Someone posted a while ago a MQL / MySQL example which worked great, the only issue with it is that most hosting companies do not allow remote access to their database servers. However if you did have full access and control to your server you would write an EA which would connect to your database and insert the data for each new order. Then from your website simply connect to the database and read the data ... In my opinion this would be the best approach.

Now a MT4 DLL can connect to a php script but I have never tried to pass the information from the EA to the Website, I was able to successfully do it the other way around though ... You would have to look into windows sockets, and functions such as HTTP_GET / HTTP_POST.
