PHPMailer::msgHTML()
Create a message body from an HTML string. Automatically inlines images and creates a plain-text version by converting the HTML, overwriting any existing values in Body and AltBody. Do not source $message content from user input! $basedir is prepended when handling relative URLs, e.g. <img src="/images/a.png"> and must not be empty will look for an image file in $basedir/images/a.png and convert it to inline. If you don't provide a $basedir, relative paths will be left untouched (and thus probably break in email) Converts data-uri images into embedded attachments. If you don't want to apply these transformations to your HTML, just set Body and AltBody directly.

Использование
$PHPMailer = new PHPMailer(); $PHPMailer->msgHTML( $message, $basedir, $advanced );
- $message(строка) (обязательный)
- HTML message string
- $basedir(строка)
- Absolute path to a base directory to prepend to relative paths to images
По умолчанию: '' - $advanced(true|false|callable)
- Whether to use the internal HTML to text converter or your own custom converter
