初学函数的困惑

[freescy2002]

想法，想构造一个函数,各自用各自的，为什么无法输出，初学函数，请大家帮助一下，谢谢。
<?
require "../config.php";

function db_user($d_table,$w_select,$d_select)
{
$SQL="select id,user,pass,address from $d_table where $w_select = '$d_select'";
$result=mysql_query($SQL) or die(mysql_error());
$record=mysql_fetch_object($result);
$count=mysql_num_rows($result);

}
............其他的函数

db_user("s_user","id",$strap_id);
echo $record->id;
echo $record->pass;//为什么这里都没有输出的
echo $record->address;
?>

{
$SQL="select id,user,pass,address from $d_table where $w_select = '$d_select'";
$result=mysql_query($SQL) or die(mysql_error());
$record=mysql_fetch_object($result);

while ($row = mysql_fetch_object($result)) {
echo $record->id;
echo $record->pass;
echo $record->address;
}
}
db_user("s_user","id",$strap_id);

?>


//$count=mysql_num_rows($result);这句话你要他干吗??!!

感谢你的答案，我的意思是说
function db_user($d_table,$w_select,$d_select)
{
$SQL="select id,user,pass,address from $d_table where $w_select = '$d_select'";
$result=mysql_query($SQL) or die(mysql_error());
$record=mysql_fetch_object($result);


}
这个当一个函数来封装一下。
db_user("s_user","id",$strap_id);来调用，以后一旦有数据库操作就用这个
echo $record->id;
echo $record->pass;
echo $record->address;
这些是调用以后可以输出，可能小弟表达的不对，刚学，不是很懂。

这个啊
我实现过的

不简单的哦

$result=mysql_query($SQL) or die(mysql_error());
$record=mysql_fetch_object($result);
return $record;
}

$record=db_user("s_user","id",$strap_id);
echo $record->id;
echo $record->pass;
echo $record->address;
