如何在$ _FILES ['']中使用getimagesize()? [英] How can I use getimagesize() with $_FILES['']?

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;    
}
