下面这些发送电子邮件代码，用了一个imap与php教程自带的mail函数来实例，非常方法的，还有一种就是第三方插件哦，phpmailer来发送邮件。
<?php
//连接 IMAP 服务器链接，IMAP 的端口为 143。
$mbox = imap_open("{localhost:143}INBOX","user_id","password");
//连接POP3 服务器链接，POP3 的端口为 110。
$mbox = imap_open("{localhost/pop3:110}INBOX","user_id","password");
//连接NNTP 服务器链接，NNTP 的端口为 119。
$nntp = imap_open("{localhost/nntp:119}comp.test","","");
?>
<?php
//连接IMAP服务器
$mbox = imap_open("{imap.example.org}", "username", "password", OP_HALFOPEN)
or die("连接失败: " . imap_last_error());
$list = imap_getmailboxes($mbox, "{imap.example.org}", "*");
if (is_array($list)) {
foreach ($list as $key => $val) {
echo "($key) ";
echo imap_utf7_decode($val->name) . ",";
echo "'" . $val->delimiter . "',";
echo $val->attributes . "<br />n";
}
} else {
echo "imap_getmailboxes 失败: " . imap_last_error() . "n";
}
//关闭imap连接
imap_close($mbox);
?>
<?php
mail( "163@163.com", "欢迎你", "hello,你好! " );
?>
<?php
//定义边界线
$boundary = uniqid( "" );
//生成邮件头
$header = "From: $fromnContent-type: multipart/mixed;
boundary="$boundary"nX-Mailer:PHPnX-Priority:3";
//获取附件文件的MIME类型
$mimetype = mime_content_type('test.zip')
//获取附件文件的名字
$attach = 'test.zip'
//对附件文件进行编码和切分
$fp = fopen($attach, "r");
$content = fread($fp, filesize($attach));
$content = chunk_split( base64_encode($content) );
//生成邮件主体
$body ="

$message

//发送邮件
