voting script in result as percentage ???

[linux1880]

I have written a voting script where we can view a total number of votes per choices ? How do i show the voting result as percentage ?

For each choice you divide the votes by the total number of votes and then multiple by 100 to get the percentage. Example code

// some dummy data to work with
$choices[1] = 6;
$choices[2] = 5;
$choices[3] = 20;

// get the total number of votes
$total_votes = array_sum($choices);

// loop over the choices
foreach($choices as $key => $choice)
{
    // work out the percentage
    $pcent = round(($choice/$total_votes)*100);
    
    // display the result
    echo "Choice{$key}: $choice votes =  %$pcent<br />";
}
