$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.

<?php

$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.
