[SOLVED] getimagesize

How do you actually get the dimensions of an image using getimagesize(). I do not know which variable I should be using. Here is my code

<html>
<body>
<br />
<center>
<form name="upload" action="<?php $_SERVER['PHP_SELF'] ?>" method="post" enctype="multipart/form-data">
<input type="file" name="avatar" id="avatar" maxlength="60" />
<br />
<input type="submit" name="submit" id="submit" value="Upload" />
<br />
</form>
<?php

if($_POST)
{

// set variables
$errors = 0;
$directory = 'files/';
$max_file_size = '10000';
$allowed_files = array('image/gif');
$file_location = 'avatar/';
$file_upload_name = ''.$page_id.'';
// get avatar information
$file_name = $_FILES['avatar']['name'];
$file_size = $_FILES['avatar']['size'];
$file_type = $_FILES['avatar']['type'];
$file_dim = getimagesize(???); // what goes here ?

echo "name = ".$file_name."<br />";
echo "size = ".$file_size."<br />";
echo "type = ".$file_type."<br />";
echo "dim = ".$file_dim."<br />";

if(empty($file_size) or empty($file_name) or empty($file_type))
{
} else
{
list($blank,$file_extension) = explode('image/',$file_type);

if($file_size > $max_file_size)
{
	echo "Your file is larger than 10kb.<br />";
	$errors++;
}
if(!in_array($file_type, $allowed_files))
    {
	echo "You are not allowed to upload that file type.<br />You are only allowed: .gif<br />";
	$errors++;
    }
if($errors == 0)
{
	copy($_FILES['avatar']['tmp_name'], "files/".$_FILES['avatar']['name']) or die ("Could not copy");
	echo "Your image has been uploaded";
} else
	if($errors > 0)
	{
		$errors = 0;
		die("");
	}
}

}

?>
</body>
</html>

Try the following:

<?php
// Get the details of the image
list($width, $height, $type, $html_string, $mime) = getimagesize($_FILES['avatar']['tmp_name']);

// Print out the width and height
echo "Width: $width<br>\n";
echo "Height: $height<br>\n";
?>

Or alternatively, get all the information and list it like so

<?php
// Get the details of the image
$image_details = getimagesize($_FILES['avatar']['tmp_name']);

// Print out all information
foreach ($image_details as $v){
   echo "$v<br>\n";
}
?>

This will be ordered as follows... Width, Height, type of image, html string to use in <img> tags, mime type.

But I prefer the first method.
