利用php中mail函数发送带有附件的邮件

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:

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;
    }

            $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['receipt_address']);
$m->setTopic($this->temp['mail_title']);
$m->setContent($this->temp['mail_content']);
$m->setFromaddr($_SESSION['user']['name'] . ' ');
$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.
