PHP 如何自动发送邮件?

2016-11-25 15:34 399 查看
  php自带mail方法,不过只能在linux下直接使用,windows下要配置smtp服务器,有点麻烦。

  可以用一些现成的类来实现,比如很有名的phpmailer,功能很强大,代码也多,这里使用个相对简单的。



1 <?php
2 class smtp
3 {
4     /* Public Variables */
5     var $smtp_port;
6     var $time_out;
7     var $host_name;
8     var $log_file;
9     var $relay_host;
10     var $debug;
11     var $auth;
12     var $user;
13     var $pass;
14
15     /* Private Variables */
16     var $sock;
17
18     /* Constractor */
19     function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass)
20     {
21         $this->debug = FALSE;
22         $this->smtp_port = $smtp_port;
23         $this->relay_host = $relay_host;
24         $this->time_out = 30; //is used in fsockopen()
25         $this->auth = $auth;//auth
26         $this->user = $user;
27         $this->pass = $pass;

  这是已经封装好的类,使用方式如下:



1 <?php
2   // 引入发送邮件类
3   require("smtp.php");
4   // 使用qq邮箱服务器
5   $smtpserver = "smtp.qq.com";
6   // qq邮箱服务器端口
7   $smtpserverport = 25;
8   // 你的qq服务器邮箱账号
9   $smtpusermail = "xxxxxxx@qq.com";
10   // 收件人邮箱
11   $smtpemailto = "bigbigsunrise@foxmail.com";
12   // 你的邮箱账号(去掉@qq.com) SMTP服务器的用户帐号
13   $smtpuser = "xxxxxxx";
14   // 你的邮箱密码 SMTP服务器的用户密码
15   $smtppass = "xxxxxxx";
16
17   // 邮件主题
18   $mailsubject = "测试邮件发送";
19   // 邮件内容
20   $mailbody = 'test';
21   // 邮件格式(HTML/TXT,TXT为文本邮件
22   $mailtype = "TXT";
23   // 这里面的一个true是表示使用身份验证,否则不使用身份验证.
24   $smtp = new smtp($smtpserver, $smtpserverport, true, $smtpuser, $smtppass);
25   // 是否显示发送的调试信息
26   $smtp->debug = TRUE;
27   //发送邮件
28   $smtp->sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
29 ?>


  将index.php里的一些参数配置好,然后在浏览器打开index.php,就能自动发送邮件了。

 

如何批量发送邮件?

用户脚本 
  可以直接写个运行在index.php上的用户脚本,定时刷新。

ajax
  写个index.html页面,里面发送ajax请求。

  $.ajax():

   $.post():

  如果index.php里要用post或者get发送的参数(键值对),可以用$_POST['content']或者$_GET['content']实现。

  这里有个很奇怪的地方,如果用post方法,要实现多次发送,必须要带key/value的键值对,而内容则无要求;而如果要用get方法,不仅要带key/value键值对,而且每次需带不同的,如下:

  我觉得应该是我对get和post区别不了解的原因。

  ps:原来我想直接在index.php里写个for循环,不知道为何不行。

 

get和post
