用php自动发邮件的简单实现
如何自动发送邮件？
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。

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 = "[email protected]"; 10 // 收件人邮箱 11 $smtpemailto = "[email protected]"; 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():
for(var i = 0; i < 3; i++) {
$.ajax({
type: 'POST',
url: 'http://localhost/index.php',
// dataType: '',
async: true, // 异步，一起发送 如果false 则一个一个来
data: {content:'test'},
success: function(msg) {
// alert(msg);
}
});
}
$.post():
for(var i = 0; i < 3; i++) {
$.post(
'http://localhost/index.php',
{
'content': 'test'
},
function(data, status) {
// console.log(data);
}
);
}
如果index.php里要用post或者get发送的参数（键值对），可以用$_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:
var a = ['test1', 'test2', 'test3', 'test4', 'test5'];
for(var i = 0; i < 3; i++) {
$.get(
'http://localhost/index.php',
{
// 'content': 'test' // 不行
'content': a[i]
},
function(data, status) {
// console.log(data);
}
);
}
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
demo：
ajax部分：
$.get(
'http://127.0.0.1/ajax/index.php',
function(data, status) {
console.log(data);
}
);
php部分：
<?php
function randomFloat() {
return mt_rand() / mt_getrandmax();
}
echo randomFloat();
?>
