我通常将结果放在数组中

I usually do this by placing the results in an array first

$some_array = array();
while($row0 = mysql_fetch_array($result0, MYSQL_ASSOC)) {
   $some_array[] = $row0['LCASE(ord)'];
}

那么简单：

echo "My List: " . implode(', ', $some_array);
// Output looks something like:
My List: ord1, ord2, ord3, ord4
