Is there a function in php which will determine the dimensions of an image and store them in variables?

[rus321]

try something like this?

<?php
function image_mirror ($input_image_resource)
{
   $width = imagesx ( $input_image_resource );
   $height = imagesy ( $input_image_resource );
   $output_image_resource = imagecreatetruecolor ( $width, $height );
   $y = 1;

   while ( $y < $height )
   {
	   for ( $i = 1; $i <= $width; $i++ )
		   imagesetpixel ( $output_image_resource, $i, $y, imagecolorat ( $input_image_resource, ( $i ), ( $height - $y ) ) );
	   $y = $y + 1;
   }
  
   return $output_image_resource;
}
?>

That is a function to mirror the image, not get the dimensions.
Although, out of that function you would be looking specifically at:
http://php.net/manua...ion.imagesx.php
http://php.net/manua...ion.imagesy.php

And as an alternative to those, you can try the following function:
http://php.net/manua...etimagesize.php

Note: To get an images size, it has to be uploaded to a server some where where you can access it. I'm not sure if you get the the size of a temp file.
