问题描述
我正在做一个图像上传处理器,我希望它可以检测用户上传的图像的尺寸.
I am doing an image upload handler and I would like it to detect the dimensions of the image that's been uploaded by the user.
所以我开始:
if (isset($_FILES['image'])) etc....
我有
list($width, $height) = getimagesize(...);
我应该如何一起使用它们?
How am i supposed to use them together?
非常感谢
推荐答案
您可以这样做
$filename = $_FILES['image']['tmp_name'];
$size = getimagesize($filename);
// or
list($width, $height) = getimagesize($filename);
// USAGE: echo $width; echo $height;
结合使用条件,这是一个示例
Using the condition combined, here is an example
if (isset($_FILES['image'])) {
$filename = $_FILES['image']['tmp_name'];
list($width, $height) = getimagesize($filename);
echo $width;
echo $height;
}
