| Php Operators and their Description |
Php Operators to test if two values are identical
Php Operators: A Php Language is a Special operator that is a mathematical
operation performed in the Php language. Operator Can be used to solve the
mathematical process and Perform logically. Operators have used variables and
data calculation.
Types of operators in Php
1. Arithmetic Operator 2. Relational Operator 3. Logical Operator 4. Assignment operator 5. Bitwise Operator 6. Increment operator 7. Decrement Operator 8. Conditional Operator |
Php Arithmetic operators
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 for 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.
Modules: a%b or 10%3=1
Here a is operands value (%) Modules sign operator and b is operands. It can be used to Modules operations performed.
Php Arithmetic Operator Table
Sign | Operation | Example |
(+) | Addition | (x+y) |
(-) | Subtraction | (x-y) |
(/) | Multiplication | (x*y) |
(*) | Division | (x/y) |
(%) | Modules | (x%y) |
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/$y)."<br>"; echo "Modules:".($x%$y)."<br>"; *****OUTPUT***** Addition:18 Subtraction:8 Multiplication:65 Division:2.6 Modulas:3 |
Php Comparison Operators
Comparison Operator: Comparison operators are used in the comparison of the two operands.
It can be using equal operands and condition checks in this operator. The Comparison operator is very the most useful operator.
Php Comparision Operator Table
Sign | Operation | Example |
(==) | Equal | (a=b) |
(!=) | Not Equal To | (!a=b) |
(>) | Greater Than | (a>b) |
(<) | Less Than | (a<b) |
(>=) | Greater Than or Equal | (a>=b) |
(<=) | Less Than or Equal | (a<=b) |
Php Comparison Operator
<?php $a = 80; $b = 50; $c = "80"; var_dump($a == $c) + "\n"; var_dump($a != $b) + "\n"; var_dump($a <> $b) + "\n"; var_dump($a === $c) + "\n"; var_dump($a !== $c) + "\n"; var_dump($a < $b) + "\n"; var_dump($a > $b) + "\n"; var_dump($a <= $b) + "\n"; var_dump($a >= $b); ?> *****OUTPUT***** bool(true) bool(true) bool(true) bool(false) bool(true) bool(false) bool(true) bool(false) bool(true) |
Php Logical Operators
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 elementary Operator. it can be used condition are True NOT
Operator returns False and condition are False NOT Operator returns True.
Logical 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 |
Php 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) |
Php Bitwise Operators
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<<b) |
(>>) | Bitwise RIGHT | (a>>b) |
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 |
Php Increment/Decrement Operator
Increment
Operator: Increment Operators are useful operators generally used.like++x and
x++ means x=x+1.
pre-increment
first adds 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.
increment/decrement operator
<?PHP $x=3; $y=5; echo "Increment ++x:".++$x."<br>"; echo "Decrement --y:".--$y."<br>"; ?> *****OUTPUT***** Increment ++x:4 Decrement --y:4 |
Php Conditional Operator
Conditional Operators: If the condition is true second part will execute otherwise third part will execute.
Conditional Operator in Php
<?php $x=3; $y=5; $str=$x>$y?"x is greater":"y is greater"; echo $str; ? *****OUTPUT***** y is greater |
