Operators
Logical operators in programming are like a set of tools that help us decide what to do depending on how things look. Logical operators tell the computer to do something based on how two different things compare.


Addition ^{Arithmetic Operators}

The addition operator returns the sum of two variables.
Php
Example of addition operator in php.
<?php $age = 20; print($age + 1); // 21



Subtraction ^{Arithmetic Operators}

The subtraction operator returns the difference of two variables.
Php
Example of subtraction operator in php.
<?php $age = 20; print($age  2); // 18



Multiplication ^{Arithmetic Operators}

The multiplication operator returns the product of two variables.
Php
Example of multiplication operator in php.
<?php $age = 20; print($age * 3); // 60



Division ^{Arithmetic Operators}

The division operator returns the quotient of two variables.
Php
Example of division operator in php.
<?php $age = 20; print($age / 2); // 10



Modulus ^{Arithmetic Operators}

The modulus operator returns the remainder of two variables.
Php
Example of modulus operator in php.
<?php $age = 20; print($age % 9); // 2



Exponentiation ^{Arithmetic Operators}

The exponentiation operator returns the power of two variables.
Php
Example of exponentiation operator in php.
<?php $age = 2; print($age ** 3); // 8



Equal ^{Comparison Operators}

The equal operator checks if two variables are equal value.
Php
Example of equal operator in php.
<?php $age = 20; print($age == 20); // true



Equal Type ^{Comparison Operators}

The equal type operator checks if two variables are equal value and type.
Php
Example of equal type operator in php.
<?php $age = '20'; print($age === '20'); // true



Not Equal ^{Comparison Operators}

The notequal operator checks if two variables are not equal value.
Php
Example of notequal operator in php.
<?php $age = 20; print($age != 18); // true



Not Equal Type ^{Comparison Operators}

The notequal type operator checks if two variables are not equal value and type.
Php
Example of notequal type operator in php.
<?php $age = 20; print($age !== '20'); // true



Greater Than ^{Comparison Operators}

The greaterthan operator checks if the value of the first variable is greater than the second.
Php
Example of greaterthan operator in php.
<?php $age = 20; print($age > 18); // true



Less Than ^{Comparison Operators}

The lessthan operator checks if the value of the first variable is less than the second.
Php
Example of lessthan operator in php.
<?php $age = 20; print($age < 21); // true



Greater Than or Equal ^{Comparison Operators}

The greaterthan or equalto operator checks if the value of the first variable is greater than or equal to the second.
Php
Example of greaterthan or equalto operator in php.
<?php $age = 20; print($age >= 20); // true



Less Than or Equal ^{Comparison Operators}

The lessthan or equalto operator checks if the value of the first variable is less than or equal to the second.
Php
Example of lessthan or equalto operator in php.
<?php $age = 20; print($age <= 20); // true
