我想知道我是否可以选择你的大脑。
我的网站上有一个邮件脚本，我可以用它来发送带有一个附件的电子邮件。发送一个附件就可以了。
我希望能够发送包含多个附件的电子邮件，但我遇到了问题。
这是我在表单中的文件选择框：
<input type="file" name="attachment[]" id="attachment[]" multiple onfocus="this.style.backgroundColor='#e7e7e7'" onblur="this.style.backgroundColor='#ffffff'"/>
然后，当选择文件时，这是处理它的php：
if (!empty($_FILES['attachment']['name']))
{
if(count($_FILES['attachment']['name'])>0)
{
$count = 0;
foreach ($_FILES['attachment']['name'] as $file)
{
$name_of_file = $_FILES['attachment']['name'][$count];
$file_name = $guid." - ".$name_of_file;
$temp_name = $_FILES['attachment']['tmp_name'][$count];
$file_type = $_FILES['attachment']['type'][$count];
$file_size = $_FILES['attachment']['size'][$count];
$count++;
if ($file_size > 2048000)
{
header ("refresh: 5; url=attach.php");
include ("header.php");
echo "File size is to big. Size must be no bigger than 2Mb. Please go <a href='attach.php'>back</a>";
include ("footer.php");
exit;
}
else
{
$pics = array(".bmp", ".gif", ".jpg", "jpeg", ".png"); //5
$docs = array(".doc", "docx", ".odt", ".pdf", ".ppt", "pptx", ".rtf", ".txt", ".xls", "xlsx"); //10
$misc = array(".csv", ".htm", "html", ".php", ".pkt", ".rar", ".sql", ".xpi", ".zip"); //9
$base = basename($file_name);
$extension = substr($base, strlen($base)-4, strlen($base));
$extension = strtolower($extension);

我遇到的问题是当我尝试以这种方式发送电子邮件时，我收到以下错误：
Warning: Invalid argument supplied for foreach() in /home/flattley/public_html/chriswilcox/cab/attach.php on line 150
第150行是：
foreach ($file as $files)
我只是不知道自己哪里出错了。如果我没有foreach循环，那么它就不会发送，或者它只会发送第一个文件。
我知道我可以使用像phpmailer这样的东西，但我想能够自己做这件事。我只是看不出我错在哪里。
我在家里的本地apache上尝试过这个脚本而没有邮寄它，它上传并移动多个文件就好 - 就像在我的主机上一样。当我添加邮件选项时，它都变成了梨形。
非常感谢您提供的任何帮助

如果你回头看看你的代码：
foreach ($_FILES['attachment']['name'] as $file)
$file已经是单个文件名。它不是一个数组。正如我提到的php documentation。
我在您的代码中看到，您尝试获取上传文件的内容。要做到这一点，你可以这样做：
foreach($_FILES['attachment']['tmp_name'] as $eachFile){
$content = chunk_split(base64_encode(file_get_contents($file)));
$uid = md5(uniqid(time()));
$header = "From: ".$from."\r\n";
$header .= "Reply-To: ".$from."\r\n";
$header .= "Bcc: ".$bcc."\r\n";
$header .= "MIME-Version: 1.0\r\n";
$header .= "Content-Type: multipart/mixed; boundary=\"".$uid."\"\r\n\r\n";
$header .= "This is a multi-part message in MIME format. \r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-Transfer-Encoding: 7bit\r\n\r\n";
$header .= $message1."\r\n";
$header .= "--".$uid."\r\n";
$header .= "Content-Type: ".$file_type."; name=\"".$file_name."\"\r\n";
$header .= "Content-Transfer-Encoding: base64\r\n";
$header .= "Content-Disposition: attachment; filename=\"".$file_name."\"\r\n\r\n";
$header .= $content."\r\n";
}
