Tips on using the front-end code artifact Emmet

Introduction to PHP: Why should you learn it? What can PHP do?

What is the basic syntax of PHP? Tags, annotations, etc.

Introduction to PHP data types: Quickly preview and understand the basic methods of type conversion

Boolean type Boolean: the simplest and most useful type

Integer type: seemingly simple but actually very meaningful

Float: Why can't it be used directly for comparison?

String: Flexible little fairy

Array (1): Quick preview of the soundtrack version

Array (2): Index array and associative array

Array (3): add/update/delete/view

Array (4): Introduction to array traversal and common output statements

Object (1): Creation and access of objects

Object type Object (2): Use and type conversion of stdClass standard class

Variable creation and naming rules: Do not give random names

Default value of variables: Default is not the best, so initialization is required

Assignment of variables: The difference between passing by value and passing by reference

Mutable variables: Provides a new idea for creating new variables

The scope of a variable: it is the effective scope or visible scope

Predefined variables (1): $GLOBALS/$_SERVER/$_GET/$_POST

Predefined variables (2): $_COOKIE little dessert on the browser

Predefined variables (3): $_SESSION, creating a more secure session mechanism

Conditional judgment structure: double branch process of if statement

Multi-branch structure: Detailed explanation of the usage of switch statement

for loop statement: It may be a universal loop, haha

while loop: executed only when the condition is true, or may never be executed

do~while loop: it must be executed once no matter what

Operators (1): arithmetic operators, string operators, assignment operators

Operators (2): comparison operators and logical operators

Introduction to expressions: Anything with a value can be called an expression

First experience with functions and syntax details: how to create and call functions

Four parameter types of functions: value parameters/reference parameters/default parameters/variable parameters

Variable function and callback implementation: the callback function is an elf

Using callbacks to call methods of objects or classes (optional content)

Function import and file inclusion: use of include and require

Implementation of anonymous functions and closures: the principles of function expressions and closures

Secrets of function creation and calling: I won’t tell you about it for ordinary people

Definition and classification of arrays: Array elements are composed of keys and values

Array creation and access: 3 creation methods and 2 access methods

Using for loops to traverse arrays: indexing and associative arrays

Iterating through arrays using while loops: indexing and associative arrays

Using foreach loop to traverse: index and associative array

List structure: Convert elements of the default index array into variables

Use each() function to split the array elements into two representations: index and association for traversal

Use the list() structure and each() to complete the array traversal operation: must master

Get the values ​​of all elements in an array and return them in a default index array: array_values()

Get the key names of all elements and return them in the default index array: array_keys()

Check whether a key exists in the array: array_key_exists()

Check whether a value exists in the array: in_array()

Array statistical functions: count(), array_count_values() and array_unique()

Array filter array_filter(): callback function to process arrays

Array patroller array_walk(): uses callback function to traverse or update the array

Array mapper array_map(): Want to process multiple arrays at the same time? i can do it

Array sorting by value: sort() forward and rsort() reverse sorting functions

Array sorting by key name: ksort() ascending order and krsort() descending order function

Keep the key-value correspondence unchanged when sorting the array: asrot() and arsort() functions

To sort multiple arrays at the same time, the multi-dimensional array is first converted into a one-dimensional array by value: array_multisort()

Use arrays to implement stack operations: array_push and array_pop

Using arrays to implement queue operations: array_shift() and array_unshift() functions

Other array functions: array_rand()/array_sum()/shuffle()/range()

A quick introduction to object-oriented programming in PHP: the relationship between classes and objects

How to create a class and its properties and methods: naming conventions/access controls/pseudo variables

6 ways to create objects: Only using [new class name] is not a real PHP programmer

Creation and access of class constants: pay attention to the differences and connections with static properties

Class automatic loading technology: __autoload() and spl_autoload_register()

Class constructor and destructor methods: __construct() and __destruct()

Object encapsulation [not just security]: private, __get, __set, __isset, __unset

Class inheritance and polymorphism: extends and method overriding

Tips for creating and accessing static members in classes: static

Static binding and delayed binding technology of classes: detailed explanation of self, parent, static

Object cloning technology: Create new objects like variable value transfer

What should I do if I access a non-existent method or static method? Detailed explanation of __call() and __callSatatic()

Serialization of objects: a method of transmitting or saving an object

Abstract methods and abstract classes: templates for user classes

Implementation of interface technology: standardizing members and types of user classes

Declaration and usage skills of trait characteristics: Collection of class methods to achieve code reuse

Namespace: Although we have the same name and the same sex, we belong to different time and space

Object traversal: View object properties just like traversing an array

PHP5.6 extension to namespace: use can import functions and constant spaces
