In the brother Lian training, this half month in a project, during the period of learning a lot of things, but there are many have not learned to use flexibly. Today in the login interface to add the verification code, the form submitted does not pass the verification code in input, the session does not pass the verification code image displayed on the value (the GD library write verification code function). There is a front-end user to change personal information occasionally will make a small error, and then after debugging to complete the normal function, may be writing database query statements when the logic of the problem. There is the biggest problem is the background management, written out of the operation is basically in the database of additions and deletions to check, these statements a lot of chaos. Often this statement is useful, and the other is not good. This is a big problem! However, in general, I have my own foreach traversal, SQL statements, key speed improvement is still very satisfied, after all, is a just starting small white. Through the eight days of learning to learn a lot of things. I feel like I'm starting to love PHP.
