Defination:-

In number theory, an armstrong number in a given number base b is a number that is the sum of its own digits each raised to the power of the number of digits. ... If the number obtained equals the original number then, we call that armstrong number.

code:-

<?php  

 

$n=153;  

$sum=0;  

$i=$n;

 

while($i!=0)  

{  

$x=$i%10;  

$sum=$sum+$x*$x*$x;  

$i=$i/10;  

}

 

if($n==$sum)  

{  

echo "$n is an Armstrong Number.";  

}  

 

else  

{  

echo "$n is not an Armstrong Number.";  

}
