php如何发送邮件
你好，用这个邮件类，需要在调用时，填写一个smtp服务器和你的用户名密码。
?php
set_time_limit(600);

class smail {
//您的SMTP 服务器供应商，可以是域名或IP地址
var $smtp = "";
//SMTP需要要身份验证设值为 1 不需要身份验证值为 0，现在大多数的SMTP服务商都要验证，如不清楚请与你的smtp 服务商联系。
var $check = 1;
//您的email帐号名称
var $username = "";
//您的email密码
var $password = "";
//此email 必需是发信服务器上的email
var $s_from = "";
/*

如何正确运用PHP发送邮件函数
PHP发送邮件函数的应用代码示例：
#echo send_mail($_POST["email"],$tosubject,$_POST["errortext"]);
echo send_mail('someone@126.com','only a test mail for test php mail function','一封垃圾邮件');
echo time();
function send_mail($to, $subject = 'No subject', $body) {
$loc_host = "mail.server"; //发信计算机名，可随意
$smtp_acc = "smp@163.com"; //Smtp认证的用户名
$smtp_pass="pwdpwd"; //Smtp认证的密码，一般等同pop3密码
$smtp_host="smtp.163.com"; //SMTP服务器地址，类似 smtp.tom.com
$from="smp@163.com"; //发信人Email地址，你的发信信箱地址
$deliver=$smtp_acc; //回复到指定邮箱
$headers = "Content-Type: text/plain; charset="gb2312"rnContent-Transfer-Encoding: base64";
$lb="rn"; //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
$smtp[] = array("From: ".$deliver.$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 (!$fp) echo "bError:/b Cannot conect to ".$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);
return $result_str;
}
希望上面这段代码示例能让大家充分掌握PHP发送邮件函数的运用。
怎么用php的mail函数发邮件
function sendMail($to, $title, $content) {
Vendor('PHPMailer.PHPMailerAutoload');
$mail = new PHPMailer(); //实例化
$mail-IsSMTP(); // 启用SMTP
$mail-Host=C('MAIL_HOST'); //smtp服务器的名称（这里以QQ邮箱为例）
$mail-SMTPAuth = C('MAIL_SMTPAUTH'); //启用smtp认证
$mail-Username = C('MAIL_USERNAME'); //你的邮箱名
$mail-Password = C('MAIL_PASSWORD') ; //邮箱密码
$mail-From = C('MAIL_FROM'); //发件人地址（也就是你的邮箱地址）
$mail-FromName = C('MAIL_FROMNAME'); //发件人姓名
$mail-AddAddress($to,"尊敬的客户");
$mail-WordWrap = 50; //设置每行字符长度
$mail-IsHTML(C('MAIL_ISHTML')); // 是否HTML格式邮件
$mail-CharSet=C('MAIL_CHARSET'); //设置邮件编码
$mail-Subject =$title; //邮件主题
$mail-Body = $content; //邮件内容
$mail-AltBody = ""; //邮件正文不支持HTML的备用显示
$relt = $mail-Send();
if(!$relt) {
writeLog('发送邮件错误，错误信息:'. $mail-ErrorInfo, 1, '发送邮箱失败');
}
return($relt);
}
这个是thinkphp版本的。
