SELECT and Class syntaxis problem

[Anon]

This is my first time working with clases and i have a problem with a SELECT on mySQL.

$query="SELECT * FROM foro_nombres WHERE level <= $foro_user->Record[level] ORDER BY id_foro ";

y printed the $query and it returns

SELECT * FROM foro_nombres WHERE level <= Array[level] ORDER BY id_foro

so the problem is variable $foro_user->Record[level] , how can i make it work ?!
