This array thing is confusing me!

Hi --
Here's my problem... I created a form to upload multiple files (using $FILES). I can get the files where they need to go by doing:

move_uploaded_file ($_FILES['file']['tmp_name'][0], $up_path . $_FILES['file']['name'][0]);
move_uploaded_file ($_FILES['file']['tmp_name'][1], $up_path . $_FILES['file']['name'][1]);
move_uploaded_file ($_FILES['file']['tmp_name'][2], $up_path . $_FILES['file']['name'][2]);
..
...so on and so on...

Not very efficient so I'm trying to do it with a 'foreach' ... but that's where I'm stuck. I'm a little confused on how it handles the array.
This is what I have so far:

					
$tmp_file = $_FILES['file']['tmp_name'];
$filename = $_FILES['file']['name'];

foreach ($tmp_file as $x) {
						move_uploaded_file($tmp_file, $dl_path . $filename);
echo "Uploaded: $filename<br>";				
}

Needless to say it's not working.... what's the correct syntax to do this?

Hopefully what I'm trying to explain makes since to someone because this has been driving me crazy all evening... any help is always appreciated!

foreach loops are awesome! I only have a second to post, but let me give you the jist of how they work.

They obviously loop through arrays. Throughout each iteration of the loop, you have access that a specific entry in the array. You can access that specific key and the corresponding value. So what you do is this:

foreach($array as $key => $value) {
   echo "The Key is " . $key . " and the Value is " . $value . "<br>";
}

In the example above, $array is the actual array. $key is the variable that will contain the array key for each record, and $value will contain the value that that array key holds. So lets say you had the following array

0 => dogs
1 => cats
2 => horses
3 => bugs

The foreach loop above would output

The key is 0 and the Value is dogs
The key is 1 and the Value is cats
The key is 2 and the Value is horses
The key is 3 and the Value is bugs

Get it? Now, keep in mind $key and $value are the names you provide. For all php cares, you can name those whatever you want; just refer back to the name you use.

foreach($array as $number => $animal) {
   echo "The Key is " . $number . " and the Value is " . $animal . "<br>";
}

This would produce the exact same output.

Hope this helped!

Of course, since they're numerically indexed, and you know how many there are (count($_FILES['file']['name'])), a simple for() loop is sufficient:

$tmp_files = $_FILES['file']['tmp_name'];
$filenames = $_FILES['file']['name'];
$count_files = count($_FILES['file']['name']);
for ($i=0; $i<$count_files; $i++) {
	move_uploaded_file($tmp_file[$i], $dl_path . $filename[$i]);
	echo "Uploaded: {$filename[$i]}<br>";
}

That way you can be explicit about having e.g. the second filename paired with the second tmp_file.
