phpmailer发邮件常见的一些问题总结及使用案例


PHPMailer邮件类使用错误分析

一,没有定义发送邮箱$mail->From或格式不正确,错误提示:Language string failed to load: recipients_failed [email protected],注意,这个配置一定要正确,而且是正确的邮箱

二,没有定义邮件服务主机$mail->Host或连接失败,错误提示:Language string failed to load: connect_host

三,没有定义发送邮箱$mail->AddAddress或邮箱格式不正确,错误提示:Language string failed to load: provide_address

四,没有定义邮箱发送用户名$mail->Username,错误提示:Language string failed to load: connect_host

五,没有定义邮箱发送密码$mail->Password,错误提示:Language string failed to load: connect_host,这类错误非常明显,一般都是邮箱服务器配置不正确不能边接。

六,邮件正文编码,如果发送HTML邮件,需要定义正确的编码格式和字符,发送GBK邮件如下:
$mail->IsHTML ( true ); 是否支持HTML邮件
$mail->CharSet = "GB2312"; 字符设置
$mail->Encoding = "base64"; 编码方式
配置后可直接发送HTML邮件,如下:

七,学会正确使用错误提示$mail->ErrorInfo查看邮件错误,可直接查找问题。

使用PHPMailer邮件类发送邮件使用非常简单,基本配置如上所示,在使用过程中正确了解错误提示,并及时了解错误原因,对于正确使用PHPMailer邮件类来说非常重要。

这几天做mail群发,碰到不少问题。一些常见的错误网上很多但没有答案,靠自己不断的尝试终于OK了~这里把几个常见的问题列出来做为工作笔记!
     要做发送邮件功能,首先要明白邮件收发的原理,引用网友一段话比较容易懂:

  1. 在Internet上将一段文本信息从一台计算机传送到另一台计算机上,可通过两种协议来完成,即SMTP(Simple Mail Transfer Protocol,简单邮件传输协议)和POP3(Post Office Protocol,邮局协议3)。SMTP是Internet协议集中的邮件标准。在Internet上能够接收电子邮件的服务器都有SMTP。电子邮件在发送前,发件方的SMTP服务器与接收方的SMTP服务器联系,确认接收方准备好了,则开始邮件传递;若没有准备好,发送服务器便会等待,并在一段时间后继续与接收方邮件服务器联系。这种方式在Internet上称为“存储——转发”方式。POP3可允许E-mail客户向某一SMTP服务器发送电子邮件,另外,也可以接收来自SMTP服务器的电子邮件。换句话说,电子邮件在客户PC机与服务提供商之间的传递是通过P0P3来完成的,而电子邮件在 Internet上的传递则是通过SMTP来实现。

如果觉得不够清楚的话,则引用网上的一张图来解释吧:

有关phpmailer的介绍可以参考官网:http://phpmailer.codeworxtech.com/

常见异常:

1.SMTP Error: Could not authenticate.

   这个是因为smtp验证没通过,就是smtp server 的用户名和密码不正确了

    $mail->Username    = "[email protected]";     // SMTP server username   
    t;Password    = "******";     

$mail->Username = "[email protected]"; // SMTP server username $mail->Password = "******";

2.Could not execute: /usr/sbin/sendmail

    这是因为

    $mail->IsSendmail();  // tell the class to use Sendmail   

$mail->IsSendmail(); // tell the class to use Sendmail

   去掉上面的代码就ok了!(PHP同理)

3.关于phpmailer发送邮件产生中文乱码问题

环境一:在普通环境,即标题内容等含中文的内容是在脚本中加上去的,或从文本中获取的,只需要进行如下操作(网上有很多):
   修改class.phpmailer.php中的EncodeHeader函数,改为:

    public function EncodeHeader($str, $position = 'text', $pl = 0) {   
       $x = 0;   
       if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";}   

public function EncodeHeader($str, $position = 'text', $pl = 0) { $x = 0; if ($pl){return "=?".$this->CharSet."?B?".base64_encode($str)."?=";}

再改下使用这个函数的一段:

    if($this->Mailer != 'mail') {   
          $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1));   
         }  

if($this->Mailer != 'mail') { $result .= $this->HeaderLine('Subject', $this->EncodeHeader($this->SecureHeader($this->Subject),'text',1)); }

当然编码设置也不能少了:
    $mail->CharSet="utf-8";   
           $mail->Encoding = "base64";  

$mail->CharSet="utf-8"; $mail->Encoding = "base64";

环境二:从excel中提取内容然后再发送excel中的内容给用户,这个折腾了我好久。最终找到解决办法了。最关键的地方是:excel中的编码是html格式的unicode,所以得使用下面这个函数将其转化为utf8,这个帖子的最后回复的人帮了我,谢谢他!帖子地址是:http://www.phpchina.com/bbs/viewthread.php?tid=111554

    private function uc2html($str)   
       {   
        $ret = '';   
        for( $i=0; $i

下面贴段测试代码:

IsSMTP();                           // tell the class to use SMTP   
    $mail->SMTPAuth    = true;                  // enable SMTP authentication   
    $mail->Port        = 25;                // set the SMTP server port   
    $mail->Host        = "smtp.xxxx.com"; // SMTP server   
    $mail->Username    = "[email protected]";     // SMTP server username   
    $mail->Password    = "xxxx";            // SMTP server password   
  
    $mail->IsSendmail();  // tell the class to use Sendmail   
  
    $mail->AddReplyTo("[email protected]","xxxx");   
  
    $mail->From        = "[email protected]";   
    $mail->FromName    = "DJB";   
  
    $to = "[email protected]";   
  
    $mail->AddAddress($to);   
  
    $mail->Subject   = "First PHPMailer Message";   
  
    $mail->AltBody     = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test   
    $mail->WordWrap    = 80; // set word wrap   
  
    $mail->MsgHTML($body);   
  
    $mail->IsHTML(true); // send as HTML   
  
    $mail->Send();   
    echo 'Message has been sent.';   
} catch (phpmailerException $e) {   
    echo $e->errorMessage();   
}   
?>
