Arithmetic operator in PHP Language

Arithmetic Operator: A arithmetic operation is a used mathematical operation performed. It is many operations performed like addition, subtraction, multiplication, and division.

Example of Arithmetic operator

Addition:a+b or 10+10=20
Here a is operands value (+) Addition is operator and b is operands. It can be used for additional operations performed.

Subtraction:a-b or 20-10=10
Here a is operands value (-) Subtraction sign is operator and b is operands. It can be used as Subtraction operations performed.

Multiplication: a*b or 10*10=100
Here a is operands value (*) Multiplication sign is operator and b is operands. It can be used Multiplication operations performed.

Division:a/b or 10/5=2
Here a is operands value (/) Division sign operator and b is operands. It can be used for Division operations performed.

Modulas:a%b or 10%3=1
Here a is operands value (%) Modules sign operator and b is operands. It can be used Modules operations performed.

Arithmetic Operator  Table

Sign.           Operation.         Example

(+)              Addition                    (a+b)

(-)               Subtraction              (a-b)  

 
(*)              Multiplication         (a*b)

(/)               Division                     (a/b)

(%)            Modules                    (a%b)

How To Use Arithmetic Operator in PHP?

<?php 

$x=13; 

$y=5; 

echo "Addition:".($x+$y)."<br>"; 

echo "Subtraction:".($x-$y)."<br>"; 

echo "Multiplication:".($x*$y)."<br>"; 

echo "Division:".($x/$y)."<br>"; 

echo "Modulas:".($x%$y)."<br>";

*****OUTPUT*****

Addition:18 

Subtraction:8 

Multiplication:65 

Division:2.6 

Modulas:3 

Relational Operator in PHP Language

Relational Operator: Relational operators are used in the comparison of the two operands. It can be using equal operands and condition check in this operator. Relational operator very most and useful operator.

Relational Operator  Table

Sign.      Operation.         Example

(==)           Equal To              (a+b)

(!=)           Not Equal To       (a-b)   

(>)            Greater Than       (a*b)

(<)             Less Than           (a/b)

(>=)   Grater than Or Equal  (a%b)

(<=)   Less Than Or  Equal    (a%b)

Logical Operator in PHP Language

Logical Operators: PHP Language provides three logical operators. logical Operator tests more than one condition to make decisions.

Types of Logical Operator

1.&& AND Operator 
2.|| OR Operator 
3.!  NOT Operator 

1. AND Operator can be used decisions are two values.AND Operator two values are True AND Operator return True. But two values are anyone False AND Operator return False.

2. OR operator performs a logical condition on two expressions. if or Operator can be two expressions are True OR Operator return true. But any of the expressions are False OR Operator return True.

3. NOT operator is very easy Operator. it can be used condition are True NOT Operator returns False and condition are False NOT Operator returns True.

How To Use Logical AND Operator in PHP?

<?PHP

 

$marks=55; 

if($marks>=60) 

{ 

 echo "First division<br>"; 

} 

if($marks<60 && $marks>=45) 

{ 

echo "Second division<br>"; 

} 

if($marks<45 && $marks>=33) 

{ 

echo "Third division<br>"; 

} 

if($marks<33) 

{ 

echo "Sorry!! You are Fail!!<br>"; 

} 

?>

*****OUTPUT*****

Second division

Assignment Operator  Table

Sign.        Operation        Example

(=)            a=b                         (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)

Bitwise Operator in PHP Language

Bitwise Operator: A Bitwise operator is an operation performed on the data bit level.

the bitwise operator is also shift bit right to left.
Note:Bitwise operators are not allowed to float and double.

Bitwise Operator  Table

Sign.        Operation.         Example

(&)           Bitwise AND         (a&b)

(|)             Bitwise OR             (a|b)  

 
(<<)         Bitwise LEFT        (a<<2)

(>>)        Bitwise RIGHT      (a>>2)

How To Use Bitwise Operator in PHP?

<?php 

$x=3; 

$y=5; 

echo "x&y:".($x&$y)."<br>"; 

echo "x|y:".($x|$y)."<br>"; 

echo "x>>1:".($x>>1)."<br>"; 

echo "x<<2:".($x<<2)."<br>"; 

echo "x^y:".($x^$y)."<br>";

 ?> 

*****OUTPUT*****

x&y=1 

x|y=7 

x>>1=1 

x<<2=12 

x^y=6 

Increment Operator in PHP Language

Increment Operator:Increment Operators are useful operators generally used.like++x and x++ means x=x+1.

pre-increment first add one to the operand and then the result is assigned to the variable on the left.

post-increment first assigns the value to the variable on the left and then increments the operand.

Decrement Operator: A Decrement Operator has used the decrease the value. like --x and x--.

Pre-decrement first less one to the operands and then the result is assigned to the variable on the left.

Post-decrement first assigns the value to the variables on the left and then decrements the operands.

How To Use Increment/Decrement Operator in PHP?

<?PHP 

$x=3;

Comments in PHP Language

Comments in PHP: It is used to explain the code to make it more readable. It is not considered as a part of the program, in another word we can say that the compiler ignores the comment.
PHP comments are statements that are not executed by the compiler.

Types of comments in PHP

1. Single line comment

2. Multiline comment

Single line comment: It is used to comment only one line. Two forward slashes(//) are used for single-line comments. Hash Symbol(#)is also used for commenting on a single line.
