Using the Google Searchbyimage on my website

I want to use the google searchbyimage tool on my website. On the website I want upload an picture and show all websites where this image is.

Everything like this (and no, I don't like to use this as a iframe) on my website:

 http://www.images.google.com/imghp?sbi=1&gws_rd=ssl

Found this line here:

curl -s -F "image_url=" -F "image_content=" -F "filename=" -F "h1=en"  -F "bih=179" -F "biw=1600" -F "encoded_image=@my_image_file.jpg" https://www.google.co.in/searchbyimage/upload

Is it possible in PHP or JavaScript?
