echo $i;

echo "\t";

$sum=$sum+$i;

}

}

echo "\n";

echo "\n";

?>

 

 While loop:-

<?php

///Wap to find the sum of given series 2+4+6+8.......+500

using while loop.

$sum=0;

$i=2;

while($i<=500)

{

if($i%2==0)

{

echo $i;

echo "\t";

$sum=$sum+$i;

}

$i++;

}

echo "\n";

echo "sum=".$sum;

?>

 

 Do-while loop:-

<?php

///Wap to find the sum of given series 2+4+6+8.......+500

using Do-while loop.

$sum=0;

$i=2;

do

{

if($i%2==0)

{

echo $i;
