Simple syntax rules (use curly braces to define variable names for all versions of PHP): $a = ' flower '; echo "She received some $as"; The letter S will be considered as a valid variable name, but here the variable is a $ A echo "She received some ${a}s"; Effective echo "She received some {$a}s"; Effective; Recommended
First of all, the use of braces {} to include the data, which means that the data of the array of data, not equivalent to the general data, such as: {"A", "B", "C"} is the data of the array.
Let me introduce you to the use example of the braces {} data.
Look at the table first.
In the table, look at the
talk about the use of {} curly braces and [] brackets in JS, and then you can understand the JSON structure. A, {} curly brace, which means defining an object, in most cases a pair of properties and values, or a function. for example: var = {"Name": "Langshen", "Age": "Langshen"};an object named "Langshen" is declared above, with multiple properties or functions separated by, (comma), because it is the prop
{} curly braces, which means defining an object, in most cases having a pair of properties and values, or a functionFor example: var langshen = {"Name": "Langshen", "Age": "28"};An object named "Langshen" is declared above, with multiple properties or functions separated by, (comma), because it is the property of the object,So when you visit, you should use. (point) to layer access: Langshen.name, Langshen.
{} curly braces, which means defining an object, in most cases having a pair of properties and values, or a functionA, {} curly brace, which means defining an object, in most cases a pair of properties and values, or a function.For example: var langshen = {"Name": "Langshen", "Age": "28"};An object named "Langshen" is declared above, with multiple properties or functions separated by, (comma), because it is the property of the object,So when you visit
object, so it equals: var Langshen = Array ("Name", "Langshen", "Age", "28"); When accessed, it is also an array of alert (langshen[0]);Three, {} and [] with, as we said before, {} is an object, [] is an array, we can make up an array of objects, such as:var langshen = {"Name": "Langshen","MyWife": ["LuLu", "26"],"Myson": [{"Name": "Son1"},{"name": "Son2"},{"name": "Son3"}]}From the structure above, the first item inside an object is a property, the second item is an array, and the third is an
Let's talk about the use of {} braces and [] brackets in JS. After understanding them, we can understand the JSON structure.
1. braces {} indicate defining an object. In most cases, there must be a pair of attributes and values or functions.For example, VAR langshen = {"name": "langshen", "Age": "28 "};The above declares an object named "langshen". multi
In C #, String. format is a very convenient string format method.
For example, to output the sentence "Bill is a student.", you can use the following method:String studentname = "bill ";String. Format ("{0} is a student.", studentname );
In this way, you can dynamically format the string.
It can be found that braces are used to format strings. That is to say, if you want to format
