Code

<?php

$costOfApple = 100;
$costOfOrange = 70;
$totalCost = $costOfApple + $costOfOrange;
$discount = 0.2;


echo 'Cost of Apple = Rs. ' . $costOfApple . ' /- <br>';
echo 'Cost of Orange = Rs. ' . $costOfOrange . '/- <br>';
echo 'Total Cost = Rs. ' . $totalCost . '/- <br>';
echo 'Discount = Rs. ' . $totalCost * $discount . '/-  <br>' ;
echo 'Cost after discount = Rs. ' . ( ( $totalCost ) - ( ($totalCost) * $discount )) . '/- <br>';

 <?php


$name = 'Raju';

$place = 'Ernakulam';

$job = 'Designer';

$nation = 'india';

$age = '30';

echo $name . ' from ' .  $place . '. Working as ' . $job. '. Nationality ' . $nation . ' . Age ' . $age;

$age = '30';

Since age is numeric, no need to use single quote. For numeric values, use as follows

$age = 30;

Everything else looks good.

<?php


$numoflilly = 50;
$numofjasmin =30;

echo 'Total number of flowers = '.($numoflilly+$numofjasmin);

Name of variables are difficult to understand. Use

$numOfLilly = 50;
$numOfJasmin =30; 

Variable name always start with smaller cause letter.

If variable name have more than one word, capitalize first letter of each word.

DAY 2 PHP PROGRAMMING

<?php

$mobile_price = 2500;
$mobile_pouch = 300;
$discount = 0.07; //7% discount.

echo 'Total Cost = Rs: ' . ($mobile_price + $mobile_pouch) . '/-';
echo'<br>';
echo'Price After discount = Rs: ' . (($mobile_price + $mobile_pouch) - (($mobile_price + $mobile_pouch) * $discount)). '/-';

Variable naming is not proper.

echo'<br>'; 

Need a space after echo.
