Question

您好我正在尝试通过上传文本文件将数据导入mysql。我已经在不同的文件中写了文件上传和mysql导入代码，现在我正在尝试合并我的代码，我想上传文件，同时希望我的代码将其数据导入mysql数据库。我尝试在上传后粘贴导入代码，并将fopen('static-file')替换为fopen('$FILES_["file"],"r"')。但这没效果。

所以请告诉我如何同时上传和导入。

以下是我的上传代码：

<?php
 include_once 'dbconfig.php';
 if(isset($_POST['btn-upload']))
 {    

$file = rand(1000,100000)."-".$_FILES['file']['name'];
$file_loc = $_FILES['file']['tmp_name'];
$file_size = $_FILES['file']['size'];
$file_type = $_FILES['file']['type'];
$folder="uploads/";

// new file size in KB
$new_size = $file_size/1024;  
// new file size in KB

// make file name in lower case
$new_file_name = strtolower($file);
// make file name in lower case

$final_file=str_replace(' ','-',$new_file_name);

if(move_uploaded_file($file_loc,$folder.$final_file))
{
    $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
    mysqli_query($connection,$sql);


    ?>
    <script>
    alert('successfully uploaded');
   // window.location.href='index.php?success';
    </script>
    <?php


}
else
{
    ?>
    <script>
    alert('error while uploading file');
    window.location.href='index.php?fail';
    </script>
    <?php
  }

}

 ?>

这是我的MYSQL导入代码：

    <?php
    $con=mysqli_connect("localhost","root","","hiren");
    // Check connection
    if (mysqli_connect_errno())
      {
      echo "Failed to connect to MySQL: " . mysqli_connect_error();
      }


        $handle = fopen("./uploads/imp.dat", "r");
      if ($handle) {
          while (($line = fgets($handle)) !== false) {

               $lineArr = explode("\t", "$line");
               var_dump($lineArr); // to make sure array is ok

               // instead assigning one by onb use php list -> http://php.net/manual/en/function.list.php            
               list($emp_id, $date_data, $abc, $def, $entry, $ghi) = $lineArr;

               // and then insert data
               mysqli_query($con,"INSERT INTO `daily_data2` (emp_id, date_data, abc, def, entry, ghi) 
      VALUES ('$emp_id', '$date_data', '$abc', '$def', '$entry', '$ghi')");
          }

          fclose($handle);
      }

        ?>

显然开放fopen('$FILES_["file"],"r"')是不行的，因为那是一个数组（假设你当然是$_FILES["file"]。）即使你试图开放$_FILES["file"]["tmp_name"]它也不会工作 - 你认为move_uploaded_file()正在做什么？

<?php
include_once 'dbconfig.php';
if(isset($_POST['btn-upload'])) {
    $file = rand(1000,100000)."-".$_FILES['file']['name'];
    $file_loc = $_FILES['file']['tmp_name'];
    $file_size = $_FILES['file']['size'];
    $file_type = $_FILES['file']['type'];
    $folder="uploads/";

    // new file size in KB
    $new_size = $file_size/1024;  
    // new file size in KB

    // make file name in lower case
    $new_file_name = strtolower($file);
    // make file name in lower case

    $final_file=str_replace(' ','-',$new_file_name);

    if(move_uploaded_file($file_loc,$folder.$final_file)) {
        $sql="INSERT INTO tbl_uploads(file,type,size) VALUES('$final_file','$file_type','$new_size')";
        mysqli_query($connection,$sql);

        $handle = fopen($folder.$final_file, "r");
        if ($handle) {
            while (($line = fgets($handle)) !== false) {
                $lineArr = explode("\t", "$line");
                var_dump($lineArr); // to make sure array is ok
                // instead assigning one by onb use php list -> http://php.net/manual/en/function.list.php            
                list($emp_id, $date_data, $abc, $def, $entry, $ghi) = $lineArr;

                // and then insert data
                mysqli_query($con,"INSERT INTO `daily_data2` (emp_id, date_data, abc, def, entry, ghi) 
  VALUES ('$emp_id', '$date_data', '$abc', '$def', '$entry', '$ghi')");
            }
        fclose($handle);
    }
    ?>
    <script>
    alert('successfully uploaded');
   // window.location.href='index.php?success';
    </script>
    <?php
    }
    else {
    ?>
    <script>
    alert('error while uploading file');
    window.location.href='index.php?fail';
    </script>
    <?php
    }
}
?>

如何将相同的文件导入已上传的mysql？
