phpmailerHow can I configure PHPMailer to ignore TLS certificate errors?

PHPMailer can be configured to ignore TLS certificate errors by setting the SMTPOptions property to an array containing the ssl key and the verify_peer and verify_peer_name keys set to false as shown in the following example:

$mail->SMTPOptions = array(
    'ssl' => array(
        'verify_peer' => false,
        'verify_peer_name' => false
    )
);

The above code will configure PHPMailer to ignore TLS certificate errors.

Code explanation

1. $mail->SMTPOptions - The property used to configure PHPMailer to ignore TLS certificate errors.
2. ssl - The key inside the SMTPOptions array that contains the settings for ignoring TLS certificate errors.
3. verify_peer - The key inside the ssl array that must be set to false to ignore TLS certificate errors.
4. verify_peer_name - The key inside the ssl array that must be set to false to ignore TLS certificate errors.
