如何从数组结果创建.csv文件？

Question

我正在使用PHP类实时检查电子邮件的有效性，PHP脚本运行良好：检查电子邮件并将结果打印在同一页上，为每个经过验证的电子邮件创建一个<td>元素。

我的问题是我要验证200,000封电子邮件...脚本的结果是一个庞大的列表，导致我的浏览器停止工作。

是否可以使用结果创建.csv文件，而不是仅将其打印在页面上？ 如果是这样，我该怎么做？

这是我的源代码：

index.php <-这是显示结果的文件。 emailvalid.php <-这是PHP类

我尝试按照@jason的答案给出的说明进行操作，现在可以将生成的电子邮件保存在CSV文件中...但是csv文件包含重复的信息，并且index.php的标题打印为列。

这是我的代码：

在此问题上的任何帮助将不胜感激。 谢谢。

Answer 1

要从数组创建CSV行，请使用$csv_line = implode(',',$array_line); 将其吐出到具有CSV扩展名和中提琴的文件中！

另外，如果我看到了您正在使用的数组的print_r()示例（即是否需要任何循环等），则可以给出更深入的答案。

Answer 2

您可能会拥有最大执行量，以阻止其超时。

 ini_set('max_execution_time', 300); //300 seconds = 5 minutes

此代码将生成csv，您必须根据需要对其进行修改：

<?php
function query_to_csv($db_conn, $query, $filename, $attachment = false, $headers = true) {

    if($attachment) {
        // send response headers to the browser
        header( 'Content-Type: text/csv' );
        header( 'Content-Disposition: attachment;filename='.$filename);
        $fp = fopen('php://output', 'w');
    } else {
        $fp = fopen($filename, 'w');
    }

    $result = mysql_query($query, $db_conn) or die( mysql_error( $db_conn ) );

    if($headers) {
        // output header row (if at least one row exists)
        $row = mysql_fetch_assoc($result);
        if($row) {
            fputcsv($fp, array_keys($row));
            // reset pointer back to beginning
            mysql_data_seek($result, 0);
        }
    }

    while($row = mysql_fetch_assoc($result)) {
        fputcsv($fp, $row);
    }

    fclose($fp);
}

// Using the function
$sql = "SELECT * FROM table";
// $db_conn should be a valid db handle

// output as an attachment
query_to_csv($db_conn, $sql, "test.csv", true);

// output to file system
query_to_csv($db_conn, $sql, "test.csv", false);
?>

Answer 3

这是您需要的：

$fileName = 'emails.csv';

header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header('Content-Description: File Transfer');
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename={$fileName}");
header("Expires: 0");
header("Pragma: public");
