PHP演示如何发送邮件给某个邮箱

首先，建立一个index.htML文件，代码如下：

html>
    head>
    tITle>
    Simple Send Mail /title>
    /head>
    body>
    h1>
    mail Form/h1>
    form name="form1" method="post" action="mail.php">
    table>
    tr>
    td>
    b>
    To/b>
    /td>
    td>
    input tyPE="text" name="mailto" size="35">
    /td>
    /tr>
    tr>
    td>
    b>
    Subject/b>
    /td>
    td>
    input type="text" name="mailsubject" size="35">
    /td>
    /tr>
    tr>
    td>
    b>
    Message/b>
    /td>
    td>
    textarea name="mailbody" cols="50" rows="7">
    /textarea>
    /td>
    /tr>
    tr>
    td colspan="2">
    input type="submit" name="Submit" value="Send">
    /td>
    /tr>
    /table>
    /form>
    /body>
    /html>
    

然后新建一个“mail.php”文档把传输的文档进行发送

?php $stm="邮件内容";
     require("smtp.php");
     ########################################## $smtpserver = "smtp.QQ.COM";
    //SMTP服务器 $smtpserverport = "465";
    //SMTP服务器端口 $smtpusermail = "XXX@qq.com";
    //SMTP服务器的用户邮箱 $smtpemailto = "AAA@qq.com";
    //发送给谁 $smtpuser = "XXX@qq.com";
    //SMTP服务器的用户帐号 $smtppass = "666";
    //SMTP服务器的用户密码 $mailsubject = "666 ";
    //邮件主题 $mailbody = $stm;
    //邮件内容 $mailtype = "HTML";
    //邮件格式（HTML/TXT）,TXT为文本邮件 ########################################## $smtp = new smtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);
    //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. $smtp->
    debug = TRUE;
    //是否显示发送的调试信息 $smtp->
    sendmail($smtpemailto, $smtpusermail, $mailsubject, $mailbody, $mailtype);
     echo "script>
    alert('邮件发送成功');
    parent.document.ADDUser.cheheh.click();
    /script>
    ";
     exit;
 }
     ?>
    

最后编写一个邮件类“smtp.php”

?php class smtp {
     /* Public VARiables */ var $smtp_port;
     var $time_out;
     var $host_name;
     var $LOG_file;
     var $relay_host;
     var $debug;
     var $auth;
     var $user;
     var $pass;
     /* PRivate Variables */ var $sock;
 /* Constractor */ function smtp($relay_host = "", $smtp_port = 25,$auth = false,$user,$pass) {
     $this->
    debug = FALSE;
     $this->
    smtp_port = $smtp_port;
     $this->
    relay_host = $relay_host;
     $this->
    time_out = 30;
     //is used in fsockopen() $this->
    auth = $auth;
    //auth $this->
    user = $user;
     $this->
    pass = $pass;
     $this->
    host_name = "localhost";
     //is used in HELO command $this->
    log_file = "";
     $this->
    sock = FALSE;
 }
