In Lab 6 you will complete ALL steps of lab 6-1. However, youwill turn in ONLY the required items listed below.
1. Compress all code (one compressed file) in which you addedEcho statements for debugging.
<?php // get the data from the form $investment = filter_input(INPUT_POST,'investment', FILTER_VALIDATE_FLOAT); $interest_rate = filter_input(INPUT_POST,'interest_rate', FILTER_VALIDATE_FLOAT); $years = filter_input(INPUT_POST,'years', FILTER_VALIDATE_INT);
// validate investment if ( $investment === NULL || $investment === FALSE ){ $error_message = 'Investment must be avalid number.'; } else if ( $investment <= 0 ) { $error_message = 'Investment must begreater than zero.'; }
// validate interest rate else if ( $interest_rate === NULL || $interest_rate=== FALSE ) { $error_message = 'Interest rate must bea valid number.'; } else if ( $interest_rate <= 0 ) { $error_message = 'Interest rate must begreater than zero.'; } // validate years else if ( $years === NULL || $years === FALSE ){ $error_message = 'Number of years mustbe a valid whole number.'; } else if ( $years <= 0 ) { $error_message = 'Numbr of years mustbe greater than zero.'; }
// set error message to empty string if no invalidentries else { $error_message = ''; }
// if an error message exists, go to the indexpage if ($error_message != '') { include('index.php'); exit(); }
// calculate the future value $future_value = $investment; for ($i = 1; $i <= $years; $i++) { $future_value += $future_value *$interest_rate; }
// apply currency and percent formatting $investment_f = '$'.number_format($investment,2); $yearly_rate_f = $interest_rate.'%'; $future_value_f = '$'.number_format($future_value,2);?><!DOCTYPE html><html><head> <title>Future ValueCalculator</title> <link rel="stylesheet" type="text/css"href="main.css"/></head><body> <main> <h1>Future ValueCalculator</h1>
