What are some best practices for retrieving image size information using PHP?

When working with images in PHP, it is important to retrieve their size information to properly handle and display them on a website. One way to do this is by using the getimagesize() function in PHP, which returns an array containing the width and height of the image, as well as other information like the image type and attributes. 

// Get the size information of an image
$imagePath = 'path/to/your/image.jpg';
$sizeInfo = getimagesize($imagePath);

// Output the width and height of the image
$imageWidth = $sizeInfo[0];
$imageHeight = $sizeInfo[1];

echo "Image width: " . $imageWidth . "px<br>";
echo "Image height: " . $imageHeight . "px";
