=404';
  $headers = get_headers($uri);
  return (bool) preg_match("|200|", $headers[0]);
}
// isGravatar('[email protected]');

Found solution on google

<?php
      $email = $review['email'];
      $hash = md5($email);
      $uri = 'http://www.gravatar.com/avatar/' . $hash . '?d=404';
      $default = "https://www.somewhere.com/homestar.jpg";
      $size = 50;
      $headers = @get_headers($uri);
      if (!preg_match("|200|", $headers[0])){
        $grav_url = "catalog/view/theme/tbchoice/img/comment2.jpg";
      } else {
          $grav_url = "https://www.gravatar.com/avatar/" . md5( strtolower( trim( $email ) ) ) . "?d=" . urlencode( $default ) . "&s=" . $size;
      } 
    ?>
