Are there any best practices for efficiently determining the dimensions of an image in PHP?

When working with images in PHP, it is important to efficiently determine the dimensions of an image. One common 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 retrieve the dimensions of an image without having to load the entire image into memory. 

// Get the dimensions of an image using getimagesize()
$imagePath = 'path/to/your/image.jpg';
$dimensions = getimagesize($imagePath);

$width = $dimensions[0];
$height = $dimensions[1];

echo "Width: $width, Height: $height";
