get photo from folder then get its size

[proctk]

probably an easy question.  I now the file name (assigned to variable) of a file saved in a folder "user_images" I want to get the image size and assign the values to variables.

The manual comes in handy....getimagesize().

I use this, but don't use if you don't understand (its about the learning)

<?php
	$image = "";
	$tempimg = getImageSize($image);
	$size = $tempimg[3];
	$size = explode("\"",$size);
	$width = $size[1];
	$height = $size[3];
?>
