根据百分比显示是或否

Question

我试图找到一种基于百分比显示“是”和“否”的简单方法。 这只是一个例子，但在vb.net上，我可以设置静态并做这样的事情（70％和30％）

        Static iNo As Long, iYes As Long
        If iNo > iYes * 0.42 Then
            iYes = iYes + 1
            Return False 'this is the 70%
        Else
            iNo = iNo + 1
            Return True 'this is the 30%
        End If

我究竟能用PHP完成这么简单的事情吗？

Answer 1

$numVotes = 100;
$trueVotes = 70;
$falseVotes = 30;

function addVote($boolVote){

    $numVotes++;
    if($boolVote)

       $trueVotes++:
       return $trueVotes * $numVotes / 100; //percent of true votes
    }
    else{

       $falseVotes++;
       return $falseVotes * $numVotes / 100; //percent of false votes
}

$newVote = true;
$percent = addVote($newVote);

($newVote)$strVote = "true":$strVote = "false";

echo sprintf("The vote is %s and the percent is %01.2f", $strVote, $percent);
