Question

最近我的网络服务器从PHP v.4迁移到v.5.3。我知道，我知道，很长一段时间来了:)。

但是现在，当用户输入所需数据时，我的许多脚本都不会显示结果。这是脚本：

<?php 
if ($ok) {

    if ($heightft == "" || $heightin == "" || $weight == "") {
        $error = "<br><FONT COLOR=#FF0000>One of the fields above was not completed.</FONT><br>";
    } else {
        $bmi = $weight * 703 / (($heightft * 12 + $heightin) * ($heightft * 12 + $heightin));
        $bmiString = number_format($bmi,2,".","");
        echo "<table border='1' cellpadding='10' bordercolor='0000FF'><tr><td><strong>Your BMI is: " . $bmiString;
echo "<br><br></strong>";

        if ($bmi <= 18.50) { 
            echo "You are classified as <strong>Underweight</strong>."; 
        } elseif ($bmi <= 24.99) {
            echo "You are classified as <strong>Normal</strong>."; 
        } elseif ($bmi <= 29.99) {
            echo "You are classified as <strong>Overweight</strong>."; 
        } else { 
            echo "You are classified as <strong>Obese</strong>.</td></tr></table></bordercolor>"; 
        }       
    }
}

?>

<?php echo $error;?>

看起来你期待register_globals开启。现在默认情况下已关闭。

您应该使用$_GET['heightft']或$_POST['heightft']，具体取决于表单方法来访问此数据。

由于v.4到v5的迁移，PHP脚本不再有效
