Answer 1

developers.google.com有一个非常好的文档，说明如何使用recaptcha与php：

Answer 2

可能的解决方案是使用任何可用的php库。这是一个友好的API，名为 Securimage 有一个PHP脚本可供使用，很少有类可用于生成验证码图像并验证它们。用于验证输入的示例代码

include_once 'securimage.php';
$securimage = new Securimage();
if ($securimage->check($_POST['captcha_code']) == false) {
  echo "The security code entered was incorrect.<br /><br />";
  echo "Please go <a href='javascript:history.go(-1)'>back</a> and try again.";
  exit;
}
