[php]php curl smtp发送邮件_PHP教程

公司的云平台把fsockopen关掉了,如果要使用smtp外网的邮箱来发送邮件的话 只能试试使用curl来进行了
先google了一下,发现很多问相关问题的但没有相关的解答,在phpclasses里也没有找到相关的类于是自己边看stmp的相关协议边开始尝试curl
SMTP协议
这个在网上可以找到多相关的例子,可以自己实验一下使用telnet去连接mail服务器
 
$ telnet 邮箱SMTP服务地址 25
Trying 邮箱服务IP地址...

Escape character is '^]'.

php测试代码:
 
 1  2 header("content-type:text/html;charset=utf-8");
 3 $smtp = array(
 4     "url"      => "邮箱SMTP服务器地址",
 5     "port"     => "邮箱SMTP服务器端口", // 一般为25
 6     "username" => "用户名",
 7     "password" => "密码",
 8     "from"     => "发件地址",
 9     "to"       => "收件地址",
10     "subject"  => "测试一下标题",
11     "body"     => "测试一下内容"
12 );
13
14 $CRLF = "\r\n";
15 $test = "";
16 $curl = curl_init();
17
18 curl_setopt($curl, CURLOPT_URL, $smtp['url']);
19 curl_setopt($curl, CURLOPT_PORT, $smtp['port']);
20 curl_setopt($curl, CURLOPT_TIMEOUT,10);
21
22 function inlineCode($str){
23         $str = trim($str);
24         return $str?'=?UTF-8?B?'.base64_encode($str).'?= ':'';
25 }
26
27 function buildHeader($headers){
28     $ret = '';
29     foreach($headers as $k=>$v){
30         $ret.=$k.': '.$v."\n";
31     }
32     return $ret;
33 }
34
35 //
36 $header = array(
37     'Return-path'=>'',
38     'Date'=>date('r'),
39     'From'=> '',
40     'MIME-Version'=>'1.0',
41     'Subject'=>inlineCode($smtp['subject']),
42     'To'=>$smtp['to'],
43     'Content-Type'=>'text/html; charset=UTF-8; format=flowed',
44     'Content-Transfer-Encoding'=>'base64'
45 );
46 $data = buildHeader($header).$CRLF.chunk_split(base64_encode($smtp['body']));
47
48
49 $content  = "EHLO ".$smtp["url"].$CRLF; // 先得hello一下
50 $content .= "AUTH LOGIN".$CRLF.base64_encode($smtp["username"]).$CRLF.base64_encode($smtp["password"]).$CRLF; // 验证登陆
51 $content .= "MAIL FROM:".$smtp["from"].$CRLF; // 发件地址
52 $content .= "RCPT TO:".$smtp["to"].$CRLF;  // 收件地址
53 $content .= "DATA".$CRLF.$data.$CRLF.".".$CRLF; // 发送内容
54 $content .= "QUIT".$CRLF; // 退出
55
56 curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);    // curl接收返回数据
57 curl_setopt($curl, CURLOPT_CUSTOMREQUEST, $content);
58 $test = curl_exec($curl);
59 var_dump($test);
60 echo "
\r\n";
61 var_dump($content);
62
63 // 结束
64 curl_close($curl);
 
以上只是测试的php
包测试+修改花了近6个小时让产品的代码兼容了fsockopen和curl
 
以后有空写个兼容fsockopen和curl简单发送邮件的smtp类
think in coding
