由於v.4到v5遷移，PHP腳本不再起作用

Question

最近我的webserver從PHP v.4遷移到v.5.3。我知道，我知道，很長一段時間:)

但是現在當用戶輸入所需的數據時，我的一些腳本不顯示結果。這裏是腳本：

<?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;?>

看起來像你期待register_globals上。這現在是默認關閉的。

您應該使用$_GET['heightft']或$_POST['heightft']取決於窗體方法來訪問此數據。
