循环还是没有循环？

Question

在这种情况下,使用循环是否更好？

echo "0";
echo "1";
echo "2";
echo "3";
echo "4";
echo "5";
echo "6";
echo "7";
echo "8";
echo "9";
echo "10";
echo "11";
echo "12";
echo "13";

要么

$number = 0;

while ($number != 13)
{
    echo $number;
    $number = $number + 1;
}

Answer 1

前者可能会快一点.后者是一个很大的可读性.选择是你的;)

Answer 2

更好的是

$totalWhatevers = 14;
for ($number = 0; $number < $totalWhatevers ; $number++)
{
    echo $number;
}

其中'totalWhatevers'是描述性的,告诉我们您实际在计算什么.
