php常用自建函数学习(4):ShowMsg返回弹出信息并进行返回、跳转、刷新等操作

if(!function_exists('ShowMsg'))
{
  function ShowMsg($msg='', $gourl='-1')
  {
    if($gourl == '-1')
      echo '<script>alert("'.$msg.'");history.go(-1);</script>';
    else if($gourl == '0')
      echo '<script>alert("'.$msg.'");location.reload();</script>';
    else
      echo '<script>alert("'.$msg.'");location.href="'.$gourl.'";</script>';
  }
}
