php发送邮件email

1.phpmailer,很好用,无论原生还是放到框架下,都没问题

<?php
header("content-type:text/html;charset=utf-8");
include("class.phpmailer.php");
include("class.smtp.php");
$mail = new PHPMailer(); 
$mail->IsSMTP(); // send via SMTP 
$mail->Host = "smtp.163.com"; // SMTP servers 
$mail->SMTPAuth = true; // turn on SMTP authentication 
$mail->Username = "*********"; // SMTP username 注意:普通邮件认证不需要加 @域名 
$mail->Password = "*****"; // SMTP password 
$mail->From = "******@163.com"; // 发件人邮箱 
$mail->FromName = "zph"; // 发件人 
$mail->CharSet = "utf-8"; // 这里指定字符集! 
$mail->Encoding = "base64"; 
$mail->AddAddress("******@163.com","toyou"); // 收件人邮箱和姓名 
$mail->AddReplyTo("******@163.com","wo"); 
//$mail->WordWrap = 50; // set word wrap 换行字数 
//$mail->AddAttachment("/var/tmp/file.tar.gz"); // attachment 附件 
//$mail->AddAttachment("/tmp/image.jpg", "new.jpg"); 
$mail->IsHTML(true); // send as HTML 
// 邮件主题 
$subject="测试";
$mail->Subject = $subject; 
// 邮件内容 
$mail->Body = " 
<p>点击激活</p> 
<a href='#'>点击激活</a>
"; 
$mail->AltBody ="text/html"; 
if(!$mail->Send()) 
{ 
echo "邮件发送有误 <p>"; 
echo "邮件错误信息: " . $mail->ErrorInfo; 
exit; 
} 
else { 
echo "邮件发送成功!<br />"; 
}


2.当使用php原生mail()函数的时候,需要安装sendmail,linux一般已经安装sendmail,可以直接使用mail(),如果是windows需要先安装。

3.当使用ci框架的时候,如下

public function sendemail()
{	
	$config = array('protocol'=>'smtp',
		'smtp_host' => 'smtp.163.com',
		'smtp_user' => 'yourname',
		'smtp_pass' => '*****',
		'smtp_port' => '25',
		'_smtp_auth' => TRUE,
		'wordwrap' => TRUE,
		'charset' => 'iso-8859-1'

	);
	$this->load->library('email', $config);
	$this->email->from('[email protected]', 'Your Name');
	$this->email->to('[email protected]');
	$this->email->subject('Email Test');
	$this->email->message('Testing the email class.');
	$this->email->send();
}
