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
-
- $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;

示例代码,有些变量需要上下文环境,代码如下:
- $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. |
