variable into function but not parameter

[tomas_teicher]

Hi,
it is possible to get variable into function without sending as parameter?

with mysql connection it works

function some_function(){
$result = mysql_query("SELECT * FROM table");
}

but I want to use database with Pear functions
something like:

$dbh = DB::connect($connection_data);

function some_function(){
$result = $dbh->query("SELECT * FROM table");
}

but this doesnt work because $sth has to be sent as parameter of function.
Is there any way to use Pear db queries in functions without sending connection data as parameter?
Thanks
Tomas

You could declare it as [man]global[/man] within the function. However, this is generally frowned upon for a number of reasons. But, if you're going to modify the function anyway, why not make it a function parameter and avoid the problems with global?

thanks for answer,
I probably found solution to solve my problem. I can use MDB2.php instead of DB.php in Pear. I have to study little bit but it is OK. It would be not so bad to pass connection through parameter, too, but this is better for me.
