What are some best practices for efficiently handling image size determination in PHP?

When handling image size determination in PHP, it is important to efficiently check the dimensions of the image to ensure it meets specific requirements. One way to achieve this is by using the getimagesize() function in PHP, which returns an array containing the width and height of the image. By using this function, you can easily determine the size of the image and make decisions based on those dimensions. 

// Get the dimensions of the image
$image_info = getimagesize('image.jpg');
$image_width = $image_info[0];
$image_height = $image_info[1];

// Check if the image meets specific requirements
if ($image_width >= 800 && $image_height >= 600) {
    echo 'Image size is sufficient.';
} else {
    echo 'Image size is not sufficient.';
}
