Study Notes
Introduction to Web Development
- PHP is a widely used scripting language designed for web development.
- Operators in PHP perform operations on variables or values.
PHP Operators
- Types of PHP Operators include:
- Arithmetic Operators: Perform basic mathematical operations.
- String Operators: Used to concatenate strings.
- Assignment Operators: Assign values to variables.
- Array Operators: Manage arrays.
- Bitwise Operators: Perform operations on binary numbers.
- Type Operators: Used for type checking.
- Comparison Operators: Compare values.
- Execution Operators: Execute external programs.
- Incrementing/Decrementing Operators: Increment or decrement variables.
- Error Control Operators: Suppress error messages.
Categorization of Operators by Operands
- Unary Operators: Operate on a single operand; examples include increment (++) and decrement (--).
- Binary Operators: Operate on two operands; typical examples are addition (+), subtraction (-), and multiplication (*).
- Ternary Operators: Operate on three operands; example includes the ternary conditional operator (?:).
PHP Arithmetic Operators
- Used for performing calculations:
- Addition (+): Combines two numbers.
- Subtraction (-): Finds the difference between numbers.
- Multiplication (*): Calculates the product.
- Division (/): Computes the quotient.
- Modulus (%): Returns the remainder of division.
- Exponentiation ()**: Raises a number to the power of another.
PHP Assignment Operators
- Facilitate assigning values to variables efficiently:
- Basic Assignment (=): Assigns the value of the right operand to the left.
- Add then Assign (+=): Adds right operand to left operand and assigns the result.
- Subtract then Assign (-=): Subtracts right operand from left operand and assigns the result.
- Multiply then Assign (*=): Multiplies operands and assigns the product.
- Divide then Assign (/=): Divides left operand by the right and assigns the quotient.
- Modulus Assignment (%=): Assigns the remainder of division between operands.
PHP Comparison Operators
- Used to compare two values for equality or difference:
- Equal (==): Returns TRUE if values are equal.
- Identical (===): Returns TRUE if values are equal and of the same type.
- Not Identical (!==): Returns TRUE if values are not equal or not of the same type.
- Not equal (!=): Returns TRUE if values are not equal.
- Less than (<): Returns TRUE if left operand is smaller.
- Greater than (>): Returns TRUE if left operand is larger.
Control Structures
- Control structures such as IF and SWITCH statements are critical for handling program logic and flow.
