A few days ago, in order to solve sinpool's multi-thread problem, I read the source code of tomcat 4.1.30,

PHP code for displaying the date and time. PHP's display time code is much more powerful than ASP, making it easier to call. 1. year-month-day echodate (Y-m-j); 2012-02-6echodate (y-n-j ); 07-2-6 capital Y indicates that the code for displaying the time of the four-digit PHP in a year is much more powerful than that of ASP, making it easier to call.

I haven't pasted the complete code for a long time before the introduction in section 15th. In fact, I think the first 14 sections are basic things. Let's first recall what we learned. At the beginning, I mainly wanted to let everyone understand tomcat as a combination of ctor and container. Later, we know that ctor Ctor is used to establish a connection. We talked about tomcat4's default connector, although it is replaced now. The Container is used t

In this article, we need to understand a problem. We know that a linker is associated with a container, and when is the container associated with the linker?Before you understand this problem, you should first understand the Digester library, which simply resolves xml files. There are two concepts: Patterns and rules. The so-called schema is an xml tag, the rule is what an xml tag needs to do.
