如何写在CSV文件使用PHP脚本?其实我也在找这个。这在PHP中很简单。 Fputs(处理程序，内容)-这个函数为我有效地工作。首先，您需要使用fopen($CSVFileName， ' wb ')打开需要写入内容的文件。

$CSVFileName = “test.csv”;
$fp = fopen($CSVFileName, ‘wb’);

//Multiple iterations to append the data using function fputs()
foreach ($csv_post as $temp)
{
    $line = “”;
    $line .= “Content 1″ . $comma . “$temp” . $comma . “Content 2″ . $comma . “16/10/2012″.$comma;
    $line .= “\n”;
    fputs($fp, $line);
}

您可以使用fputcsv函数简单地将数据写入CSV。让我们看看下面的例子。将列表数组写入CSV文件

$list[] = array("Cars", "Planes", "Ships");
$list[] = array("Car's2", "Planes2", "Ships2");
//define headers for CSV 
header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=file_name.csv');
//write data into CSV
$fp = fopen('php://output', 'wb');
//convert data to UTF-8 
fprintf($fp, chr(0xEF).chr(0xBB).chr(0xBF));
foreach ($list as $line) {
    fputcsv($fp, $line);
}
fclose($fp);

首先将data作为String，以逗号作为分隔符(用“，”分隔)。就像这样

$CSV_string="No,Date,Email,Sender Name,Sender Email \n"; //making string, So "\n" is used for newLine

$rand = rand(1,50); //Make a random int number between 1 to 50.
$file ="export/export".$rand.".csv"; //For avoiding cache in the client and on the server 
                                     //side it is recommended that the file name be different.

file_put_contents($file,$CSV_string);

/* Or try this code if $CSV_string is an array
    fh =fopen($file, 'w');
    fputcsv($fh , $CSV_string , ","  , "\n" ); // "," is delimiter // "\n" is new line.
    fclose($fh);
*/

下面是@Andrew发布的php.net函数的改进版本。

function download_csv_results($results, $name = NULL)
{
    if( ! $name)
    {
        $name = md5(uniqid() . microtime(TRUE) . mt_rand()). '.csv';
    }

    header('Content-Type: text/csv');
    header('Content-Disposition: attachment; filename='. $name);
    header('Pragma: no-cache');
    header("Expires: 0");

    $outstream = fopen("php://output", "wb");

    foreach($results as $result)
    {
        fputcsv($outstream, $result);
    }

    fclose($outstream);
}

它真的很容易使用，并且与MySQL(i)/PDO结果集一起工作。

download_csv_results($results, 'your_name_here.csv');

如果完成了页面，请记住在调用此函数后退出()。

要让它以CSV格式发送，并给出文件名，请使用header():

http://us2.php.net/header

header('Content-type: text/csv');
header('Content-disposition: attachment; filename="myfile.csv"');

至于创建CSV本身，您只需要遍历结果集，格式化输出并发送它，就像处理任何其他内容一样。

    $fileName = '/tmp/notificationresponselogs_' . date('d-m-Y-g-i-h') . '.csv';
