What php needs to know is not impetuous. 1. Syntax: you must be familiar with it. when writing code, the IDE editor should be able to report an error to a line based on the error message.
It knows what kind of syntax errors are and knows any correction.

You may have heard of Web Services for a long time, and you may already have some concepts about Web Services. For a time, it seems that all computer journals, books, and websites are beginning to mention Web Services. However, most of the current Web Service introductions do not clearly explain what the web service is. They only advocate how good web services are, just like advertising. In this article, I
ObjectiveSome problems only really encounter or use and more thinking will think, usually if as a self-study mentality to study will not consider too much, I slowly understand for those who have too much to learn or say more clearly and more specific, if you are not urgent to learn or need to master skills, Let's put it aside for a while, for example, now compare the fire of angular and react, I also took the time to learn, but the company does not need or have a special front-end you learn a lo

As an ASP. NET developer, you may be very clear about how ASP. NET handles the code in. aspx resources, how to analyze tags, and dynamically convert them to Visual BasicOr C # class. But what about next? Where do files generated by ASP. NET be stored? How can I use them to meet page requests? Since last month, I began to pay attention to this process. In this month's content, I will analyze the operations on the server, so that you can avoid some comm

and intuitive API used to query the Objects represented by the database. To modify these objects, you only need to interact with them in the program, and then tell hibernate to save the modification. Similarly, it is easy to create new objects. You only need to create them in the conventional way and then tell hibernate about them so that they can be saved in the database.
