I wish to try creating a small image converter that converts HEIC files uploaded to php web documents to .JPG (or any other common file format).

I'm running PHP on a unix server and have ImageMagick installed on the server. The following command line code is run on the server:

mogrify -format jpg *.HEIC

I want to convert this command line code to PHP.

As mentioned before, I like to convert command line formatting code to PHP. I currently have the following code set up in a basic HTML PHP form. The file being converted is newly uploaded and is not on the server. If necessary I can upload to the server first and then read from the server file.

if($_SERVER["REQUEST_METHOD"] == "POST") { if(empty($_FILES['image_url']['name'])) { echo "No File uploaded"; } else{ $uploadedImage = fopen($_FILES['image_url']['tmp_name'], 'rb'); $image_to_convert = new Imagick(); $image_to_convert->readImageFile($uploadedImage); $image_to_convert->setFormat("jpg"); $image_to_convert->setFileName('test.jpg'); header('Content-Type: image/jpg'); header('Content-disposition: attachment; filename='.$image_to_convert->getFileName()); header("Content-Description: File Transfer"); readfile($image_to_convert); } }

This code downloads the "test.jpg" file, but when I try to open it in Windows Image Viewer, it displays the "We don't seem to support this file format" message. I'm relatively new to PHP, so I don't know all the tricks of output/input streams, so if my code is bad, please let me know.

Any and all help welcome. Thanks!
