Armstrong Number program in PHP

In this example, programmer stores the values in variables. However, if you interested to see the program about taking values in the form, please see example 2.

<?php

$num=153;
$sum=0;
$temp=$num;
while($temp!=0)
{
$rem=$temp%10;
$sum=$sum+$rem*$rem*$rem;
$temp=$temp/10;
}
if($num==$sum)
{
echo "Armstrong number";
}
else
{
echo "not an armstrong number";
}

?>

<?php

$num=153;

$sum=0;

$temp=$num;

while($temp!=0)

{

$rem=$temp%10;

$sum=$sum+$rem*$rem*$rem;

$temp=$temp/10;

}

if($num==$sum)

{

echo "Armstrong number";

}

else

{

echo "not an armstrong number";

}

Armstrong Number program in PHP with form

In this example, we will take the inputs from the user and store them in variables.

<?php
if (isset($_POST['submit'])) {
	$num=$_POST['number1'];
	$sum=0;
	$temp=$num;
while($temp!=0)
{
$rem=$temp%10;
$sum=$sum+$rem*$rem*$rem;
$temp=$temp/10;
}
if($num==$sum)
{
echo "Armstrong number";
}
else
{
echo "not an armstrong number";
}

} //end of if


?>

<?php

if (isset($_POST['submit'])) {

$num=$_POST['number1'];

$sum=0;

$temp=$num;

while($temp!=0)

{

$rem=$temp%10;

$sum=$sum+$rem*$rem*$rem;

$temp=$temp/10;

}

if($num==

$sum)

{

echo "Armstrong number";

}

else

{

echo "not an armstrong number";

}

} //end of if

Armstrong Number program in PHP with database

In this example, we will take the inputs from the user and temporarily store them in variables and then finally stores them permanently in the database.

<?php
$conn= mysqli_connect('localhost','root','','arm');
if (isset($_POST['submit'])) {
	$num=$_POST['number1'];
	$sum=0;
	$temp=$num;
	$sql="INSERT INTO arm(number1,number2)VALUES('$num','$sum')";
	$run=mysqli_query($conn,$sql);
while($temp!=0)
{
$rem=$temp%10;
$sum=$sum+$rem*$rem*$rem;
$temp=$temp/10;
}

if($num==$sum)
{
echo "Armstrong number";
}
else
{
echo "not an armstrong number";
}

} //end of if


?>

<?php

$conn= mysqli_connect('localhost','root','','arm');

if (isset($_POST['submit'])) {

$num=$_POST['number1'];

$sum=0;

$temp=$num;

$sql="INSERT INTO arm(number1,number2)VALUES('$num','$sum')";

$run=mysqli_query($conn,$sql);

while($temp!=0)

{

$rem=$temp%10;

$sum=$sum+$rem*$rem*$rem;

$temp=$temp/10;

}

if($num==$sum)

{

echo "Armstrong number";

}

else

{

echo "not an armstrong number";

}

} //end of if
