mail函数,发送邮件
语法: mail(to,subject,message,headers,parameters)
to 规定邮件的接收者
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 =smtp.sohu.com 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:smtp.163.com
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:
<?php // 当发送 HTML 电子邮件时,请始终设置 content-type $headers = "MIME-Version: 1.0" . "rn"; $headers.= "Content-type:text/html; charset=utf-8"; mail($to, $subject, $message, $headers); ?>
上面函数不可以带附件了,下面我们升级一下,代码如下:
<?php class Mail { private $topic; private $toaddr; private $fromaddr; private $cc; private $content; private $attach; private $header; private $domain; //邮箱域 private $msg; private $filename; private $filemime; private $filestr; private $boundary; private $uniqid; private $eol; //每行末尾所加的换行符类型 function __construct() { $this->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'@domain.com' } /* * 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: <' . $this->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, 'r'); $str = fread($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.= $this->boundary . $this->eol; $this->msg.= 'Content-Type: ' . $this->mime_content_type($this->attach) . $this->eol; $this->msg.= 'Content-Disposition: attachment; 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; } } /* * 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; $this->msg.= $this->eol . $this->content . $this->eol; $this->msg.= $this->boundary . $this->eol; $this->msg.= 'Content-Type: ' . $this->mime_content_type($this->attach) . $this->eol; $this->msg.= 'Content-Disposition: attachment; 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:
<?php $m = new Mail(); $m->setToaddr($this->temp['receipt_address']); $m->setTopic($this->temp['mail_title']); $m->setContent($this->temp['mail_content']); $m->setFromaddr($_SESSION['user']['name'] . ' <' . $_SESSION['user']['name'] . '@' . SystemDomain . '>'); $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.
