Insert multiple files into mysql - pdf

Question

I am trying to create a form whereby I can select multiple files (they will be pdfs) and insert the file and the file's name into the database.
Html form works beautifully:
<form action="" method="POST" enctype="multipart/form-data">
<input type="file" name="files[]" multiple/>
<input type="submit"/>
</form>
But I can't seem to make the php work with it:
if(isset($_POST['files[]'])){
$file_name = $_POST['files[]']['name'];
$file_size =$_POST['files[]']['size'];
$file_type=$_POST['files[]']['type'];}
$query="INSERT INTO upload_data (`FILE_NAME`,`FILE_SIZE`,`FILE_TYPE`) VALUES('$file_name','$file_size','$file_type'); ";
I also don't know how to insert the actual file, as opposed to just its properties. Any ideas?
UPDATE:
I got how to upload multiple files, and also multiple file names, but I cannot do both at the same time. Still need help. The code is:
<form action="" method="POST" enctype="multipart/form-data">
<input type="hidden" name="MAX_FILE_SIZE" value="30000" />
<input type="file" name="files[]" multiple/>
<input type="submit"/>
</form>
if(isset($_FILES['files'])){
foreach ($_FILES['files']['name'] as $filename) {
$query=mysql_query("INSERT INTO practice (name) VALUES('$filename')", $c) or die("six");
}
}
and
if(isset($_FILES['files'])){
foreach ($_FILES['files'] as $file) {
$query=mysql_query("INSERT INTO practice (file) VALUES('$file')", $c) or die("six");
}
}

To get information about uploaded files, you need to use the $_FILES variable instead of the $_POST variable : http://www.php.net/manual/en/features.file-upload.post-method.php
