Explore the maze of PHP operators: discover hidden treasures

php editor Yuzi takes you to explore the maze of PHP operators and helps you discover hidden treasures. PHP operators are a very important part of programming, they can help us implement various calculations and logical operations. In this maze, we will gain an in-depth understanding of the functions and usage of various operators, unlock their mysteries, and discover their hidden treasures, so that you can navigate the world of PHP programming with ease. Let's start this wonderful journey of exploration together!

• *, -, , /: ** Basic addition, subtraction, multiplication, and division operators, which can operate on integers and floating point numbers.
• %: Modulo operator, returns the remainder of division operation.
• , --: Increment and decrement operators, respectively increase or decrease the operand by 1.

Comparison Operators: Guardians of the Logical World

• ==, !=: Equality and inequality comparison operators, check whether the two operands are equal or not equal.
• <, <=, >, >=: Less than, less than or equal to, greater than, greater than or equal to comparison operators are used to compare the sizes of two operands.

Logical Operators: Navigators of the Boolean World

• &&: AND operator, returns true if both operands are true, otherwise returns false.
• ||: OR operator, returns true if either operand is true, otherwise returns false.
• !: NOT operator, inverts the Boolean value of the operand, that is, true becomes false, and false becomes true.

Assignment Operator: Engineer of the Variable World

• =: Basic assignment operator, assigns the value of the right operand to the left operand.
• * =, -=, =, /=: ** Compound assignment operator, which performs addition, subtraction, multiplication, and division operations while assigning values.

Increment and decrement operators: a blend of speed and convenience

• : Prefix increment operator, increment the operand before using it.
• =： Post-increment operator, increment the operand after using it.
• --: Prefix decrement operator, decrement the operand before using it.
• -=: Post-decrement operator, decrement the operand after using it.

Bitwise Operators: The Manipulator of the Binary World

• &: The AND bit operator performs an AND operation on each binary bit of the two operands. The result is 1 only when the corresponding bits of both operands are 1.
• |： OR bit operator performs OR operation on each binary bit of the two operands. The result is 1 only when any of the corresponding bits of the two operands is 1. .
• ^: The XOR bit operator performs an XOR operation on each binary bit of the two operands. The result is 1 only when the corresponding bits of the two operands are different.
• ~: NOT bit operator, inverts each binary bit of the operand, that is, 0 becomes 1, and 1 becomes 0.

Other Operators: Gems of Language

• .: connection operator, used to connect strings .
• ?:: The ternary operator provides a way to select values ​​based on conditional expressions.
• ::: Scope resolution operator, used to access static methods and class constants.

By exploring PHP's treasure trove of operators, we can unlock unlimited possibilities, perform complex operations, control program flow, and manipulate data. Mastering the essence of these operators will make us skilled php programmers, able to write efficient and maintainable code.
