How can PHP developers ensure that remote image sizes are accurately determined and handled in their applications?

When working with remote images in PHP applications, developers can ensure accurate determination and handling of image sizes by using the getimagesize() function to retrieve image dimensions. This function returns an array containing the width and height of the image, which can then be used to resize or display the image appropriately in the application. 

// URL of the remote image
$image_url = 'https://example.com/image.jpg';

// Get the image size
$image_size = getimagesize($image_url);

// Output the width and height of the image
echo 'Width: ' . $image_size[0] . ' pixels<br>';
echo 'Height: ' . $image_size[1] . ' pixels';
