  2. echo send_mail('someone@126.com','only a test mail for test php mail function','一封垃圾邮件');  
  3. echo time();  
  4.  
  5. function send_mail($to, $subject = 'No subject', $body) {  
  6. $loc_host = "mail.server"; //发信计算机名,可随意  
  7. $smtp_acc = "smp@163.com"; //Smtp认证的用户名  
  8. $smtp_pass="pwdpwd"; //Smtp认证的密码,一般等同pop3密码  
  9. $smtp_host="smtp.163.com"; //SMTP服务器地址,类似 smtp.tom.com  
  10. $from="smp@163.com"; //发信人Email地址,你的发信信箱地址  
  11. $deliver=$smtp_acc; //回复到指定邮箱  
  12. $headers = "Content-Type: text/plain; charset="gb2312"rnContent-Transfer-Encoding: base64";  
  13. $lb="rn"; //linebreak   
  14. $hdr = explode($lb,$headers); //解析后的hdr  
  15. if($body) {$bdy = preg_replace("/^./","..",explode($lb,$body));}//解析后的Body  
  16.  
  17. $smtp = array(  
  18. //1、EHLO,期待返回220或者250  
  19. array("EHLO ".$loc_host.$lb,"220,250","HELO error: "),  
  20. //2、发送Auth Login,期待返回334  
  21. array("AUTH LOGIN".$lb,"334","AUTH error:"),  
  22. //3、发送经过Base64编码的用户名,期待返回334  
  23. array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "),  
  24. //4、发送经过Base64编码的密码,期待返回235  
  25. array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : "));  
  26. //5、发送Mail From,期待返回250  
  27. $smtp[] = array("MAIL FROM: ".$from.">".$lb,"250","MAIL FROM error: ");  
  28. //6、发送Rcpt To。期待返回250  
  29. $smtp[] = array("RCPT TO: ".$to.">".$lb,"250","RCPT TO error: ");  
  30. //7、发送DATA,期待返回354  
  31. $smtp[] = array("DATA".$lb,"354","DATA error: ");  
  32. //8.0、发送From  
  33. $smtp[] = array("From: ".$deliver.$lb,"","");  
  34. //8.2、发送To  
  35. $smtp[] = array("To: ".$to.$lb,"","");  
  36. //8.1、发送标题  
  37. $smtp[] = array("Subject: ".$subject.$lb,"","");  
  38. //8.3、发送其他Header内容  
  39. foreach($hdr as $h) {$smtp[] = array($h.$lb,"","");}  
  40. //8.4、发送一个空行,结束Header发送  
  41. $smtp[] = array($lb,"","");  
  42. //8.5、发送信件主体  
  43. if($bdy) {foreach($bdy as $b) {$smtp[] = array(base64_encode($b.$lb).$lb,"","");}}  
  44. //9、发送“.”表示信件结束,期待返回250  
  45. $smtp[] = array(".".$lb,"250","DATA(end)error: ");  
  46. //10、发送Quit,退出,期待返回221  
  47. $smtp[] = array("QUIT".$lb,"221","QUIT error: ");  
  48.  
  49. //打开smtp服务器端口  
  50. $fp = @fsockopen($smtp_host, 25);  
  51. if (!$fp) echo "b>Error:b> Cannot conect to ".$smtp_host."br>";  
  52. while($result = @fgets($fp, 1024)){if(substr($result,3,1) == " ") { break; }}  
  53.  
  54. $result_str="";  
  55. //发送smtp数组中的命令/数据  
  56. foreach($smtp as $req){  
  57. //发送信息  
  58. @fputs($fp, $req[0]);  
  59. //如果需要接收服务器返回信息,则  
  60. if($req[1]){  
  61. //接收信息  
  62. while($result = @fgets($fp, 1024)){  
  63. if(substr($result,3,1) == " ") { break; }  
  64. };  
  65. if (!strstr($req[1],substr($result,0,3))){  
  66. $result_str.=$req[2].$result."br>";  
  67. }  
  68. }  
  69. }  
  70. //关闭连接  
  71. @fclose($fp);  
  72. return $result_str;  
  73. }  

希望上面这段代码示例能让大家充分掌握PHP发送邮件函数的运用。
