subject 规定邮件的主题。该参数不能包含任何换行字符
message 规定要发送的消息
headers 规定额外的报头，比如 From, Cc 以及 Bcc
parameters 规定 sendmail 程序的额外参数。
碰到的主要问题是乱码问题,刚开始是某些客户端接收邮件时好(比如QQ邮箱,估计带自动那个识别编码)的有些不foxmail、ipad显示乱码,解决方式正确的设置这个mail的headers就行了,下面是我使用的完美的无乱码的例子。
在PHP中配置php.ini文件过程分为两个步骤：
1.先找到你放置所有PHP，Apache，MySQL文件的地方，在PHP文件夹里你可以发现有一个文件：php.ini，打开后，找到mail function地方，将原来的配置代码改为如下（仅对windows系统）：
[mail function] ; For Win32 only. SMTP =mtp_port=25 ; For Win32 only.
sendmail_from = 填上你的电子邮件全称。
此处为以sohu的邮件服务器设置,如果你用163的邮箱,则设置为:
2.在C盘搜索php.ini,选择不是快捷方式的那一个php.ini,应该在C/WINDOWS里面的，打开它，如上面一样修改它,保存,设置完后,记得重启Apache服务器,然后mail()函数就可以用了,示例代码如下:
上面函数不可以带附件了,下面我们升级一下,代码如下:
getEOT(); //生成结尾换行符 $this->getUniq_id(); $this->header = \; $this->attach = \; $this->cc = \; $this->msg = \; } public function getFromaddr() { return $this->fromaddr; } public function setFromaddr($fromaddr) { $this->fromaddr = $fromaddr; } public function getTopic() { return $this->topic; } public function getToaddr() { return $this->toaddr; } public function getCc() { return $this->cc; } public function getContent() { return $this->content; } public function getAttach() { return $this->attach; } public function setTopic($topic) { $this->topic = mb_convert_encoding(trim($topic) , UTF-8, auto); } public function setToaddr($toaddr) { $this->toaddr = trim($toaddr); } public function setCc($cc) { $this->cc = trim($cc); } public function setContent($content) { $this->content = mb_convert_encoding(trim($content) , UTF-8, auto); } public function setAttach($attach) { $this->attach = trim($attach); } public function getDomain() { return $this->domain; } public function setDomain($domain) { $this->domain = $domain; //输入的值为@ } /** 根据系统类型设置换行符 */ private function getEOT() { if (strtoupper(substr(PHP_OS, 0, 3) == WIN)) { $this->eol = "rn"; } elseif (strtoupper(substr(PHP_OS, 0, 3) == MAC)) { $this->eol = "r"; } else { $this->eol = "n"; } } private function getBoundary() { $this->boundary = -- . substr(md5(time() . rand(1000, 2000)) , 0, 16); } private function getUniq_id() { $this->uniqid = md5(microtime() . time() . rand(1, 100)); } private function outputCommonHeader() { $this->header.= From: . $this->fromaddr . $this->eol; //$this->header .= To: .$this->toaddr.$this->eol; //$this->header .= Subject: .$this->topic.$this->eol; $this->header.= Message-ID: uniqid . $this->domain . > . $this->eol; $this->header.= MIME-Version: 1.0 . $this->eol; $this->header.= Reply-To: . $this->fromaddr . $this->eol; $this->header.= Return-Path: . $this->fromaddr . $this->eol; $this->header.= X-Mailer: Xmail System . $this->eol; $this->header.= Content-Disposition: inline . $this->eol; } private function mime_content_type($f) { $temp = trim(exec(file -bi . escapeshellarg($f))); $temp = preg_replace(/s+/, , $temp); $temp = explode( , $temp); return $temp[0]; } //判断文件的mime类型 /** 只带有抄送 */ private function mailWithCC() { $this->header.= Cc: . $this->cc . $this->eol; $this->header.= Content-type: text/html; charset=UTF-8 . $this->eol; $this->header.= Content-Transfer-Encoding: 8bit . $this->eol; $this->msg = $this->content; if (mail($this->toaddr, $this->topic, $this->msg, $this->header)) { return 1; } else { return 0; } } /** $filedir需要是绝对地址 */ private function attachmentToBase64($filedir) { $this->filename = basename($filedir); @$fopen = fopen($filedir, ); $str = fread($fopen, filesize($filedir)); $str = base64_encode($str); $this->filestr = $str; } /** 只带有附件 */ private function mailWithAttach() { $this->attachmentToBase64($this->attach); $this->header.= Content-type: multipart/mixed; boundary=" . str_replace(--, \, $this->boundary) . \" . $this->eol; $this->msg.= $this->eol . $this->boundary . $this->eol; $this->msg.= Content-Type: text/html; charset=utf-8 . $this->eol; $this->msg.= Content-Disposition: inline . $this->eol; $this->msg.= $this->eol . $this->content . $this->eol;

$this->msg.= Content-Transfer-Encoding: base64 . $this->eol; $this->msg.= $this->eol . $this->filestr . $this->eol; $this->msg.= $this->eol . $this->boundary . --; if (mail($this->toaddr, $this->topic, $this->msg, $this->header)) { return 1; } else { return 0; } } /** 带有附件和抄送 */ private function mailAll() { $this->attachmentToBase64($this->attach); $this->header.= Cc: . $this->cc . $this->eol; $this->header.= Content-type: multipart/mixed; boundary=" . str_replace(--, \, $this->boundary) . \" . $this->eol; $this->msg.= $this->eol . $this->boundary . $this->eol; $this->msg.= Content-Type: text/html; charset=utf-8 . $this->eol; $this->msg.= Content-Disposition: inline . $this->eol;

filename=" . $this->filename . \" . $this->eol; $this->msg.= Content-Transfer-Encoding: base64 . $this->eol; $this->msg.= $this->eol . $this->filestr . $this->eol; $this->msg.= $this->eol . $this->boundary . --; if (mail($this->toaddr, $this->topic, $this->msg, $this->header)) { return 1; } else { return 0; } } /** 不带抄送和附件 */ private function mailSimple() { $this->header.= Content-type: text/html; charset=UTF-8 . $this->eol; $this->header.= Content-Transfer-Encoding: 8bit . $this->eol; $this->msg = $this->content; if (mail($this->toaddr, $this->topic, $this->msg, $this->header)) { return 1; } else { return 0; } } public function send() { if (emptyempty($this->attach) && emptyempty($this->cc)) { $this->outputCommonHeader(); return $this->mailSimple(); } else if (emptyempty($this->attach)) { $this->outputCommonHeader(); return $this->mailWithCC(); } else if (emptyempty($this->cc)) { $this->outputCommonHeader(); $this->getBoundary(); //有附件就生成boundary return $this->mailWithAttach(); } else if (!emptyempty($this->toaddr) && !emptyempty($this->topic) && !emptyempty($this->cc) && !emptyempty($this->content) && !emptyempty($this->attach)) { $this->outputCommonHeader();
$this->getBoundary(); //有附件就生成boundary
return $this->mailAll();
}
}
}
?>
示例代码,有些变量需要上下文环境,代码如下:
setToaddr($this->temp[ eceipt_address]);$m->setTopic($this->temp[mail_title]);$m->setContent($this->temp[mail_content]);$m->setFromaddr($_SESSION[user][ ame] . );$m->setDomain(@ . SystemDomain);$m->setCc($this->temp[cc_address]);$m->setAttach(PATH . /temp/ . $this->temp[attachment_file]);$m->send();?>
优点：使用方便就一个简单的函数
缺点：需要php.ini支持该函数，如果某些服务器不支持而又不能改环境那就不行了而且总是不稳定，发的有时能收到有时不能.
