Best sites/resources to learn about PHP

[SanjayRocks]

Hi,


Can anyone recommend me the best youtube channels/tutorial web sites to learn PHP.
Also any good book to buy so can read it when travelling.

Also if someone like to have a career in PHP development what other skills he needs to learn. What are the most demanding skills in 2015/2016. eg: HTML5, CSS, Java Scripts ???

Thank you for all the replies
