PHP从file_get_contents获取图像尺寸（“php：// input”）

Question

Due to the upload script I can not obtain the uploaded file by $_FILE variable, thefore I have to make do with

$file = file_get_contents("php://input")

I want to get the dimensions if it's an image, for that purpose, I would use getimageresize() but getimageresize() only take a file not a string. So that's my problem. How do i solve this?

Answer 1

$image = imagecreatefromstring($img_str);
$w = imagesx($image);
$h = imagesy($image);
