Arithmetic, Logical And Comparison Operation

Here, Dot(.) is used to concate the statements. <br> tag is used to break the line.

<?php
	$a=10;
	$b=20;
	echo "Value of a = $a"."<br>";
	echo "Value of b = $b"."<br>";

	echo "<br> ***Arithmetic Operator*** <br>";
	
	$c=$a+$b;
	echo "Addition of $a and $b = $c"."<br>";
	
	$c=$a-$b;
	echo "Subtraction of $a and $b = $c"."<br>";
	
	$c=$a*$b;
	echo "Multiplication of $a and $b = $c"."<br>";
	
	$c=$a/$b;
	echo "Division of $a and $b = $c"."<br>";	

	echo "<br> ***Comparison Operator*** <br>";
	
	if($a>$b)
	{
		echo "$a is greater than $b <br>";
	}
	else if($a<$b)
	{
		echo "$a is less then $b <br>";
	}
	else if($a==$b)
	{
		echo "$a and $b is same <br>";
	}

	echo "<br> ***Logical Operator*** <br>";
	
	if($a>0 && $a<50)
	{
		echo "$a is between 0 and 50 <br>";	
	}
	else if($a>50 && $a<100)
	{
		echo "$a is between 50 and 100 <br>";
	}
?>

OutPut

Value of a = 10
Value of b = 20

***Arithmetic Operator*** 
Addition of 10 and 20 = 30
Subtraction of 10 and 20 = -10
Multiplication of 10 and 20 = 200
Division of 10 and 20 = 0.5

***Comparison Operator*** 
10 is less then 20 

***Logical Operator*** 
10 is between 0 and 50
