  在现如今,作为PHP网站开发程序员需要接触到各种程序接口,比如网站修改密码使用smtp类轻松的发送电子邮件,首先smtp类发送邮件的方法其实很简单,也很稳定,类是别人已经写好的了,你只需要调用就行了。几行简单的配置就能发邮件,下面我们一起来看一下吧。

  email.class.php文件

  发送邮箱的php文件


  require_once"email.class.php";


  //********************配置信息********************************


  $smtpserver="smtp.XX.com";//SMTP服务器


  $smtpserverport=25;//SMTP服务器端口


  $smtpusermail="new2018oh@XX.com";//SMTP服务器的用户邮箱


  $smtpemailto=$_POST['toemail'];//发送给谁


  $smtpuser="new2018oh";//SMTP服务器的用户帐号


  $smtppass="您的邮箱密码";//SMTP服务器的用户密码


  $mailtitle=$_POST['title'];//邮件主题


  $mailcontent="


  ".$_POST['content']."


  ";//邮件内容


  $mailtype="HTML";//邮件格式(HTML/TXT),TXT为文本邮件


  //************************配置信息****************************


  $smtp=newsmtp($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=false;//是否显示发送的调试信息


  $state=$smtp->sendmail($smtpemailto,$smtpusermail,$mailtitle,$mailcontent,$mailtype);


  echo"


  ";


  if($state==""){


  echo"对不起,邮件发送失败!请检查邮箱填写是否有误。";


  echo"点此返回";


  exit();


  }


  echo"恭喜!邮件发送成功!!";


  echo"点此返回";


  echo"";


  ?>


  最后还有smtp类无法发送邮件解决方法:


  偶然发现网站后台自动发送邮件功能不能用了,报这个错误:


  Tryingtosmtp.XX.com:25Error:Cannotconnencttorelayhostsmtp.XX.comError:()Error:Cannotsendemailtoweb@daixiaorui.comstate


  大概意思是:无法connenct中继主机smtp.XX.com错误:()错误:无法发送电子邮件


  找了很多资料后终于找到了解决方案,不是smtp类的问题,而就是linux配置的问题。原来是服务器的php.ini禁用了fsockopen函数。


  打开空间下的php.ini文件,linux空间一般都可以自定义php.ini,所以根目录下面一般会有这个文件。


  有两个地方可能禁用此函数:


  1.allow_url_fopen=On查看等于后面是否为ON,如果为OFF时函数将被禁用


  2.disable_functions=fsockopenpfsockopen(我的就是这样)这里应该去掉前面的“fsockopen”。使之变成:disable_functions=pfsockopen
