        PHP開發中使用smtp類輕松的發送電子郵件(源碼)

        發布人:扣丁學習 時間:2020-11-04 來源:工程師 發布文章

          在現如今,作為PHP網站開發程序員需要接觸到各種程序接口,比如網站修改密碼使用smtp類輕松的發送電子郵件,首先smtp類發送郵件的方法其實很簡單,也很穩定,類是別人已經寫好的了,你只需要調用就行了。幾行簡單的配置就能發郵件,下面我們一起來看一下吧。

          email.class.php文件

          }


          ?>


          發送郵箱的php文件


          require_once"email.class.php";


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


          $smtpserver="smtp.XX.com";//SMTP服務器


          $smtpserverport=25;//SMTP服務器端口


          $smtpusermail="new2018oh@XX.com";//SMTP服務器的用戶郵箱


          $smtpemailto=$_POST['toemail'];//發送給誰


          $smtpuser="new2018oh";//SMTP服務器的用戶帳號


          $smtppass="您的郵箱密碼";//SMTP服務器的用戶密碼


          $mailtitle=$_POST['title'];//郵件主題


          $mailcontent="


          ".$_POST['content']."


          ";//郵件內容


          $mailtype="HTML";//郵件格式(HTML/TXT),TXT為文本郵件


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


          $smtp=newsmtp($smtpserver,$smtpserverport,true,$smtpuser,$smtppass);//這里面的一個true是表示使用身份驗證,否則不使用身份驗證.


          $smtp->debug=false;//是否顯示發送的調試信息


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


          echo"


          ";


          if($state==""){


          echo"對不起,郵件發送失敗!請檢查郵箱填寫是否有誤。";


          echo"點此返回";


          exit();


          }


          echo"恭喜!郵件發送成功!!";


          echo"點此返回";


          echo"";


          ?>


          最后還有smtp類無法發送郵件解決方法:


          偶然發現網站后臺自動發送郵件功能不能用了,報這個錯誤:


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


          大概意思是:無法connenct中繼主機smtp.XX.com錯誤:()錯誤:無法發送電子郵件


          找了很多資料后終于找到了解決方案,不是smtp類的問題,而就是linux配置的問題。原來是服務器的php.ini禁用了fsockopen函數。


          打開空間下的php.ini文件,linux空間一般都可以自定義php.ini,所以根目錄下面一般會有這個文件。


          有兩個地方可能禁用此函數:


          1.allow_url_fopen=On查看等于后面是否為ON,如果為OFF時函數將被禁用


          2.disable_functions=fsockopenpfsockopen(我的就是這樣)這里應該去掉前面的“fsockopen”。使之變成:disable_functions=pfsockopen
