Arithmetic Operators

Arithmetic operators perform addition, subtraction, multiplication, division, exponentiation, and modulus operations.

Operators	Meaning	Example	Result
+	Addition	4+2	6
–	Subtraction	4-2	2
*	Multiplication	4*2	8
/	Division	4/2	2
%	Modulus operator to get the remainder in integer division	5%2	1
++	Increment	A = 10; A+ +	11
—	Decrement	A = 10; A− −	9

Relational Operators

Operators	Meaning	Example	Result
<	Less than	5<2	False
>	Greater than	5>2	True
<=	Less than or equal to	5<=2	False
>=	Greater than or equal to	5>=2	True
=	Equal to	5==2	False
!=	Not equal to	5! =2	True
===	Equal value and same type	5 === 5 5 === “5”	True False
!==	Not Equal Value or Not same type	5 ! == 5 5 ! == “5”	False True

Logical Operators

Operators	Meaning	Example	Result
&&	Logical and	(5<2)&&(5>3)	False
\|\|	Logical or	(5<2)\|\|(5>3)	True
!	Logical not	!(5<2)	True

&&

Operand 1	Operand 2	Result
True	True	True
True	False	False
False	True	False
False	False	False

||

Operand 1	Operand 2	Result
True	True	True
True	False	True
False	True	True
False	False	False

!

Operand	Result
False	True
True	False

Bitwise Operators

Operator	Meaning
<<	Shifts the bits to left
>>	Shifts the bits to the right
~	Bitwise inversion (one‟s complement)
&	Bitwise logical AND
\|	Bitwise logical OR
^	Bitwise exclusive or

Bitwise logical AND &

Operand 1	Operand 2	Result (operand1&operand2)
True	True	True
True	False	False
False	True	False
False	False	False

Operand 1	Operand 2	Result (operand1&operand2)
1	1	1
1	0	0
0	1	0
0	0	0

Bitwise logical OR |

Operand 1	Operand 2	Result (operand1\|operand2)
True 1	True 1	True 1
True 1	False 0	True 1
False 0	True 1	True 1
False 0	False 0	False 0

Bitwise XOR ^

Operand 1	Operand 2	Result (operand1^operand2)
True 1	True 1	False 0
True 1	False 0	True 1
False 0	True 1	True 1
False 0	False 0	False 0

Bitwise NOT ~

Operand	Result
True 1	False 0
False 0	True 1

Assignment Operators

Operator	Example	Equivalent Expression
=	𝑚 = 10	𝑚 = 10
+=	𝑚 += 10	𝑚 = 𝑚 + 10
−=	𝑚 −= 10	𝑚 = 𝑚 − 10
∗=	𝑚 ∗= 10	𝑚 = 𝑚 ∗ 10
/ =	𝑚 / =	𝑚 = 𝑚/10
% =	𝑚 % = 10	𝑚 = 𝑚%10
<<=	𝑎 <<= 𝑏	𝑎 = 𝑎 << 𝑏
>>=	𝑎 >>= 𝑏	𝑎 = 𝑎 >> 𝑏
>>>=	𝑎 >>>= 𝑏	𝑎 = 𝑎 >>> 𝑏
& =	𝑎 & = 𝑏	𝑎 = 𝑎 & 𝑏
^ =	𝑎 ^ = 𝑏	𝑎 = 𝑎 ^ 𝑏
\| =	𝑎 \| = 𝑏	𝑎 = 𝑎 \| b

Tutorial for Logical operators

What is Logical operators?

They combine conditionals and are mostly used to track several conditions at the same time. For example, the PHP (or) operator verifies that at least one out of every two is correct. If you want to check if they’re both legitimate, you may use the PHP (and) operator. For further information, see the table below:

Operator Name Example Result
and And $x and $y True if both $x and $y are true
or Or $x or $y True if either $x or $y is true
xor Xor $x xor $y True if either $x or $y is true, but not both
&& And $x && $y True if both $x and $y are true
|| Or $x || $y True if either $x or $y is true
! Not !$x True if $x is not true

Example:-
