本文介绍下,一个用于email邮件发送的类,可以使用smtp与mail函数二种方式发送邮件,有需要的朋友参考下。
php实现的邮件发送类,二种方式: smtp方式与mail函数方式。 代码: <?php /** * 邮件发送类 * by bbs.it-home.org */ Class sendmail{ public $smtp_host; public $smtp_port = 25; public $smtp_user; public $smtp_password; public $from_name; public $SendFromMail; public $mail_to; public $subject; public $message; public $headers = ''; public $ContentType = 'html'; public $charset = 'windows-1251'; public $smtp_debug = true; public $socket; public $error; public $SendMailVia = 'smtp'; public function __construct() { if($this->SendFromMail == ''){ $this->SendFromMail = $this->smtp_user; } } public function Send($mail_to = '', $subject = '', $message = '') { if($mail_to!=''){$this->mail_to = stripslashes($mail_to);} if($subject!=''){$this->subject = stripslashes($subject);} if($message!=''){$this->message = $message;} $meilsArr = array_filter($this->GetMailAndNameArr()); if(trim($this->mail_to)==''){$this->error = 'Enter the recipient address'; } if($meilsArr == array()){$this->error = 'Please enter a valid recipient address'; } foreach ($meilsArr as $val) { $validEmail = $this->validEmail($val[2]); if($validEmail) { if($this->SendMailVia=='smtp'){ return $this->SMTPsend($mail_to = $val[2], $name_to = $val[1]); } else{ return $this->MAILsend($mail_to = $val[2], $name_to = $val[1]); } } } } public function MAILsend($mail_to, $name_to) { if($this->ContentType=="text"){ $header="Content-Type: text/plain; charset=".$this->charset.""; } else{ $header="Return-Path: ".$this->smtp_user."\n".
