使用PHP从MySQL检索查询结果

Question

I want to query a MySQL database. I have the following. $name keeps changing in a loop. ( $query is a sample query here)

$query = "SELECT id FROM table1 WHERE name='$name';";
$result = mysql_query($query) or die(mysql_error());        
echo "$result<br/>";
While ($row = mysql_fetch_array($result)) {
     echo $row["id"] . " - " . $row["name"];
}

with the echo "$result<br/>" it just prints something like Resource id # . Nothing from $row is printed. The MySQL connection is fine. If I run the query without PHP, it works fine. What might be wrong?

一切都是正确的，直到像循环中那样使用mysql_fetch_array（）或mysql_fetch_assoc（）之类的函数，您才能从$ result中获得任何收益。
