• # 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.

• ## Increment Operators

• The increment operator increments the value of a single variable.

• #### Php

##### Example of increment operator in php.
``````<?php
\$age = 20;

// Increment After
print(\$age++); // 20
print(\$age); // 21

// Increment Before
print(++\$age); // 22
print(\$age); // 22``````
• ## Decrement Operators

• The decrement operator decrements the value of a single variable.

• #### Php

##### Example of decrement operator in php.
``````<?php
\$age = 20;

// Decrement After
print(\$age--); // 20
print(\$age); // 19

// Decrement Before
print(--\$age); // 18
print(\$age); // 18``````

• 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
``````
• ## Addition Assignment Arithmetic Operators

• The addition assignment operator returns the sum of two counterparts.

• #### Php

##### Example of addition assignment operator in php.
``````<?php
\$age = 20;

\$age += 1;

print(\$age); // 21
``````
• ## Subtraction Assignment Arithmetic Operators

• The subtraction assignment operator returns the difference of two counterparts.

• #### Php

##### Example of subtraction assignment operator in php.
``````<?php
\$age = 20;

\$age -= 2;

print(\$age); // 18
``````
• ## Multiplication Assignment Arithmetic Operators

• The multiplication assignment operator returns the product of two counterparts.

• #### Php

##### Example of multiplication assignment operator in php.
``````<?php
\$age = 20;

\$age *= 3;

print(\$age); // 60
``````
• ## Division Assignment Arithmetic Operators

• The division assignment operator returns the quotient of two counterparts.

• #### Php

##### Example of division assignment operator in php.
``````<?php
\$age = 20;

\$age /= 2;

print(\$age); // 10``````
• ## Modulus Assignment Arithmetic Operators

• The modulus assignment operator returns the remainder of two counterparts.

• #### Php

##### Example of modulus assignment operator in php.
``````<?php
\$age = 20;

\$age %= 9;

print(\$age); // 2
``````
• ## Exponentiation Assignment Arithmetic Operators

• The exponentiation assignment operator returns the power of two counterparts.

• #### Php

##### Example of exponentiation assignment operator in php.
``````<?php
\$age = 2;

\$age **= 3;

print(\$age); // 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 not-equal operator checks if two variables are not equal value.

• #### Php

##### Example of not-equal operator in php.
``````<?php
\$age = 20;

print(\$age != 18); // true
``````
• ## Not Equal Type Comparison Operators

• The not-equal type operator checks if two variables are not equal value and type.

• #### Php

##### Example of not-equal type operator in php.
``````<?php
\$age = 20;

print(\$age !== '20'); // true
``````
• ## Greater Than Comparison Operators

• The greater-than operator checks if the value of the first variable is greater than the second.

• #### Php

##### Example of greater-than operator in php.
``````<?php
\$age = 20;

print(\$age > 18); // true
``````
• ## Less Than Comparison Operators

• The less-than operator checks if the value of the first variable is less than the second.

• #### Php

##### Example of less-than operator in php.
``````<?php
\$age = 20;

print(\$age < 21); // true
``````
• ## Greater Than or Equal Comparison Operators

• The greater-than or equal-to operator checks if the value of the first variable is greater than or equal to the second.

• #### Php

##### Example of greater-than or equal-to operator in php.
``````<?php
\$age = 20;

print(\$age >= 20); // true
``````
• ## Less Than or Equal Comparison Operators

• The less-than or equal-to operator checks if the value of the first variable is less than or equal to the second.

• #### Php

##### Example of less-than or equal-to operator in php.
``````<?php
\$age = 20;

print(\$age <= 20); // true
``````
• ## And Logical Operators

• The and operator checks if the value of the first and second variable are true.

• #### Php

• The or operator checks if either the value of the first or second variable is true.

• #### Php

##### Example of or operator in php.
``Coming Soon``
• ## Xor Logical Operators

• The xor operator checks if either the value of the first or second variable is true, but not both.

• #### Php
