我是php编码的新手。 我的网站上有一个联系表，允许用户将文件作为附件发送到电子邮件。
从互联网上的参考文献中，我终于可以通过联系表发送电子邮件了。因此，问题是文件上传到服务器，但邮件到达时没有任何附件。
我创建了一个名为upload的文件夹，并且文件只在那儿。 我错过了什么吗？下面是我正在使用的代码：
HTML：
<form action="send_form_email.php" method="post" enctype="multipart/form-data" name="servicesform" id="servicesform" autocomplete="on">
<div class="control-group form-group">
<div class="controls">
<label class="contact-p1">Full Name:</label>
<input type="text" class="form-control" name="yourname" id="yourname" required data-validation-required-message="Please enter your name.">
<p class="help-block"></p>

因此，正如我在评论中所说，您应该使用Swift Mailer或PHPMailer。我对您的代码进行了一些修复，但是仍然有一些部分不是很好。
最重要的是：不要重新发明轮子-已经有很棒的邮件库。 mail()函数仅应用作库的基础层，切勿发送带有代码的电子邮件。
我做了什么：
filter_var()代替了正则表达式检查array()）替换了长数组语法（[]）我没有做的事情：
move_uploaded_file($_FILES["uploads"]["tmp_name"], __DIR__."/upload/" . $_FILES["uploads"]["name"]);的东西）无论如何，这是您的代码。

if (isset($_POST['email'])) {
