Wordpress使用functions.php中的外部查询结果

I have a custom php page outside of wordpress, this page is connecting also to a external database, and get resultat form a sql query on a variable

i use require('../wp-blog-header.php') and require('../wp-load.php') to integrate with wordpress.

now i need to use this variable on the functions.php of my wordpress theme.

i do on my external page :

<head>
<connect to my database>
<my query>
<get resulte on $variable>
<require('../wp-blog-header.php')>
<require('../wp-load.php')>

but when i use $variable on my functions.php it do not work ?

    You need to include wp-load.php alone. It will load wp-include (and wpdb), plugins and your theme (functions.php). To use the database directly you would do this: 

    global $wpdb;
$wpdb->get_results('select ...');

    If you need to access variable declared in functions.php, it's straight forward:

    say.php

    <?php
include 'var.php';
print_r( $moo );
?>

    var.php

    <?php
$moo= 'cow';
?>

    output of say.php

    $ php say.php 
cow

    Loading (include or require) functions.php after wp-load.php will result in redeclaration of the functions defined within functions.php (it will be loaded twice), causing PHP to crash.
