How to use it

$TheAttachments = array('CurriculumReviewCycle.pdf'=>file_get_contents('/var/www/html/CurriculumReviewCycle.pdf'));

// SendMail($ServerName, $Port, $Username, $Password, $ToEmail, $FromEmail, $Subject, $Body, $Attachments='' )

SendMail('smtp.gmail.com', 25, 'franklinc@fromdomain', 'Password', 'cfranklin@todomain', 'franklinc@fromdomain', 'Attach - Test - subject', 'What up dog! - the body', $TheAttachments);
