[Resolved] File Uploads and Arrays?

[The Hobo]

I have a form somewhat like this:

<form action="index.php" method="post">
    1. <input type="file" name="f[]"><br>
    2. <input type="file" name="f[]"><br>
    3. <input type="file" name="f[]"><br>

    <input type="submit" value=" Send ">
</form>

Now, how can I tell how many, if any, of these include files?

I tried something like:

echo count($_FILES['f']);
//and:
echo count($_POST['f']);

But neither work.

I guess I'm going to assume that I can't use arrays with file types. The following code works for the text type, but not the file:

<?php
    if (isset($_POST['submit'])) {
        echo $_FILES['my_file'][0]['type'] . '<br>';
        echo $_POST['my_text'][0];
    } else {
        echo '<form action="testupload.php" method="post" enctype="multipart/form-data">
            <input type="file" name="my_file[]">
            <br>
            <input type="text" name="my_text[]">
            <br>
            <input type="submit" name="submit" value=" Send ">
        </form>';
    }
?>

Ah ha!

$_FILES['my_file'][0]['type']; //should be:
$_FILES['my_file']['type'][0];
