Description:
------------
I am using the code below. in php 8.0 is_resource returns false on this code.

I can rewrite that code of course but i want to understand why it now suddenly does not work anymore.

Is this a bug or is this caused by the changes made in php 8.0?

Please advice 

Thank you !

Test script:
---------------
$file=  '/var/public/wp-content/uploads/2020/11/image_001.jpg';
$image = imagecreatefromstring( file_get_contents( $file ) );

if ( !is_resource( $image ) )
	return new WP_Error( 'error_loading_image', $image, $file );

This is intended. In php 8.0 a lot of resource has been converted into objects. see https://github.com/php/php-tasks/issues/6, and https://github.com/php/php-src/pull/4714 for your case.

Instead of

    if ( !is_resource( $image ) )

use

    if ( $image === false )

for compatibility with "all" PHP versions.
