php resize image on upload

Question

I got a form where the user is inserting some data and also uploading an image.

To deal with the image, I got the following code:

define(\"MAX_SIZE\"

If you want to use Imagick out of the box (included with most PHP distributions), it's as easy as...

$image = new Imagick();
$image_filehandle = fopen('some/file.jpg', 'a+');
$image->readImageFile($image_filehandle);

$image->scaleImage(100,200,FALSE);

$image_icon_filehandle = fopen('some/file-icon.jpg', 'a+');
$image->writeImageFile($image_icon_filehandle);

You will probably want to calculate width and height more dynamically based on the original image. You can get an image's current width and height, using the above example, with $image->getImageHeight(); and $image->getImageWidth();
