Question

我尝试将包含完整数据的CSV文件导入phpMyAdmin数据库表。但是，只导入CSV文件中的部分数据。如果我在phpMyAdmin导入CSV文件，则导入所有数据。没有错误显示，我不太确定问题出现在哪里。我使用LOAD DATA INFILE将数据加载到数据库表中。

这是我的代码：

<?php

session_start();

$host       = "localhost";
$user       = "root";
$password   = "";
$db         = "smposi";

$con        = mysqli_connect($host,$user,$password,$db);

$message = "";
$m_sfile    = $_SESSION['sfile'];

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

     $allowed = array('csv');
     $filename = $_FILES['file']['name'];
     $ext = pathinfo($filename, PATHINFO_EXTENSION);
     if (!in_array($ext, $allowed)) 
     {
          // show error message
          $message = 'Invalid file type, please use .CSV file!';
     } 
     else 
     {

          move_uploaded_file($_FILES["file"]["tmp_name"], "Imported CSV/" . 
          $_FILES['file']['name']);

          $file = "Imported CSV/" . $_FILES['file']['name'];

          $query = <<<eof
          LOAD DATA LOCAL INFILE '$file'
          INTO TABLE $m_sfile
          FIELDS TERMINATED BY ',' 
          OPTIONALLY  ENCLOSED BY '"'
          LINES TERMINATED BY '\n'
          IGNORE 1 LINES
          (sdate2,sdate,location,pcode,code,custarea,
           pdesc,packet,weight,max,ppacket,lqty,printed,
           corder,luserid,ltime)
eof;


          $query2       = mysqli_query($con,"DELETE FROM $m_sfile WHERE 
          location=''");
          if (!$result = mysqli_query($con, $query)) 
          {
               exit(mysqli_error($con));
          }
          $message = "CSV file successfully imported!";
     }
}
?>

我使用以下简单脚本导入了CSV数据。如果这有帮助，请尝试一下。另请阅读complete article以便轻松导入/导出CSV数据。

if(isset($_POST["Import"])){

        $filename=$_FILES["file"]["tmp_name"];      


         if($_FILES["file"]["size"] > 0)
         {
            $file = fopen($filename, "r");
            while (($getData = fgetcsv($file, 10000, ",")) !== FALSE)
             {


               $sql = "INSERT into employeeinfo (emp_id,firstname,lastname,email,reg_date) 
                   values ('".$getData[0]."','".$getData[1]."','".$getData[2]."','".$getData[3]."','".$getData[4]."')";
                   $result = mysqli_query($con, $sql);
                if(!isset($result))
                {
                    echo "<script type=\"text/javascript\">
                            alert(\"Invalid File:Please Upload CSV File.\");
                            window.location = \"index.php\"
                          </script>";       
                }
                else {
                      echo "<script type=\"text/javascript\">
                        alert(\"CSV File has been successfully Imported.\");
                        window.location = \"index.php\"
                    </script>";
                }
             }

             fclose($file); 
         }
    }    


 ?>

尝试运行以下代码。

<?php
$databasehost = "localhost"; 
$databasename = "smposi"; 
$databasetable = "sample"; 
$databaseusername="test"; 
$databasepassword = ""; 
$fieldseparator = ","; 
$lineseparator = "\n";
$csvfile = "filename.csv";

if(!file_exists($csvfile)) {
    die("File not found. Make sure you specified the correct path.");
}

try {
    $pdo = new PDO("mysql:host=$databasehost;dbname=$databasename", 
        $databaseusername, $databasepassword,
        array(
            PDO::MYSQL_ATTR_LOCAL_INFILE => true,
            PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        )
    );
} catch (PDOException $e) {
    die("database connection failed: ".$e->getMessage());
}

$affectedRows = $pdo->exec("
    LOAD DATA LOCAL INFILE ".$pdo->quote($csvfile)." INTO TABLE `$databasetable`
      FIELDS TERMINATED BY ".$pdo->quote($fieldseparator)."
      LINES TERMINATED BY ".$pdo->quote($lineseparator));

   echo "Loaded a total of $affectedRows records from this csv file.\n";

?>

CSV文件中的数据仅部分导入phpMyAdmin数据库表
