直接在php中验证可以验证
$value = '电商';preg_match('/^[a-za-z\x{4e00}-\x{9fa5}][a-za-z_\-\x{4e00}-\x{9fa5}]*$/u',$value,$m)

在phalcon的控制器的方法中就不能验证，
public function registeraction() { if($this->request->ispost()) { $myvalidator = new myvalidator(); $errors = $myvalidator->validateusername($this->request->getpost('user_name')); } }

下面是调用的函数，
public function validateusername($value) { $error = false; if(!preg_match('/^[a-za-z\x{4e00}-\x{9fa5}][a-za-z_\-\x{4e00}-\x{9fa5}]*$/u',$value,$m)) { $error = true; print_r('world'); } else { $pattern = '/[\x{4e00}-\x{9fa5}]/u'; $str1 = preg_replace($pattern, '', $value, -1, $count); $length = strlen($str1) + $count * 2; if (!($length >= 2 && $length 'user name is invalid2.']; } else { $return = null; } return $return; }
