http://php.flashwebhost.com/vineesh/...ariables_5.php

MY CODE IS:

<?php


$numberOfWorkers = 5;
$wagePerWorker = 650;


echo '<p>' . 'Total Number of workers ' . '= ' . $numberOfWorkers . '</p>';


echo '<p>' . 'Wage per worker ' . '= '. $wagePerWorker . '</p>';


echo '<p>' . 'Total wage for all workers will be ' . '= ' . ($numberOfWorkers * $wagePerWorker) . '/-' . "</p>";

<?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.

<?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.
