How to disable log after mail send in php mailer

By default, the PHPMailer library logs various events, including the sending of emails, to a log file. If you want to disable this logging, you can set the SMTPDebug option to 0 or false when creating the PHPMailer object.

Here's an example:

$mail = new PHPMailer(true);
$mail->SMTPDebug = 0; // or false

This will disable all SMTP debugging output, including the log file.

Alternatively, you can set the Debugoutput option to null to disable the log file:

$mail = new PHPMailer(true);
$mail->Debugoutput = null;

You can also set the Log option to false to disable the log file:

$mail = new PHPMailer(true);
$mail->Log = false;

Note that setting SMTPDebug to 0 or false will also disable the SMTP debugging output, which can be useful for troubleshooting issues with your email server.

If you want to keep the SMTP debugging output but disable the log file, you can set SMTPDebug to a value other than 0 or false, such as 2 or 3. This will provide more detailed information about the SMTP connection and authentication process.

For example:

$mail = new PHPMailer(true);
$mail->SMTPDebug = 2; // or 3

This will provide more detailed SMTP debugging output, but the log file will still be generated.
