根据条件php创建CSV文件并添加数据

Question

我有一个结果数组，我想为此创建一个csv文件。但是如果结果有效，我想在有效的csv文件中添加电子邮件，如果无效，则在无效的csv文件中添加电子邮件。但是我做不到。它将所有电子邮件添加到干净的csv文件中，并且无效的csv为空。任何建议

结果看起来像这样：

Array
(
    [0] => Array
        (
            [email] => [email protected]
            [result] => valid
        )

    [1] => Array
        (
            [email] => [email protected]
            [result] => valid
        )

)

这是我的病情

// creating dirty and clean file
$clean_emails = fopen(UPLOAD_DIRECTORY . '/clean/' . $file_name_new . '.' . $extension, 'w');
$dirty_emails = fopen(UPLOAD_DIRECTORY . '/dirty/' . $file_name_new . '.' . $extension, 'w');

// adding headers to them
fputcsv($clean_emails, $headers);
fputcsv($dirty_emails, $headers);            

if ($results[$i]['result'] === 'valid') {

    // adding clean emails to csv
    foreach ($results as $row) {
    fputcsv($clean_emails, $row);
    }
    fclose($clean_emails);

} elseif ($results[$i]['result'] === 'invalid') {

    // adding dirty emails to csv
    foreach ($results as $row) {
    fputcsv($dirty_emails, $row);
    }
    fclose($dirty_emails);

} else {

    // if there are not any dirty or clean emails add them unknown to csv
    $unknown_emails = fopen(UPLOAD_DIRECTORY . '/unknown/' . $file_name_new . '.' . $extension, 'w');
    fputcsv($unknown_emails, $row);
    fclose($unknown_emails);

}

您可能要逐行分隔吗？

// creating dirty and clean file
$clean_emails = fopen(UPLOAD_DIRECTORY . '/clean/' . $file_name_new . '.' . $extension, 'w');
$dirty_emails = fopen(UPLOAD_DIRECTORY . '/dirty/' . $file_name_new . '.' . $extension, 'w');
$unknown_emails = null; // No file yet

// adding headers to them
fputcsv($clean_emails, $headers);
fputcsv($dirty_emails, $headers);            

foreach ($results as $row) { // Scan each row
    if ($row['result'] === 'valid') {
        fputcsv($clean_emails, $row);
    } elseif ($row['result'] === 'invalid') {
        fputcsv($dirty_emails, $row);
    } else {  // found something else
        if (!isset($unknown_emails)) { // Open file if it was not
            $unknown_emails = fopen(UPLOAD_DIRECTORY . '/unknown/' . $file_name_new . '.' . $extension, 'w');
            fputcsv($unknown_emails, $headers); // Add headers ?
        }
        fputcsv($unknown_emails, $row);
    }
} // end loop
fclose($clean_emails);
fclose($dirty_emails);
if (isset($unknown_emails)) {
    fclose($unknown_emails); // Close 'unknown' if it was opened
}
