使用sock技术发邮件,无需服务器支持。速度快!!
function send_mail($to,$subject,$body) { /////////////Smtp信息,可以修改成你的,////////// $loc_host = "longbill"; //发信计算机名,可随意 $smtp_acc = "longbill.mail"; //Smtp认证的用户名, $smtp_pass = "longbill"; //Smtp认证的密码, $smtp_host = "smtp.163.com"; //SMTP服务器地址, $from = "longbill.mail@163.com"; //要与smtp信息对应 ,否则会失败 /////////////Smtp信息完////////////////////////////////// $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 (!$fp) echo "<b>Error:</b> Cannot conect to ".$smtp_host."<br>"; 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].$result."<br>"; } } } //关闭连接 @fclose($fp); if ($result_str==""){return "发送成功!!";}else {return $result_str;} }
