I wanna learn the php skill by myself. But I found that is difficult. So would pls give me some suggestions on teaching video? Thank you very much!

If you want to learn PHP at home you can learn from W3school. You can clear your basic concept from them and learn php. You need not to do any tuition classes for that. This is freely available on internet, the practice examples are also given over there. For more guidance you can ask us.
