404页面自动调用，404 php错误

插入查询后，结果如下

$ipvisitor = $_SERVER['REMOTE_ADDR'];
  $prevpage = $_SERVER['HTTP_REFERER'];
  $urlpage = $_SERVER['PHP_SELF'];
// $urlpage = $_SERVER['SCRIPT_NAME'];  this is also used
  $urlcount = explode("/",$urlpage);
  $naem = end($urlcount);
  $finalurl = substr($naem, 0, -4);

  $date =date("d-m-Y");
  $serverName = "______"; //serverName
  $connectionInfo = array(_____);
  $conn = sqlsrv_connect( $serverName, $connectionInfo);
  if( $conn ) {
    $tsql = "INSERT INTO [dbo].[tttt]
         ([cPageName],[ipadd],[dtcreatedDate],[date],[prevpage])
   VALUES
         ('$finalurl','$ipvisitor',getdate(),'$date','$prevpage')";

这个页面也被插入了，但我不明白为什么404会像访问过的页面一样出现

您的代码容易受到攻击。请始终使用with，而不是使用字符串连接生成查询。有关一些好的示例，请参见和。
