PhantomJs is the solution
if(phantom.state.length === 0){
phantom.state = '0_home';
phantom.open('http://www.mini.de');
}
else if(phantom.state === '0_home'){
phantom.viewportSize = {width: 800, height: 600};
phantom.sleep(2000);
phantom.render('home.png');
phantom.exit(0);
}

CutyCapt is a small cross-platform command-line utility to capture WebKit's rendering of a web page into a variety of vector and bitmap formats, including SVG, PDF, PS, PNG, JPEG, TIFF, GIF, and BMP.
There is no PHP-api, but you can always use it through PHP's exec
functions.
Here is a better script using phantomJS 1.5
var page = require('webpage').create();
page.open('http://www.google.com', function() {
page.viewportSize = {width: 1024, height: 768};
page.render('screenshot.png');
phantom.exit();
});
