验证码验证不匹配请再试一次

Question

我的验证码验证问题。以下是newaccount文件中的一些代码。

当我尝试注册时说：

  

“您输入的验证码不匹配，请再试一次。

我有时会让它上班，那是在Chrome上，但它非常不稳定。

<?php session_start();
include ('connect.php');
require_once ('locale/'.$locale.'/'.$locale.'.php');
if(get_magic_quotes_gpc()) {
  $username = stripslashes(htmlspecialchars($_POST['usernames']));
  $password = stripslashes(htmlspecialchars($_POST['passwords']));
  $email = stripslashes(htmlspecialchars($_POST['email']));
  $security = stripslashes(htmlspecialchars($_POST['security']));
} else {
  $username = htmlspecialchars($_POST['usernames']);
  $password = htmlspecialchars($_POST['passwords']);
  $email = htmlspecialchars($_POST['email']);
  $security = htmlspecialchars($_POST['security']);
}
 if(strlen($security) < 4) {
  echo "<span class='infos alert'>$phrase[237] </span>";
  die();
 }
