PHP Operators With Examples And Programms
\\ If you have any query or questions on my post, then please comment below // Operators In PHP:
Following are the operators of PHP:
- PHP Arithmetic Operator.
- PHP Assignment Operator.
- PHP String Operator.
- PHP Increment / Decrement Operator.
- PHP Comparison Operator.
- PHP Logical Operator.
- PHP Array Operator.
Arithmetic Operators With Example In PHP:
In php language, we can do all arithmetic operators as we do in other language.
Operators Are: +, -, *, /, %.
Program: Write a program to perform addition, subtract, multiplication, division, module division.
<?php
$num1 = 10;
$num2 = 20;
$addition = $num1+$num2;
echo"Addition Of Two Numbers is =";
echo $addition;
$subtraction = $num2 - $num1;
echo"Subtraction Of Two Numbers is =";
echo $subtraction;
$multiply=$num1*$num2;
echo"Multiplication of two numbers is = ";
echo $multiply;
$division=$num2/$num1;
echo"Division of two numbers is = ";
echo $division;
$moduledivision = $num2%$num1;
echo"Module Division Of Two Number is = ";
$moduledivision;
?>
Assignment Operators With Examples In PHP:
Operator Another Way Description
A = b a = b Here value of b is going to shift in a.
a += b a = a + b Addition
a -= b a = a - b Subtraction
a *= b a = a * b Multiplication
a /= b a = a / b Division
a %= b a = a % b Modulus
Write a program to perform string operators in php.
<?php
$a=10;
echo $a;
$b=20;
$b += 100;
echo $b;
$c=50;
$c -= 25;
echo $c;
$d=5;
$d *= 6;
echo $d;
$e=10;
$e /= 5;
echo $e;
$f=15;
$f %= 4;
echo $f;
?>
Please run this program and see the output and write output below the comment box.
String Operators With Example In PHP:
Operator Name Example Result
. Concatenation $a = "Technical"
$b = $a . " Programming" Now $b contains "Technical Programming"
.= Concatenation $a = "Technical"
Assignment $a .= "Programming" Now $a contains "Technical Programming"
Increment / Decrement Operators With Example In PHP:
Operators Name Description
++$a Pre-increment First Increase $a by one, then returns the value of $a
$a++ Post-increment First returns $a value, then do increment $a by one
--$a Pre-decrement First decrements $a by one, then returns value of $a.
$a-- Post-decrement First returns the value of $a, then decrease the value of $a by one.
Write a program to perform increment and decrement operation.
<?php
$a=100;
echo ++$a;
// outputs 101
$b=20;
echo $b++;
// outputs 20
$c=50;
echo --$c;
// outputs 49
$d=12;
echo $d--;
// outputs 12
?>
Comparison Operators With Example In PHP:
Operator Name Example Result With Description
== Equal $a == $b True if $a is equal to $b.
=== Identical $a === $b True if $a is equal to $b, and they are of the same type.
!= Not equal $a != $b True if $a is not equal to $b.
<> Not equal $a <> $b True if $a is not equal to $b.
!== Not identical $a !== $b True if $a is not equal to $b.
> Greater than $a > $b True if $a is greater than $b.
< Less than $a < $b True if $a is less than $b.
>= Greater than equal to $a >= $b True if $a is greater than or equal to $b.
<= Less than or equal to $a <= $b True if $a is less than or equal to $b.
Logical Operators With Example In PHP:
Operator Name Example Result
and And $a and $b True if both $a and $b are true.
or Or $a or $b True if either $a or $b is true.
xor Xor $a xor $b True if either $a or $b is true, but not both true.
&& And $a && $b True if both $a and $b are true.
|| Or $a || $b True if either $a or $b is true.
! Not !$a True if $a is not true.
Array Operators With Example In PHP:
Operator Name Example Result
+ Union $a + $b Union of $a and $.
== Equality $a == $b True if $a and $b have the same key or value pair.
=== Identity $a === $b True if $a and $b have the same key or value pairs in the
same order and of the same types
!= Inequality $a != $b True if $a is not equal to $b
<> Inequality $a <> $b True if $a is not equal to $b
!== Non-identity $a !== $b True if $a is not identical to $b
