}上面是函数的源码，使用方法：
$TheAttachments = array(
'CurriculumReviewCycle.pdf' => file_get_contents('/var/www/html/CurriculumReviewCycle.pdf')
);
// SendMail($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);全文代码完整来自:https://www.nomadcf.com/scripting/php-sendemailsockets-withattachments
