PHP中三種方法發送郵件的代碼

我們利用了三種php教程發送郵件實常式序哦，下面一個個來實例各種發送的發送郵件哦。

if(send_mail('test@qq.com','郵件主題','郵件內容')==""){
echo "發送成功！ <br>";
} else{
echo "發送失敗！ <br>";
}

<?php
$to = "test@test.com";
$subject = "Test Subject";
$message = "This is the test email.";
$from = "youremail@yourdomain.com";
$headers = "From: $from";
mail($to,$subject,$message,$headers);
?>

<?php
function send_mail($to, $subject = 'No subject', $body) {
$loc_host = "im286"; 發信電腦名稱，可隨意
$smtp_acc = "test@126.com"; Smtp認證的使用者名
$smtp_pass="******"; Smtp認證的密碼，一般等同pop3密碼
$smtp_host="smtp.126.com"; SMTP伺服器位址，類似 smtp.tom.com
$from="test@126.com"; 發信人Email位址，你的發信信箱位址
$headers = "Content-Type: text/plain; charset="utf-8"rnContent-Transfer-Encoding: base64";
$lb="rn"; linebreak

$hdr=explode($lb,$headers); //解析後的hdr
if($body){$bdy = preg_replace("/^./","..",explode($lb,$body));} 解析後的Body

$smtp = array(
//1、EHLO，期待返回220或者250
array("EHLO ".$loc_host.$lb,"220,250","HELO error: "),
//2、發送Auth L ogin，期待返回334
array("AUTH LOGIN".$lb,"334","AUTH error:"),
//3、發送經過Base64編碼的使用者名，期待返回334
array(base64_ encode($smtp_acc).$lb,"334","AUTHENTIFICATION error : "),
//4、發送經過Base64編碼的密碼，期待返回235
array(base64_encode($ smtp_pass).$lb,"235","AUTHENTIFICATION error : "));
//5、發送Mail From，期待返回250
$smtp[] = array("MAIL FROM: <".$from." >".$lb,"250","MAIL FROM error: ");
//6、發送Rcpt To。 期待返回250
$smtp[] = array("RCPT TO: <".$to." >".$lb,"250","RCPT TO error: ");
//7、發送DATA，期待返回354
$smtp[] = array("DATA".$lb,"354","DATA error: ");
//8.0、發送From
$smtp[] = array("From: ".$from.$lb,"","");
//8.2、發送To
$smtp[] = array("To: ".$to.$lb,"","");
//8.1、發送標題
$smtp[] = array("Subject: ".$subject.$lb,"","");
//8.3、發送其他Header內容
foreach($hdr as $h) {$smtp[] = array($h.$lb,"","");}
//8.4、發送一個空行，結束Header發送
$smtp[] = array($lb,"","");
//8.5、發送信件主體
if($bdy) {foreach($bdy as $b) {$smtp[] = array(base64_encode($b.$lb).$lb,"","");}}
//9、發送「.」 表示信件結束，期待返回250
$smtp[] = array(".". $lb,"250","DATA(end)error: ");
//10、發送Quit，退出，期待返回221
$smtp[] = array("QUIT".$lb,"221","QUIT error: ");

打開smtp伺服器埠
$fp=@fsockopen($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; }}

$result_str="";
發送smtp陣列中的命令/資料
foreach($smtp as $req){
發送資訊
@fputs($fp, $req[0]);
如果需要接收伺服器返回資訊，則
if($req[1]){
接收資訊
while($result = @fgets($fp, 1024)){
if(substr($result,3,1) == " ") { break; }
};
if (!strstr($req[1],substr($result,0,3))){
$result_str.=$req[2].$result." <br>";
}
}
}
關閉連接
@fclose($fp);
return $result_str;
}
?>
