[php-src] Issue #10351: imageresolution Return incorrect DPI

Issue: https://github.com/php/php-src/issues/10351 Author: ve3 ### Description The following code: ```php <?php $fullPathNewFileName = '772.jpg'; $img = imagecreatefromjpeg($fullPathNewFileName); $result = imageresolution($img); var_dump($result); ``` Resulted in this output: ``` array(96, 96) ``` But I expected this output instead: ``` array(240, 240) ``` You may test with this jpeg file in zip. https://gofile.io/d/IiGLN1 Not all images are detected DPI correctly. Only some images are unable to detect and return 96 DPI. This happens since PHP 7 or older but PHP 8.2 still occur. If I use Imagick on PHP 8.1 or any version, it returns correct resolution. ```php $Img = new Imagick($fullPathNewFileName); $result = $Img->getImageResolution(); var_dump($result);// array('x' => 240, 'y' => 240) ``` ### PHP Version PHP 8.2.0 ### Operating System Windows 11 x64
