Question

我有一个reviewfile.php，我根据我编码的条件阅读上传的文件并打印结果。

我想知道如何将我的页面结果放入文件中。这样我以后可以下载pdf。

以下是我的代码

if(isset($_POST['reviewFile'])){

    if (isset($_POST['fileSelected'])){

        $SelFile = $_POST['fileSelected'];

        echo "<b>Filename:</b> $SelFile";

        $query=$con->prepare("SELECT * from file where file_name = '$SelFile'");
        $query->bind_result($file_id, $uid, $file_name, $file_size);
        $query->execute();
        $query->fetch();
        $query->close();

        $path = 'C:/xampp/htdocs/fwrule/fw/fileuploads/';
        $file_to_get = $path.$SelFile;

        $_SESSION['tmpfname'] = $file_to_get;
        $_SESSION['excelReader'] = PHPExcel_IOFactory::createReaderForFile($_SESSION['tmpfname']);
        $_SESSION['excelObj'] = $_SESSION['excelReader']->load($_SESSION['tmpfname']);

        $_SESSION['worksheet'] = $_SESSION['excelObj']->getSheet(0);
        $_SESSION['lastRow'] =  $_SESSION['worksheet']->getHighestRow();
        $_SESSION['highestColumn'] = $_SESSION['worksheet']->getHighestColumn();

        //loop through each row of the worksheet in turn
        for ($_SESSION['row'] = 3; $_SESSION['row'] <= $_SESSION['lastRow']; ++$_SESSION['row']) {

            //read a row of data into an array
            $rowData = $_SESSION['worksheet']->rangeToArray('A'.$_SESSION['row']. ':'.$_SESSION['highestColumn'] . $_SESSION['lastRow'], NULL, TRUE, FALSE);

            //insert rows into database
            $InsertData = $con->prepare("INSERT INTO file_data(id, file_id, no, name, source, destination, hit_counts, service, action, track, install_on, time, comment)

您已经有查询可以找到存在问题的地方，那么为什么不使用NOT EXISTS ...

select fd1.id 
from file_data fd1
where not exists 
  (
  SELECT 1 FROM file_data fd2 WHERE (source collate latin1_swedish_ci = 'any' or destination collate latin1_swedish_ci ='any') and fd2.id = fd1.id
  )
and not exists
  (
  SELECT 1 FROM file_data fd3 WHERE comment = '' and fd3.id = fd1.id
  )
and not exists 
  (
  SELECT 1
  from file_data a
  join ( SELECT source, destination, hit_counts, service
      from file_data
      group by source, destination, hit_counts, service
      having count(*) > 1 ) b
    on a.source = b.source
  and a.destination = b.destination
  and a.hit_counts = b.hit_counts
  and a.service = b.service
  and a.id = fd1.id
  )
