The getimagesize() function is used to obtain the dimensions and file type of an image. It takes the path of the image file as a parameter and returns an array containing the width, height, type, and MIME type of the image.

Here is a basic example:

$filename = 'path/to/your/image.jpg';
$imagesize = getimagesize($filename);

echo 'Image width: ' . $imagesize[0] . 'px<br>';
echo 'Image height: ' . $imagesize[1] . 'px<br>';
echo 'Image type: ' . $imagesize[2] . '<br>';
echo 'MIME type: ' . $imagesize['mime'];

注意：The getimagesize() function can only be used to read local files and cannot be used to read remote files.
