Save PHPMailer debug to database not working

Question

I have a php script that sends emails using PHPMailer see below:

$mail = new PHPMailer(true);
try {
    $debug = NULL;
    $mail->Debugoutput = function($str, $level) {
        $GLOBALS['debug'] .= "$level: $str\n";
    };
    $mail->isSMTP();
    $mail->Host = 'xxxxxxx';
    $mail->SMTPDebug = 2;
    $mail->SMTPAuth = true;
    $mail->Username = 'xxxxxx';
    $mail->Password = 'xxxxxx';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;
    $mail->setFrom('[email protected]', 'xxx');
    $mail->addAddress('[email protected]');
    $mail->isHTML(true);
    $mail->Subject = 'xx';
    $email_content = '<p>test</p>';
    $mail->Body = $email_content;
    $mail->send();
    fncSaveLog($debug);
} catch (Exception $e) {
    fncSaveLog($mail->ErrorInfo);
}

the fncSaveLog is a function that saves debug info to database but I see always NULL for debug in my DB, it seems the output is never caught. Any idea how to fix this please?

Thanks.

Your setting NULL to save into the db. Try the below instead:

$mail = new PHPMailer(true);
try {

    $mail->Debugoutput = function($str, $level) {
        $GLOBALS['debug'] .= "$level: $str\n";
    };
    $mail->isSMTP();
    $mail->Host = 'xxxxxxx';
    $mail->SMTPDebug = 2;
    $mail->SMTPAuth = true;
    $mail->Username = 'xxxxxx';
    $mail->Password = 'xxxxxx';
    $mail->SMTPSecure = 'tls';
    $mail->Port = 587;
    $mail->setFrom('[email protected]', 'xxx');
    $mail->addAddress('[email protected]');
    $mail->isHTML(true);
    $mail->Subject = 'xx';
    $email_content = '<p>test</p>';
    $mail->Body = $email_content;
    $mail->send();
    $debug = $GLOBALS['debug'];
    fncSaveLog($debug);
} catch (Exception $e) {
    fncSaveLog($mail->ErrorInfo);
}
