我的代码上有这些

$from_m = 1;
$to_m = 6;

while( $from_m <= $to_m )
{
    if($from_m == 1)
        $m = "January";

    if($from_m == 2)
        $m = "February";

    if($from_m == 3)
        $m = "March";


    $add = "OR month = '$m' ";

    $from_m++;
}

因此

$add = "OR month = 'March' ";

我想要的是...

 $add = "OR month = 'January' OR month = 'February' OR month = 'March' ";

我该怎么做？

有什么帮助吗？

替换这个

$add = "OR month = '$m' ";

和

$add .= "OR month = '$m' ";

采用：

$add .= "OR month = '$m' ";

代替

$add = "OR month = '$m' ";
