How to deal with it

For advice
I am now learning to use MySQL in conjunction with PHP development database, but do not know where to start, the first should learn what, please advise!
Thank you!

------Solution--------------------
If you do not have SQL statements, such as: Select,insert,update,delete, it is recommended that you learn the database first.
Learn the basic operation of the database and some knowledge about the concurrency of the Database learning PHP, which is very helpful to PHP.
I do not know your website how to learn the foreground:
Before you learn PHP, your personal recommendation is: PHP, HMTL, CSS, JavaScript----MySQL (also SQL statement).

Html,css,javascript is mainly used to do the front page, some people will ask, since I am learning PHP, do is the background program, why should learn the foreground production? Besides, the big company for the front desk, backstage, art, etc. do not have a clear division of labor, but also with me to write? Yes, but it's a big company, and for a small company it's all done by one person. From the page design, page layout, art, and then to the background processing is a person or several people to complete, no clear division of labor. Must be the front desk, backstage will. In large companies, although there is a clear division of labor, the front desk of these things although not required you to write, but you have to see understand.

MySQL to master is the SQL statement, is nothing more than to increase, delete, the, check, and database optimization, these are relatively simple, learn faster, but also must be mastered knowledge.

As for ajax,jquery this knowledge, when your PHP learning to a certain extent, you can consider to learn these, because in many large projects have to use Ajax, especially chat rooms.
