虚拟主机PHP程序使用fsockopen方式发信代码示例参考
发布日期:2015-12-2 9:12:59

  PHP程序在虚拟主机中可以通过调用fsockopen方式使用SMTP认证邮箱发信,相关程序代码参考如下:

  echo send_mail('此处为收件人邮箱','发信测试','测试测试测试测试测试测试');

  function send_mail($to, $subject = 'No subject', $body) {

  $loc_host = "test"; //发信计算机名,可随意

  $smtp_acc = "

  test@hichina.com"; //Smtp认证的用户名,类似fuweng@im286.com,或者fuweng

  $smtp_pass="test"; //Smtp认证的密码,一般等同pop3密码

  $smtp_host="mx.hichina.com"; //SMTP服务器地址,类似 smtp.tom.com

  $from="test@hichina.com"; //发信人Email地址,你的发信信箱地址

  $headers = "Content-Type: text/plain; charset=\"gb2312\"\r\nContent-Transfer-Encoding: base64";

  $lb="\r\n"; //linebreak

  $hdr = explode($lb,$headers); //解析后的hdr

  if($body) {$bdy = preg_replace("/^\./","..",explode($lb,$body));}//解析后的Body

  $smtp = array(

  //1、EHLO,期待返回220或者250

  array("EHLO ".$loc_host.$lb,"220,250","HELO error: "),

  //2、发送Auth Login,期待返回334

  array("AUTH LOGIN".$lb,"334","AUTH error:"),

  //3、发送经过Base64编码的用户名,期待返回334

  array(base64_encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "),

  //4、发送经过Base64编码的密码,期待返回235

  array(base64_encode($smtp_pass).$lb,"235","AUTHENTIFICATION error : "));

  //5、发送Mail From,期待返回250

  $smtp[] = array("MAIL FROM: <".$from.">".$lb,"250","MAIL FROM error: ");

  //6、发送Rcpt To。期待返回250

  $smtp[] = array("RCPT TO: <".$to.">".$lb,"250","RCPT TO error: ");

  //7、发送DATA,期待返回354

  $smtp[] = array("DATA".$lb,"354","DATA error: ");

  //8.0、发送From

  $smtp[] = array("From: ".$from.$lb,"","");

  //8.2、发送To

  $smtp[] = array("To: ".$to.$lb,"","");

  //8.1、发送标题

  $smtp[] = array("Subject: ".$subject.$lb,"","");

  //8.3、发送其他Header内容

  foreach($hdr as $h) {$smtp[] = array($h.$lb,"","");}

  //8.4、发送一个空行,结束Header发送

  $smtp[] = array($lb,"","");

  //8.5、发送信件主体

  if($bdy) {foreach($bdy as $b) {$smtp[] = array(base64_encode($b.$lb).$lb,"","");}}

  //9、发送“.”表示信件结束,期待返回250

  $smtp[] = array(".".$lb,"250","DATA(end)error: ");

  //10、发送Quit,退出,期待返回221

  $smtp[] = array("QUIT".$lb,"221","QUIT error: ");

  //打开smtp服务器端口

  $fp = @fsockopen($smtp_host, 25);

  if (!$fp) echo "Error: Cannot conect to ".$smtp_host."

  ";

  while($result = @fgets($fp, 1024)){if(substr($result,3,1) == " ") { break; }}

  $result_str="";

  //发送smtp数组中的命令/数据

  foreach($smtp as $req){

  //发送信息

  @fputs($fp, $req[0]);

  //如果需要接收服务器返回信息,则

  if($req[1]){

  //接收信息

  while($result = @fgets($fp, 1024)){

  if(substr($result,3,1) == " ") { break; }

  };

  if (!strstr($req[1],substr($result,0,3))){

  $result_str.=$req[2].$result."

  ";

  }

  }

  }

  //关闭连接

  @fclose($fp);

  return $result_str;

  }

  ?>
