send csv attachment without upload-CodePudding

I found a lot of example how to create csv and send it as attachment. All of these examples upload the file on the server. Is there a way to send the csv created without upload it so to be sent directly as attachment?

CodePudding user response：

you can try to use addStringAttachment

see: https://phpmailer.github.io/PHPMailer/classes/PHPMailer-PHPMailer-PHPMailer.html#method_addStringAttachment

Of course there is! There are many ways of making CSV files, but a basic one is very simple:

$data = [
    ['id', 'name', 'colour'],
    [1, 'Fred', 'blue'],
    [2, 'Jane', 'orange'],
    [3, 'Hassan', 'purple'],
];
$csv = fopen('file.csv', 'wb');
foreach($data as $line) {
    fputcsv($csv, $line);
}
fclose($csv);

//then later on, to send it with PHPMailer
$mail->addAttachment('file.csv');

Of course the data can come from anywhere - a database, a calculation, a remote web service, or whatever.

You could use output buffering to capture the CSV string output by fputcsv and pass that directly to addStringAttachment, which would mean you don't even need to write the file to disk before sending.
