〇简单的方法

$data = array (
    'aaa,bbb,ccc,dddd',
    '123,456,789',
    '"aaa","bbb"');

$fp = fopen('data.csv', 'wb');
foreach($data as $line){
    $val = explode(",",$line);
    fputcsv($fp, $val);
}
fclose($fp);

因此$data数组的每一行都将转到新创建的CSV文件的新行。它只适用于PHP 5及以后的版本。

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);
}

除了上述内容，你可能还需要补充:

header("Content-Transfer-Encoding: UTF-8");

它在处理包含多种语言的文件时非常有用，比如人名或城市。

而不是:

$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00'  AND created<='{$end} 23:59:59'   ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error()); 

while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
    $result.="{$row['email']},";
    $result.="\n";
    echo $result;
}

Use:

$query = "SELECT * FROM customers WHERE created>='{$start} 00:00:00'  AND created<='{$end} 23:59:59'   ORDER BY id";
$select_c = mysql_query($query) or die(mysql_error()); 

while ($row = mysql_fetch_array($select_c, MYSQL_ASSOC))
{
    echo implode(",", $row)."\n";
}

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');
