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:
<?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

function __construct() {
$this->getEOT(); //生成结尾换行符
$this->getUniq_id();
$this->header = '';
$this->attach = '';
$this->cc = '';

}
?>
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.
