好奇怪啊，往记事本里添加数据，用t分割，结果每个tab键的长度不一致？不一致？

源代码如下，是两个文件，一个提交数据，一个处理数据。

Bob's auto Parts

Order Results

echo "

Order Precessed at ";
echo date('H:i,jS F');
echo "

";
?>

$totalqty = 0;
print_r($_POST);
echo "

$tireqty = $_POST['tireqty'];
$oilqty = $_POST['oilqty'];
$sparkqty= $_POST['sparkqty'];
$address = $_POST['address'];
$DOCUMENT_ROOT = $_SERVER['DOCUMENT_ROOT'];
$totalqty = $tireqty+$oilqty+$sparkqty;
$date = date('H:i,jS F Y');
echo "Item Ordered: $totalqty
";
if ($totalqty==0) {
echo "You did not order anything on the Bob's site!";
} else {
if ($tireqty>0) {
echo $tireqty."tireqty

}
if ($oilqty>0){
echo $oilqty."oilqty

}
if ($sparkqty>0) {

}
}

$totalamount = 0.00;

这是记事本的问题，你用 notepad++之类的编辑器打开文本文件就好了。

这个与tab等于多少空格有关。记事本貌似是是8。
