attachment is not working in mail function wordpress - php

Question

Text mail works fine but I want to attach file too.
Attachment is not working.
My code is:
<form method="post" enctype="multipart/form-data">
<input name="filepc" type="file" id="filepc" class="listEm" />
</form>
if (isset($_POST['submit'])) {
$attachments = '';
if (!empty($_FILES['filepc']['tmp_name'])) {
$attachments = array($_FILES['filepc']['name']);
}
headers = "From:" . $your_email . " < " . $email . ">" . "\r\n";
$headers .= "Reply - To:" . $ct_email . "\r\n";
$headers .= "Content-Disposition: attachment; filename=\"".$attachments."\"\r\n\r\n";
//$headers = "Bcc: someone#domain . com" . "\r\n";
$headers = "X - Mailer: PHP / " . phpversion();
mail($to , $subject , $msg , $headers,$attachments);
$successMsg = '<h5 style="color:red;">Sent successfully</h5>';
// }
}
Above code works but file is not attached. Please help me find the solution for this problem.

if(!empty($_FILES['resume']['name'])) {
$mime_boundary="==Multipart_Boundary_x".md5(mt_rand())."x";
$tmp_name = $_FILES['resume']['tmp_name'];
$type = $_FILES['resume']['type'];
$file_name = $_FILES['resume']['name'];
$size = $_FILES['resume']['size'];
// Check to make sure that it is an uploaded file and not a system file
if(is_uploaded_file($tmp_name)){
// Now Open the file for a binary read
$file = fopen($tmp_name,'rb');
// Now read the file content into a variable
$data = fread($file,filesize($tmp_name));
// close the file
fclose($file);
// Now we need to encode it and split it into acceptable length lines
$data = chunk_split(base64_encode($data));
}
$mybody = "This is a multi-part message in MIME format.\n\n" .
"--{$mime_boundary}\n" .
"Content-Type: text/html; charset=\"iso-8859-1\"\n" .
"Content-Transfer-Encoding: 7bit\n\n" .
$mybody . "\n\n";
$headers = "From: $from\r\n" .
"MIME-Version: 1.0\r\n" .
"Content-Type: multipart/mixed;\r\n" .
" boundary=\"{$mime_boundary}\"";
$mybody .= "--{$mime_boundary}\n" .
"Content-Type: {$type};\n" .
" name=\"{$file_name}\"\n" .
//"Content-Disposition: attachment;\n" .
//" filename=\"{$fileatt_name}\"\n" .
"Content-Transfer-Encoding: base64\n\n" .
$data . "\n\n" .
"--{$mime_boundary}--\n";
$bodys .= "$mybody <br>";
$subject = "Attachment";
$body = $body . $bodys;
mail($to, $subject, $body, $headers);
}
