带有php的UL列表同时声明，怎么做对了？

Question

Here is the code ...

<?php
    $query = mysql_query("SELECT * FROM subjects");
    while($fetch = mysql_fetch_array($query)){
    echo "<li>" .  $fetch["menu_name"] . "</li>";   
        echo "<ul>";
        $query = mysql_query("SELECT * FROM pages WHERE subject_id = {$fetch["id"]}");
        while($fetch = mysql_fetch_array($query)){
        echo "<li>" .  $fetch["menu_name"] . "</li>";}
        echo "</ul>";
    }?>

the problem is that it gets one "subject" and the rest of the "pages" under it ...

I want it to get all subjects and all pages under it

I hope that you understood me Thanks in advance FarrisFahad

Answer 1

I might be wrong. But possibly because you are using the variable $query for both of the mysql queries. Try using a different variable, such as $query1 or an other such useful name for the inner one.
