I want to know how to send email attachments using jquery file uploads

from this plugin https://blueimp.github.io/jQuery-File-Upload/

is there a way to do that. or i have to use regular input files

here is my script for sending email

<?php
if(isset($_FILES) && (bool) $_FILES) {
    $AllowedExtensions = ["pdf","doc","docx","gif","jpeg","jpg","png","rtf","txt"];
    $files = [];
    $server_file = [];
    foreach($_FILES as $name => $file) {
        $file_name = $file["name"];
        $file_temp = $file["tmp_name"];
        foreach($file_name as $key) {
            $path_parts = pathinfo($key);
            $extension = strtolower($path_parts["extension"]);
            if(!in_array($extension, $AllowedExtensions)) { die("Extension not allowed"); }
            $server_file[] = "uploads/{$path_parts["basename"]}";
        }
        for($i = 0; $i<count($file_temp); $i++) { move_uploaded_file($file_temp[$i], $server_file[$i]); }
    }
    $to = "[e-mail]";
    $from = "[e-mail]";
    $subject ="test attachment";
    $message = "this is a test message";
    $headers = "From: $from";
    $semi_rand = md5(time());
    $mime_boundary = "==Multipart_Boundary_x{$semi_rand}x";
    $headers .= "
MIME-Version: 1.0
" . "Content-Type: multipart/mixed;
" . " boundary=\"{$mime_boundary}\"";
    $message = "This is a multi-part message in MIME format.

" . "--{$mime_boundary}
" . "Content-Type: text/plain; charset=\"iso-8859-1\"
" . "Content-Transfer-Encoding: 7bit

" . $message . "

";
    $message .= "--{$mime_boundary}
";
    $FfilenameCount = 0;
    for($i = 0; $i<count($server_file); $i++) {
        $afile = fopen($server_file[$i],"rb");
        $data = fread($afile,filesize($server_file[$i]));
        fclose($afile);
        $data = chunk_split(base64_encode($data));
        $name = $file_name[$i];
        $message .= "Content-Type: {\"application/octet-stream\"};
" . " name=\"$name\"
" .
            "Content-Disposition: attachment;
" . " filename=\"$name\"
" .
            "Content-Transfer-Encoding: base64

" . $data . "

";
        $message .= "--{$mime_boundary}
";
    }
    if(mail($to, $subject, $message, $headers)) {
        echo "<p>mail sent to $to!</p>";
    } else {
        echo "<p>mail could not be sent!</p>";
    }
}

?>
