Image Magick将文件写入文件夹

Question

I'm trying to use Image Magick to write a file to a specific location, and use uniqid() to give a unique filename (as I expect many images to be uploaded).

Heres what I have so far:

$targetdir = '/var/www/html/uploads/';
$targetfile = basename($_FILES["image"]["name"]);

move_uploaded_file($targetfile,$targetdir);

$image = new Imagick($_FILES['image']['tmp_name']);
$uid = uniqid();

$image->setImageColorspace(imagick::COLORSPACE_RGB);
$image->setImageFormat("jpeg");
$image->scaleImage(80,80);
$image->setFilename($uid);

$_FILES['image']->writeImageFile($targetdir);

The file is originally a JPEG.

I am using Ubuntu 14.04 with nescessary delegates for the images.

The error I am recieving is:

 Call to a member function writeImageFile() on a non-object

Which is using the variable $targetdir - however according to php.net documentation writeImageFile should have a target directory to write the image.

Thanks for your time

Answer 1

Try calling

$image->writeImage($targetdir.$uid.".jpg"); 

instead of

$_FILES['image']->writeImageFile($targetdir);
