PHP Different Operators !!
PHP Operators
Operators are used for perform different kinds of operation on values.
We can do different operation using operators on different values.
There are operators we can use in PHP
Arithmetic Operators
Arithmetic operators are used to perform simple mathematical operations like addition, subtraction, multiply, division and modulo.
| operator | syntax | operation |
|---|---|---|
| + | $a + $b | addition of operands |
| - | $a - $b | subtraction of operands |
| * | $a * $b | multiplication of operands |
| / | $a / $b | division of operands |
| % | $a % $b | reminder of operands |
Program :
<?php
$x= 10 $y= 3
echo "The sum is : ". ($x+$y)
echo "The difference is : ". ($x-$y)
echo "Multiplication is : ". ($x*$y)
echo "Division is : ". ($x/$y)
echo "Modulus is : " . ($x%$y)
?>
echo "The difference is : ". ($x-$y)
echo "Multiplication is : ". ($x*$y)
echo "Division is : ". ($x/$y)
echo "Modulus is : " . ($x%$y)
?>
Output :
The sum is : 13
The difference is : 7
Multiplication is : 30
Division is : 3.333333
Modulus is : 1
The difference is : 7
Multiplication is : 30
Division is : 3.333333
Modulus is : 1
Logical Operators
This operators are used in conditional statements.it is used to check true or false conditions.
Operators is used like logical and, logical or, logical not, and, or, xor.
| operator | syntax | operation |
|---|---|---|
| && | $a && $b | true if both operands are true otherwise false |
| || | $a || $b | true if either one of both operands are true otherwise false |
| ! | !$b | true if $b false |
| and | $a and $b | true if both operands are true otherwise false |
| or | $a or $b | true if either one of both operands are true otherwise false |
| xor | $a xor $b | false if both operands are true otherwise true |
Program :
<?php
$name=”Nibkarma”;$pass=”123”;
if($name==”NibKarma” && $pass==”123”){echo “Welcome to Nibkarma”;}else{echo “Invalid username or Password”;}
?>
Output :
$name=”Nibkarma”;$pass=”123”;
if($name==”NibKarma” && $pass==”123”){echo “Welcome to Nibkarma”;}else{echo “Invalid username or Password”;}
?>
Output :
Welcome to NibKarma
Comparison Operators
Comparison operators are used to compare the variables.
It returns the Boolean value either true or false.
Operators like <, >, <=, >=, ==, != is used.
| operator | syntax | operation |
|---|---|---|
| > | $a > $b | true if a is greater then b |
| >= | $a >= $b | true if a is greater then or equal to b |
| < | $a < $b | true if a is less then b |
| <= | $a <= $b | true if a is less then or equal to b |
| == | $a == $b | true if both operands are same |
| != | $a != $b | true if a is not equal to b |
Program :
<?php
$a =5;$b =7;
if($a==$b){echo “Equal”;}else{echo “Not Equal”}
?>
$a =5;$b =7;
if($a==$b){echo “Equal”;}else{echo “Not Equal”}
?>
Output :
Not Equal
Assignment Operators
Assignment operation used to assign value to the operator without do extra operations.
Operators like =, +=, -=, *=, /=, %= is used.
| operator | syntax | operation |
|---|---|---|
| = | $a = $b | true if a is equal to b |
| += | $a += $b | addition as $a = $a + $b |
| -= | $a -= $b | subtraction as $a = $a - $b |
| *= | $a *= $b | multiplication as $a = $a * $b |
| /= | $a /= $b | division as $a = $a / $b |
| %= | $a %= $b | modulo as $a = $a % $b |
Program :
<?php
$a=12;$b=$a;
echo $b; echo "<br>";
$a+=$b;echo $a;echo "<br>";
$a-=$b;echo $a;echo "<br>";
$a*=$b;echo $a; echo "<br>";
$a/=$b;echo $a;echo "<br>";
$a%=$b;echo $a;echo "<br>";
$a.=$b;echo $a;
?>
Output :
122412144120012
Increment/Decrement Operators
This operators are used for increment or decrement the value of operators.
++ and -- operators are used.
| operator | syntax | operation |
|---|---|---|
| ++ | ++$a | pre-increment : first increment then prints |
| ++ | $a++ | post-increment : first print then increment |
| -- | --$a | pre-decrement : first decrement then print |
| -- | $a-- | post-decrement : first print then decrement |
Program :
<?php
$a=12;$b=++$a;echo "a=".$a." ,b=".$b; //prints a=13 ,b=13echo "<br>";
$b=$a++;echo "a=".$a." ,b=".$b; //prints a=14 ,b=13echo "<br>";
$b=--$a;echo "a=".$a." ,b=".$b; //prints a=13 ,b=13echo "<br>";
$b=$a--;echo "a=".$a." ,b=".$b; //prints a=12 ,b=13echo "<br>";
?>
Output :
a=13 ,b=13a=14 ,b=13a=13 ,b=13a=12 ,b=13
String Operators
String operators are used for string concatenation and assign value to string.
' . ' and '.= ' operators are used.
| operator | syntax | operation |
|---|---|---|
| . | $a.$b | concatenated $a and $b |
| .= | $a.=$b | It concatenated and then assign as $a = $a.$b |
Conditional And Ternary Operators
Conditional Operators are used to compare the values.
It works as a if-else statement.
Ternary operator is ?:
Syntax :
$var = (condition)? $a : $b ;
If condition is true then it returns $a otherwise $b.
