PHP - Get Mov Dimensions

This interface was created by dissecting the photo that you see into 20 pieces, and floating them to the left within a container.   I would like to know if I could individually scale the pieces together, with the same multiplying factor after the multiplying factor has been determined from the device's screen resolution.     fix.jpg   81.35KB   0 downloads

Here is my dilemma and thank you in advance!

I am trying to create a variable variable or something of the sort for a dynamic associative array and having a hell of a time figuring out how to do this. I am creating a file explorer so I am using the directories as the keys in the array.

Example:
I need to get this so I can assign it values

$dir_list['root']['folder1']['folder2'] = value;

so I was thinking of doing something along these lines...

if ( $handle2 = @opendir( $theDir.'/'.$file ))
{
    $tmp_dir_url = explode($theDir);
    for ( $k = 1; $k < sizeof ( $tmp_dir_url ); $k++ )
    {
        $dir_list [ $dir_array [ sizeof ( $dir_array ) - 1 ] ][$tmp_dir_url[$k]]
    }

this is where I get stuck, I need to dynamically append a new dimension to the array durring each iteration through the for loop...but i have NO CLUE how

Do I need to check both the "Image Size" AND "Image Dimensions" for files that Users upload to my website?

Currently I have...

// ********************
// Check File-Size. *
// ********************
if (empty($errors)){
// Check File-Size in Bytes.
if (filesize($tempFile)<4000){
// File too small.
$errors['upload'] = 'File-size must be greater than 4 Kilobytes.';
}elseif (filesize($tempFile)>100000){
// File too big.
$errors['upload'] = 'File-size must be less than 100 Kilobytes.';
}else{
// File-Size Okay.
// Continue Processing Upload...
}
}//End of CHECK FILE-SIZE



I guess I haven't been worrying about "File Dimensions" because I resize everything here...

// **********************
// Set New Dimensions. *
// **********************

// Capture Dimensions on Original Image.
$origWidth = imageSX($origImage);
$origHeight = imageSY($origImage);

if ($origWidth > $origHeight){
$newWidth = 100;
$multiplier = $newWidth/$origWidth;
$newHeight = $origHeight * $multiplier;
}

if ($origWidth < $origHeight){
$newHeight = 100;
$multiplier = $newHeight/$origHeight;
$newWidth = $origWidth * $multiplier;
}

if ($origWidth == $origHeight){
$newWidth = 100;
$newHeight = 100;
}


Thanks,
