Track/detect render engine in php file..
Is there a simple php based test that I can apply to decide which browser is being used?
I have tried this code,
print_r( strtolower($_SERVER['HTTP_USER_AGENT']));
but output is,
mozilla/5.0 (x11; ubuntu; linux x86_64; rv:47.0) gecko/20100101 firefox/47.0
and I want Webkit, Safari... browser rendering engine
Please anyone can help me...
