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 Assignment operators

What is Assignment operators?

PHP Assignment operators are used to assign values to variables. The right side value is substituted for the left side value in the operand variable. Operators in this category are in charge of assigning variables. The most frequent assignment operator is =, which assigns the operand’s right side to the left variable.

Assignment Same as… Description
x = y x = y The left operand gets set to the value of the expression on the right
x += y x = x + y Addition
x -= y x = x - y Subtraction
x *= y x = x * y Multiplication
x /= y x = x / y Division
x %= y x = x % y Modulus

Example:-

Output:-
