possible to export to the string itself. This requires understanding the variable definition of PHP. Five, PHP variables Like ASP, PHP variables can be used without first defining them. For the type of the variable, it is automatically generated when the value is assigned. Various variables in PHP are preceded by the variable name with "$" to differentiate. $a = "123"; echo A; echo $a; ?> Enter as "A123" Six, single and double quotes in PHP $a = "123"; echo "$a"; echo ' $a '; ?> The outpu

Content: Calculate the number of daffodils in-999. (If the three digits are abc, abc = a ^ 3 + B ^ 3 + C ^ 3, ABC is called the number of daffodils. For example, 153,1 ^ 3 + 5 ^ 3 + 3 ^ 3 = 1 + 125 + 27 = 153, then 153 is the number of daffodils) Input description: None Output description: One integer per line # Include (Grammar question 27) daffodils

JSON{ "name" : "李狗蛋", "age" : 18, "color" : "yellow"}1、 所有的属性名，必须使用双引号包起来；2、 字面量侧重的描述对象，JSON侧重于数据传输；3、 JSON不支持undefined；4、 JSON不是对象，从服务器发来的json一般是字符串，通过JSON.parse(jsonDate.json)可以将其转换成js对象；22. JS Parsing（1）、作用域全局作用域：整个代码所有地方都可以调用；局部作用域：在函数内部声明的变量，只可以在函数内部使用；（2）、变量提升和函数提升预解析：在解析的时候，var和function都会被提升到代码的最顶端； 但是赋值操作不会被提升，定义和函数才会被提升； if里面的变量定义也会被提升，但是赋值操作不会；23.

] (if (Recur causes the program to restart the loop execution. But how to simply re-execute loops in a program is just stepping in place, because all bindings are always the initial values. So recur not only transforms the execution flow of the program, but also modifies the binding that the loop begins with . That is, recur allows loop to begin binding to a (+ 1 a).If we provide more than one binding at the beginning of the loop(Loop [a 0 B 1] (if (REPL will tell us that the number of arguments
