How can the PHP version on the server affect the functionality of getimagesize()?

The PHP version on the server can affect the functionality of getimagesize() because the behavior and supported image types may vary between different PHP versions. To ensure compatibility and consistent results, it is recommended to use a PHP version that supports the image types you are working with. If you encounter issues with getimagesize(), consider updating your PHP version to a more recent release. 

// Check the PHP version before using getimagesize()
if (version_compare(PHP_VERSION, '7.2.0') >= 0) {
    $imageInfo = getimagesize('image.jpg');
    // Use the image information as needed
} else {
    echo 'PHP version 7.2.0 or higher is required for getimagesize()';
}
