将列添加到CSV文件

可能重复:
  CSVs without quotes not working with fgetcsv

我想首先说我不是PHP开发人员。这是我用PHP编写的第一个应用程序。我还要为没有多少代码显示而道歉。

我有一个CSV文件,我需要在每行中运行,并为每个记录添加一个新列,其中包含我通过函数调用生成的值。我能够弄清楚的大多数PHP是编写函数来获取额外的数据并将文件打开为CSV。

$csvFile = fopen('records.csv');
$csv = fgetcsv($csvFile);

foreach($csv as $line){
    // Create a new code to populate the new column with:
    $linkCode = getUniqueCode();
    // Add the column to the record
    // Save the record back to the csv
}
// Save the CSV back to a file

再次,抱歉缺少更多代码,但我找不到太多资源来处理我正在做的事情。

编辑:这里有更多代码,解析开始结合但尚未完成。我现在遇到的问题是CSV似乎没有被正确解析。我的CSV文件看起来像这样(没有引号):

我的代码如下所示:

<?php
        //require_once "Mail.php";
        //require_once "Mail/mime.php";
        $facebook = '*****';
        $twitter = '*****';
        $band = '*****';
        $album = '******';
        $paypal = '******';
        $download = '******';

        function makeConnection(){
                $host=$_ENV{'DATABASE_SERVER'};
                $username="*******";
                $password="*********";
                $db_name="**********";
                $con = mysql_connect("$host", "$username", "$password")or die(mysql_error());
                mysql_select_db("$db_name")or die(mysql_error());
                return $con;
        }

        function makeCode($email, $name){
                $codeused = true;
                do{
                        $code = substr(microtime().'_'.$GLOBAL['album'],2,6);
                        $escapeCode = mysql_escape_string($code);
                        $query = mysql_query("SELECT * FROM downloads WHERE code='$code'")or die(mysql_error());
                        if(!mysql_num_rows($query))$codeused = false;
                        else $codeused = true;
                }while($codeused);

                $email = mysql_escape_string($email);
                $name = mysql_escape_string($name);
                $download = mysql_escape_string($GLOBALS['download']);

                $query = mysql_query("INSERT INTO downloads(email,name,code,download) VALUES('$email','$name','$code','$download')")or die(mysql_error());

                return 'http://********'.$code;
        }

        $conn = makeConnection();

        if(($csvFile = fopen('emails.csv','r')) !== false && ($resultCsv = fopen('result.csv','w')) !== false){
                while (($data = fgetcsv($csvFile)) !== false){
                        $data[] = makeCode($data[1],$data[0]);
                        echo $data;
                        fputcsv($resultCsv, $data);
                }
                fclose($csvFile);
                fclose($resultCsv);
        }
?>

这样的事情:

ini_set('auto_detect_line_endings',TRUE); // Fixes problem with Mac Excel    
if (($csvFile = fopen("records.csv", "r")) !== false && ($resultCsv = fopen('result.csv', 'w')) !== false) {
    while (($data = fgetcsv($csvFile)) !== false) {
        $data[] = getUniqueCode();
        fputcsv($resultCsv, $data);
    }
    fclose($csvFile);
    fclose($resultCsv);
}
