The key concepts of program structure in C # Are program, namespace, type, member, and assembly. C # The program contains one or more source files. Declared type in the program. The type contains members and can be organized into the namespace. Class and interface are examples of types. Fields, methods, attributes, and events are member examples. When C # programs are compiled, they are physically packaged into the assembly. The file extension name of the program set is generally .exe or. dll, d
organized as its users and complexity grow.
"Hello Symfony2" page
Let's start with the classic "hello, world" program. after we finish, you can get a greeting by visiting the following URL:
http://localhost/app_dev.php/hello/Symfony
In fact, you can replace Symfony with another name to greet you. to create this page, we just need to perform the following two steps:
This tutorial assumes that you have downloaded Symfony2 and configured the Web server. The above URL assumes that localhost point
