Syntax simple PHP starts with a weak type (it's just not that weak, it's not a strong type), and it doesn't have to be about type conversions, and even for a long time in the beginning, it doesn't support object-oriented. PHP can easily access data from the database, while half of the sites are simply reading and writing data from the database. because PHP runs as CGI or FastCGI, there is no need to consider memory mana

Now we have a simple data structure and can be saved to a file and loaded from a file page. Let's write a main to test:
func main() { p1 := Page{Title: "TestPage", Body: []byte("This is a sample Page.")} p1.save() p2, _ := loadPage("TestPage") fmt.Println(string(p2.Body))}
After compiling and running the program, a file named TestPage.txt is created with the contents of the page body that P1 contains. Th

Some unfamiliar features in C language are well known in C LanguageDesignated initializers (c99)
C99 allows you to initialize the variable specified in the struct, as shown in figure
Struct Foo {
Int x;
Int y;
Int z;
};
Foo = {. z = 3,. x = 5 };
X is initialized to 0 by default.
The specified initialization can also be applied to arrays, as shown in the following three equivalent array definitions.
Int a [5] = {[1] = 2, [4] = 5 };
Int a [] = {[1] = 2,
