回答1:

 $data = getimagesize($filename);
 $width = $data[0];
 $height = $data[1];

Through Intervention Image you can do it as

$upload_file = $request->file('gallery_image');
$height = Image::make($upload_file)->height();
$width = Image::make($upload_file)->width();

You can use

 <?php
$imagedetails = getimagesize($_FILES['file-vi']['tmp_name']);

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

?>
