Create CSV files and add data depending on condition php - php

Question

I have an array of results and I want to create csv file for it. but if the result is valid I want to add the email in the valid csv file and if it is invalid then in the invalid csv file. but I am unable to do this. it adds all the emails to clean csv file and the invalid csv is empty. any suggestions
the results are looks like this:
Array
(
[0] => Array
(
[email] => tamas.szabo#millionverifier.com
[result] => valid
)
[1] => Array
(
[email] => support#millionverifier.com
[result] => valid
)
)
Here is my condition
// 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);
}

May be you want line-by-line separation?
// 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
}
