Arithmetic Operators in PHP Language

Arithmetic operators are used for mathematical calculations. PHP supports the following arithmetic operators:

• Addition (+): Adds two values together. Example:

  $sum = 10 + 5; // $sum now holds 15

• Subtraction (-): Subtracts the second value from the first. Example:

  $difference = 20 - 8; // $difference now holds 12

• Multiplication (*): Multiplies two values. Example:

  $product = 6 * 4; // $product now holds 24

• Division (/): Divides the first value by the second. Example:

  $quotient = 50 / 10; // $quotient now holds 5

• Modulus (%): Returns the remainder of the division. Example:

  $remainder = 17 % 5; // $remainder now holds 2

Assignment Operators in PHP Language

Assignment operators are used to assign values to variables. PHP supports various assignment operators, with the most basic being the equal sign (=).

Example:

$x = 10; // $x is assigned the value 10

Comparison Operators in PHP Language

Comparison operators are used to compare values and return either true or false. PHP supports the following comparison operators:

• Equal (==): Checks if two values are equal. Example:

  $result = (5 == 5); // $result is true

• Not Equal (!=): Checks if two values are not equal. Example:

  $result = (8 != 5); // $result is true

• Identical (===): Checks if two values are equal and of the same data type. Example:

  $result = (5 === "5"); // $result is false

• Not Identical (!==): Checks if two values are not equal or not of the same data type. Example:

  $result = (5 !== "5"); // $result is true

• Greater Than (>): Checks if the first value is greater than the second. Example:

  $result = (10 > 5); // $result is true

• Less Than (<): Checks if the first value is less than the second. Example:

  $result = (5 < 10); // $result is true

Logical Operators in PHP Language

Logical operators are used to perform logical operations. PHP supports the following logical operators:

• And (&&): Returns true if both conditions are true. Example:

  $result = (true && true); // $result is true

• Or (||): Returns true if at least one of the conditions is true. Example:

  $result = (true || false); // $result is true

• Not (!): Returns the opposite of the condition. Example:

  $result = !true; // $result is false

Increment and Decrement Operators in PHP Language

Increment and decrement operators are used to increase or decrease the value of a variable by 1.

• Increment (++$x): Increases the value of $x by 1. Example:

  $x = 5;
  ++$x; // $x is now 6

• Decrement (–$x): Decreases the value of $x by 1. Example:

  $x = 5;
  --$x; // $x is now 4

Concatenation Operator in PHP Language

The concatenation operator (.) is used to combine strings.

Example:

$greeting = "Hello, ";
$name = "John";
$message = $greeting . $name; // $message now holds "Hello, John"

Conditional (Ternary) Operator in PHP Language

The conditional operator (often referred to as the ternary operator) is a shorthand way to write simple if-else statements.

Example:

$age = 18;
$status = ($age >= 18) ? "Adult" : "Minor";
