CGPA Calculator PHP source Code

CGPA stands for Cumulative Grading Point Average.

Today, we are going to talk about making a cgpa calculator which will be made in PHP. I just used simple addition and multiplication in this code. Let's see the interface first:

Let's go through the php souce codes:

<?php

$s1val = $_POST['s1'];
$s2val = $_POST['s2'];
$s3val = $_POST['s3'];
$s4val = $_POST['s4'];
$s5val = $_POST['s5'];
$s6val = $_POST['s6'];


$c1val = $_POST['c1'];
$c2val = $_POST['c2'];
$c3val = $_POST['c3'];
$c4val = $_POST['c4'];
$c5val = $_POST['c5'];
$c6val = $_POST['c6'];




$suball = (( $s1val*$c1val ) + ( $s2val*$c2val ) + ( $s3val*$c3val )+ ( $s4val*$c4val ) + ( $s5val*$c5val ) + ( $s6val*$c6val ) );
$crall = $c1val + $c2val + $c3val+ $c4val+ $c5val+ $c6val;

$cgpa = $suball / $crall;

 $cgpaformated = number_format ($cgpa, 2);

echo "<p>Your CGPA: " . $cgpa . "</p>";
echo "<br/><p>" . " Your CGPA Formated: ". $cgpaformated . "</p>";


if ( $cgpaformated > 3.75 )
 echo "<p><br/>". " .. Oh Boy! You are awesome and outstanding! </p>";

else if ( $cgpaformated > 3.49 && $cgpaformated <= 3.75 )
  echo "<br/>". "<p>You are excellent!! :D Carry on!</p>";


?>


I'm pretty sure, you won't face much problem to understand the idea clearly of this codes. You can go through the full site  for other posts for knowing about other posts and source codes.
