复制代码 代码如下:

require_once("Zend/Loader.php");
//引入校验器类和效验器的功能类(Int),与自定义接口类;
Zend_Loader::loadClass('Zend_Validate');
Zend_Loader::loadClass('Zend_Validate_Int');
Zend_Loader::loadClass('Zend_Validate_Interface');
//增加自定义校验器功能类(GongBeiNum)[公倍数]
Class GongBeiNum implements Zend_Validate_Interface
{
 //声明接口里的错误信息报告属性
 protected $_messages = array();
 //声明接口里的校验方法
 public function isValid($num)
 {
  if (!($num%3==0) && !($num%5==0))
  {
   //如果校验失败,则讲错误信息返回值给错误信息报告属性
   $this -> _messages[] = "你所输入的数值不是3和5的公倍数!";
   //终止程序
   return false;
  }
  //返回真
  return true;
 }
 //定义接口的报错方法
 public function getMessages()
 {
  return $this -> _messages;
 }
 //定义提取错误信息(可无)
 public function getErrors()
 {

 }
}
//类外定义检测公倍数方法
function check_num($num)
{
 //实例化校验器类
 $Validate = new Zend_Validate();
 //添加校验器功能功能类、添加自定义校验器功能类,形成校验器链
 $Validate -> addValidator(new Zend_Validate_Int())
     -> addValidator(new GongBeiNum());
 //校验参数
 if (!$Validate -> isValid($num))
 {
  //如果错误循环错误信息并输出
   foreach ($Validate -> getMessages() as $value)
   {
    echo $value . "
";
    return false;
   }
 }
}

//指定判断的值
$num1 = '15';
//运行校验方法
check_num($num1);
?>
