使用PHP將CSV文件上傳到數據庫時出錯

[英]Error when uploading CSV file to database using PHP

我正在嘗試使用PHP將CSV文件上傳到數據庫中的現有表中。

這是我的完整代碼:

<?php
include("detail.php");


 $connect = mysql_connect("$host", $user, $password) or die("Couldn't connect to SQL  Server on $myServer");
 mysql_select_db("$database") or die("Couldn't open database $myDB");

 if (mysqli_connect_errno())
 {
 echo "Failed to connect to MySQL: " . mysql_connect_error();
 }


 define('CSV_PATH','E:/4th Year/FYP/'); // specify CSV file path

  $csv_file = CSV_PATH . "Cash2011.csv"; // Name of your CSV file
 $csvfile = fopen($csv_file, 'r');
 $theData = fgets($csvfile);
 $i = 0;
 while (!feof($csvfile))
 {
   $csv_data[] = fgets($csvfile, 1024);
   $csv_array = explode(",", $csv_data[$i]);
   $insert_csv = array();
   $insert_csv['cashAmount'] = $csv_array[0];
   $insert_csv['cashReceivedDate'] = $csv_array[1];
   $insert_csv['customerID'] = $csv_array[2];
   $insert_csv['invoiceNo'] = $csv_array[3];
   $insert_csv['monthNum'] = $csv_array[4];
   $insert_csv['yearNum'] = $csv_array[5];
   $query = "INSERT INTO cash2011(cashAmount,cashReceivedDate,invoiceNo,monthNum,yearNum) VALUES ('','".$insert_csv['cashAmount']."','".$insert_csv['cashReceivedDate']."','".$insert_csv['customerID']."','".$insert_csv['invoiceNo']."','".$insert_csv['monthNum']."','".$insert_csv['yearNum']."')";
   $n=mysql_query($query, $connect);
   $i++;
   }
   fclose($csvfile);
   echo "File data successfully imported to database!!";
   ?>

這些是我一直收到的錯誤:未定義的偏移量:第47行的C:\\ Apache2.2 \\ htdocs \\ clearTables.php中的1($ insert_csv ['cashAmount'] = $ csv_array [0];)。 未定義的偏移量:第48行的C:\\ Apache2.2 \\ htdocs \\ clearTables.php中的2。

有人知道問題出在哪里嗎? 謝謝

我測試了您的代碼,並且工作得非常好……並且,當我回顯查詢時,返回:

    INSERT INTO cash2011(cashAmount,cashReceivedDate,invoiceNo,monthNum,yearNum) 
VALUES ('','ad4213','ad4214','ad4215','ad4216','adware','ad7777 ')
    //'','ad4213','ad4214','ad4215','ad4216','adware','ad7777 ' -> data in my example csv file

一些事情..我相信您的文件不存在,這就是為什么您有這些錯誤,請嘗試在while (!feof($file))之前與這一行進行檢查while (!feof($file))

 if(is_file($csv_file)){ //your code}

此外,在查詢中,您有5個值,而行定義中只有4個值。 並且,為什么你有一個,在那里?

如果您的問題仍然存在,請在此處檢查我的答案,如果您看的話,與您的代碼相似。

您在以下代碼中有語法錯誤。 所以更換

$query = "INSERT INTO cash2011(cashAmount,cashReceivedDate,invoiceNo,monthNum,yearNum) VALUES ('','".$insert_csv['cashAmount']."','".$insert_csv['cashReceivedDate']."','".$insert_csv['customerID']."','".$insert_csv['invoiceNo']."','".$insert_csv['monthNum']."','".$insert_csv['yearNum']."')";

通過

$query = "INSERT INTO cash2011(cashAmount,cashReceivedDate,invoiceNo,monthNum,yearNum) VALUES ('".$insert_csv['cashAmount']."','".$insert_csv['cashReceivedDate']."','".$insert_csv['customerID']."','".$insert_csv['invoiceNo']."','".$insert_csv['monthNum']."','".$insert_csv['yearNum']."')";
