php mysql 不能用 mysql_num_rows()嗎?

lakupo

Warning: supplied argument is not a valid MySQL result resource in /home/amopopo/public_html/db.php on line 7
Rows

這是怎么一回事?以下是我原本的code:

[code]
<?php

$link = mysql_connect("localhost", "amopopo_amopopo", "tinmouse18");
mysql_select_db("amopopo_payment");

$result = mysql_query("SELECT * FROM user", $link);
$num_rows = mysql_num_rows($result);

echo "$num_rows Rows\n";

?> code]

cloudkia

$result = mysql_query("SELECT * FROM user");
$num_rows = mysql_num_rows($result);

echo "$num_rows Rows\n";

试看。。
