我有这个代码:

$string1 = "My name is 'Kate' and im fine"; 
$pattern = "My name is '(.*)' and im fine"; 
preg_match($pattern , $string1, $matches);
echo $matches[1];

当我运行它时会返回此错误:

警告:preg_match()[function.preg-match]:分隔符不能是字母数字或反斜杠

我想用@ mywork.com限制我的电子邮件注册我在My_Form_validation中做了以下内容.

public function email_check($email)
    {
        $findme='mywork.com';
        $pos = strpos($email,$findme);
        if ($pos===FALSE)
        {
            $this->CI->form_validation->set_message('email_check', "The %s field does not have our email.");
            return FALSE;
        }
        else
        {
            return TRUE;
        }
    }

我用它如下.我对用户名和密码使用CI规则,它适用于电子邮件,它接受任何电子邮件地址.任何我感谢任何帮助.

function register_form($container)
    {
....

/ Set Rules
$config = array(
...//for username
// for email            
    array(
  'field'=>'email',
  'label'=>$this->CI->lang->line('userlib_email'),
  'rules'=>"trim|required|max_length[254]|valid_email|callback_email_check|callback_spare_email"
   ),
...// for password
 );

$this->CI->form_validation->set_rules($config);
