php邮件程序未发送邮件。代码中可能有错误吗？

这是我想通过php发送电子邮件的代码。
这是我的代码，但邮件功能无法正常工作。它显示的错误是：Mailer error无法实例化邮件函数

    <?php
                require_once('PHPMailer/class.phpmailer.php');

这是我的代码，但邮件功能无法正常工作。它显示的错误是：Mailer error无法实例化邮件功能。

检查sendmail是否已启用，主要是当您的服务器由其他公司提供时

    <?php
                require_once('PHPMailer/class.phpmailer.php');

                    $mmobile= $_REQUEST['mmobile'];

                    $gemail= str_replace("atsymbol","@",$memail);

上的PHPMailer帮助文档帮助我走上正确的道路

我发现

php.ini

没有定义

sendmail\u路径

，所以我添加了

sendmail\u路径=/usr/sbin/sendmail-t-I
1。您需要确保您的发件人地址是该服务器上设置的有效电子邮件帐户

2.确保还包括phpmailer附带的smtp类：

// for mailing
require("phpmailer/class.phpmailer.php");
require("phpmailer/class.smtp.php");
require  'phpmailer/PHPMailerAutoload.php'; 

我希望这有帮助
我已经有一段时间没有看到ereg的行动了。5.3中没有折旧吗？
