我的任务
分享请唠叨老大进来帮帮忙（附代码）
为什么我的邮件系统发送不成功呢？而且附件也不能发出去，请帮我看看哪里出错了。代码如下：
<?php
/*
$to 目标
$subject 主题
$message 正文
$from 发自
$content_type 类型
$attache 附件，文件名放在数组中
*/
if($check=="yes")
{
$email = $_POST['email'];
$email = trim("$email");
$to="loveclf@21cn.com";
$message = "hello";
function mail2( $to, $subject, $message, $from, $content_type, $attache="") {
if(!empty($from)) $head = "From: $from\n";
if(empty($content_type)) $content_type = "text/plain";
if(is_array($attache)) {
$boundary = "===" . md5(uniqid("")) . "===";
$head .= "Mime-Version: 1.0\nContent-Type: multipart/mixed; boundary=\"";
$head .= "$boundary\"\n\nThis is a multi-part message in MIME format.\n\n";
$head .= "--$boundary\n";
$head .= "Content-Type: $content_type\n";
$head .= "\n$message\n\n";
while(list($key, $val) = each($attache)) {
$fd = fopen("$val", "r") or die("unable to open file $val");
$contents = chunk_split(base64_encode(fread($fd,filesize("$val"))));
fclose($fd);
$head .= "--$boundary\n";
$head .= "Content-Type: application/octet-stream; name=\"".basename($val);
$head .= "\"\nContent-Transfer-Encoding: BASE64\n";
$head .= "Content-Disposition: attachment; filename=\"".basename($val);
$head .= "\"\n\n" . $contents . "\n\n";
}
$head .= "--" . $boundary . "--\n\n";
}else{
if(!empty($content_type)) {
$head .= "Content-Type: $content_type\n";
$head .= "\n$message\n";
}
}
return mail($to,$subject,"",$head );
}
mail2("$email","",$message,"","",array("a.txt"));
}
?>
