PHPMailer::setWordWrap() │ public │ WP 1.0

Apply word wrapping to the message body. Wraps the message body to the number of chars set in the WordWrap property. You should only do this to plain-text bodies as wrapping HTML tags may break them. This is called automatically by createBody(), so you don't need to call it yourself.

Method of the class: PHPMailer{}

No Hooks.

Return

null. Nothing (null).

Usage

$PHPMailer = new PHPMailer();
$PHPMailer->setWordWrap();
