Windows Usage

After a lot of test, I finally succeeded to decode work.

Here's the solution
$decoder = new \PHPZxing\PHPZxingDecoder();
// Set java path with double quote '"path/to/java/exe"'
$decoder->setJavaPath('"C:\Program Files\Java\jdk1.8.0_202\bin\java.exe"');
// replace \ by / in file path
$newPath=str_replace('\','/',$tmpfilePath);
// add file:/// before file Path
$data = $decoder->decode('file:///'.$newPath);
