计数在0到10之间

Question

我的代码如下所示

$number_of_book=0;
$res_best_book=mysql_query("SELECT * FROM book ORDER BY best DESC");
while($best_book=mysql_fetch_assoc($res_best_book)){
    echo "Number Of Book";$number_of_book++;
    echo "&nbsb;&nbsb;";
    print_r($best_book['book_name']);
    echo "<br>";
}

这是我的实际输出：

Number Of Book   BOOK58   
Number Of Book   BOOK91
Number Of Book   BOOK532
Number Of Book   BOOK1
Number Of Book   BOOK21
Number Of Book   BOOK84

预期输出

Number Of Book 1  BOOK58
Number Of Book 2  BOOK91
Number Of Book 3  BOOK32
Number Of Book 4  BOOK1
Number Of Book 5  BOOK21
Number Of Book 6  BOOK84

Answer 1

试试这个：

$number_of_book=1;
$res_best_book=mysql_query("SELECT * FROM book ORDER BY best DESC");
while($best_book=mysql_fetch_assoc($res_best_book)){
    echo "Number Of Book ".$number_of_book++." ".$best_book['book_name']." <br>";
    $number_of_book++;
}

Answer 2

$number_of_book=1;
$res_best_book=mysql_query("SELECT * FROM book ORDER BY best DESC");
while($best_book=mysql_fetch_assoc($res_best_book)){
    echo "Number Of Book".$number_of_book;
    echo "&nbsb;&nbsb;";
    print_r($best_book['book_name']);
    echo "<br>";
    $number_of_book++;
}
