php我們可以使用系統的mail函數去發送郵件 但是需要配置一下郵件環境 這里選擇使用PHPMailer 這樣比較方便
首先下載PHPMailer:https://github.com/Synchro/PHPMailer
然后將下載好的文件夾解壓放到根目錄下即可
然后調用mail函數發送郵件:
比如:
<?php $to = "542633273@qq.com"; $subject = "Test mail"; $message = "Hello! This is a dsdsimple email message."; $from = "542633273@qq.com"; $headers = "From: $from"; mail($to,$subject,$message,$headers); echo "Mail Sent."; ?>
--------------------------更新:上面的方法雖然簡單方便,但是有個問題就是不穩地,有時候發送到垃圾郵箱里,有時候收不到郵件,所以不太實用.---------------------------
以下方法,主要是使用了一個障眼法,即發件人郵箱與收件人郵箱都是自己設定的,而真正的發件人郵箱是以內容的形式發送過去的,即用戶在填寫內容和自己郵箱信息后點擊發送按鈕,后台真正是通過我自己好郵箱A發送到我自己的郵箱B的 只不過用戶真正有郵箱會通過內容的形式反映出來.這樣做可以保證郵件的穩定性以及不會被當做垃圾郵件處理
/** * 注：本郵件類都是經過我測試成功了的，如果大家發送郵件的時候遇到了失敗的問題，請從以下幾點排查： * 1. 用戶名和密碼是否正確； * 2. 檢查郵箱設置是否啟用了smtp服務； * 3. 是否是php環境的問題導致； * 4. $smtp->debug = false改為true，可以顯示錯誤信息，然后可以復制報錯信息到網上搜一下錯誤的原因； * 5. 如果還是不能解決，可以訪問：http://www.daixiaorui.com/read/16.html#viewpl * 下面的評論中，可能有你要找的答案。 */ require_once "email.class.php"; //******************** 配置信息 ******************************** $smtpserver = "smtp.126.com";//SMTP服務器 $smtpserverport =25;//SMTP服務器端口 $smtpusermail = "nnnnnnn@126.com";//發件人郵箱 $smtpemailto = "mmmmmmm@126.com";//發送給誰 $smtpuser = "nnnnnnn@126.com";//SMTP服務器的用戶帳號 $smtppass = "nnnnnnn";//SMTP服務器的用戶密碼 $mailtitle = $subject ;//郵件主題 $mailcontent = "<h3>".$message."</h3>"."<br/>"."<h5>發件人郵箱:"."$email"."<br/><br/><br/>"."發件人昵稱:"."$name"."</h5>";//郵件內容 $mailtype = "HTML";//郵件格式（HTML/TXT）,TXT為文本郵件 //************************ 配置信息 **************************** $smtp = new smtp($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, $mailtype); if($state==""){ echo"<br/><br/><br/><br/><br/><br/><br/><br/><br/>"; echo "<center><h1>郵件發送失敗</h1></center>"; echo "<center><h3>請檢查郵箱是否正確!</h3></center>"; echo "<center><h5><a href='../index.html'>馬上返回</a></h5></cener>"; exit(); }else{ echo"<br/><br/><br/><br/><br/><br/><br/><br/><br/>"; echo "<center><h1>$name,已收到您的來信</h1></center>"; echo "<center><h3>我會盡快回復的</h3></center>"; echo "<center><h5><a href='../index.html'>馬上返回</a></h5></cener>"; }
