Can I use this php code wih WHERE? SELECT SUM(buzz) as buzz FROM $table I want to calculate sumation of some spesific rows.
If you want specifically in PHP then this might help you
SELECT SUM(buzz) as buzz FROM $table WHERE $where
No, you can't use PHP code in an SQL where condition. Databases typically don't include a PHP interpreter.
What you can do is use PHP to generate the where clause that you need.

This is explained in the docs, which you should definitely start reading now:
When a string is specified in double quotes or with heredoc, variables
are parsed within it.
And follow this link: http://php.net/manual/en/language.types.string.php#language.types.string.parsing

In learing mongo with php,I have a tiny problem,
that is all,any help would be great appreciated！
You need to read this MongoPHPQueries Page and probably before that you need to do as #RocketHazmat said and start with this MongoPHP Tutorial.
But here is something that might help you with the data you are trying to find.
$cursor = $collection->find(array("addressse.0.state" => "NY"));
The above will give you a cursor allowing you to iterate over each record that is returned. Hope this helps.
FYI - You need more than just that line above to get that to work. So follow the links.

Use cURL to fetch the page and then use something like DomDocument to get the exact data that you want.
