php如何禁止查看代码（方法如下）

<Files *.php>
  Order deny,allow
  Deny from all
</Files>

class SecretCode {
   private $code = "php代码";
   function showCode($password) {
      if($password != "mypassword") {
         exit("访问被拒绝");
      }
      echo "$this->code";
   }
}
 
$myCode = new SecretCode();
$myCode->showCode("mypassword");
