从while循环获取计数器的更简单方法? [英] easier way to get counter from while loop?

问题描述

我有以下内容:

$counter = 1;   
while($row= mysql_fetch_assoc($result)) {
    $counter2 = $counter++;

    echo($counter2 . $row['foo']);
}

是否有一种更简单的方法来获得每个结果的1,2,3等，还是最好的方法?

Is there an easier way to get 1,2,3 etc for each result or is this the best way?

谢谢

推荐答案

您不需要$ counter2. $ counter ++很好.如果您使用预增量而不是后增量，则甚至可以在与回显相同的行上执行此操作.

You don't need $counter2. $counter++ is fine. You can even do it on the same line as the echo if you use preincrement instead of postincrement.

$counter = 0;   
while($row= mysql_fetch_assoc($result)) {
    echo(++$counter . $row['foo']);
}
