由mikehaertl安装phpwkhtmltopdf

I've spent hours on this problem and still got nothing. I'm quite a noob when it comes to installing something rather than double clicking may that's why i'm stuck.

What i want to do is to develop a web service which takes a url and returns an image file of the screen shot of that url. I found out that i can do this doing the following steps:

  1. Using wkhtmltopdf to convert my html files to pdf
  2. And then converting this pdf to image using php imagic library.

I'm still on the first step. I downloaded an executable for wkhtmltopdf from some website and by using the following lines in command line, i successfully created a pdf:

\"C:\\Program Files\\wkhtmltopdf\\bin\\wkhtmltopdf\" --page-width 300 --page-height 225 \"$url\"    $dir\\$tempName.pdf &

But now i wanted to make this as a web service online but this lines just run on cmd, not on a shared hosting server. What to do know? I've also seen phpwkhtmltopdf but i don't understand the installation phase as disscused Here.
