Describe the bug

In a customer's site we face the following error:

[23-May-2024 08:15:14 UTC] PHP Fatal error:  Uncaught TypeError: strpos() expects parameter 1 to be string, int given in /home/customer/www/staging2.xxx.com/public_html/wp-content/plugins/imagify/classes/Optimization/Process/AbstractProcess.php:1641
Stack trace:
#0 /home/customer/www/staging2.xxx.com/public_html/wp-content/plugins/imagify/classes/Optimization/Process/AbstractProcess.php(1641): strpos(200, '@imagify-webp')
#1 [internal function]: Imagify\Optimization\Process\AbstractProcess->Imagify\Optimization\Process\{closure}(200)
#2 /home/customer/www/staging2.xxx.com/public_html/wp-content/plugins/imagify/classes/Optimization/Process/AbstractProcess.php(1642): array_filter(Array, Object(Closure))

and this happens exactly here:

https://github.com/wp-media/imagify-plugin/blob/a5b782019155e99326c7fddf1b031750b0c50c82/classes/Optimization/Process/AbstractProcess.php#L1641

In the PR (#877) we fixed similar issue when the image size name is not integer, but we once the image is optimized we save the sizes in the attachment metas to be grabbed later on the mentioned line (as far as I understand) but in php if the array has numeric keys even if u added them as strings, this will be cast to be integer then it throws the previously mentioned fatal error.

To Reproduce Steps to reproduce the behavior:

1. Add the following snippet

   add_action( 'after_setup_theme', function() {
   add_image_size( '200', 200, 200 );
   } );

2. Optimize any image and wait till it's optimized for this new size.
3. Open any post and choose the featured image
4. once media modal is opened, fatal error should be thrown and images not loaded in the modal.

Expected behavior Images should load without a problem.

I fixed this by casting the $key variable here:

Another relevant ticket with proposed solution https://secure.helpscout.net/conversation/2680413623/507765?folderId=676697

My hosting support was able to determine the issue. It seems that the Imagify plugin is not fully compatible with your version of the WordPress core and/or PHP 8.2. The Wordpress error dump identified line 1641 in /home/cypresspainting/www/www/wp-content/plugins/imagify/classes/Optimization/Process/AbstractProcess.php. They did come up with a fix for this problem Replaced return strpos( $key, $this->format ) === false; with this: return is_string($key) && strpos( $key, $this->format ) === false;
