We are going to create a simple poll that users may select what programming laguage they prefer (ASP or PHP)
First of all prepare four files as below:
1. asp.txt and then insert the number 0 in it as initial value.
2. php.txt and then type the number 0 in it as initial value.
Note: Do not forget to insert the value 0 in the asp.txt and php.txt. This is very important so that the script works
3. create an image file poll.jpg with size 100x10px. This is to make the percentage of polling.
This is also important to make our poll eye-catching.
4. index.php and type in it the script below
<title> Simple Polling </ title>
<style type="text/css">
<! --
. style1 (font-size: 24px)
. style2 (color: # 0000FF)
->
</style>
<form name="form1" method="post" action="index.php?content=polling">

$readasp = fgets($open_asp, 65535); // read the value for asp
fclose($open_asp);
$total_user = $readphp + $readasp; // the number of voters
$persentase_php = ($readphp / $total_user) * 100;
$persentase_asp = ($readasp / $total_user * 100);
echo "Total voters: $total_user <br>";
echo "PHP:"; printf("% 1.0f", "$persentase_php"); echo "% <img src=poll.jpg width =$persentase_php $height = 10 /> $readphp voters <br> ";
echo "ASP"; printf("% 1.0f", "$persentase_asp"); echo "% <img src = poll.jpg width =$persentase_asp $height = 10 /> $readasp voters <br> ";
}
?>
