Static Util Classes: Who's creates the DB Connection?

Recommended Posts

I'm programming in an OO mannor. I have several util, factory, and DAO classes. My question is, who should be creating the database connection? Should the connection get aggregated into the static method or should the method create its own connection. Consider the following example:

 

class TemplateUtil
{
// Method creates its own connection and logic is fully encapsulated 
public static function convertSiteNameToID($name)
{
	$name = strtoupper(trim($name));
	$conn = ADOConnectionUtil::createDefaultConnection("flashfac_templates");
	$sql = "SELECT id FROM templates WHERE name = '$name'";
	$row = $conn->GetRow($sql);
	$id = $row["id"];

	return $id;
}

   // Method needs a connection passed into it and relies on the context to 
   // do so....perhaps this makes less connections and more control who connects when.
public static function convertSiteNameToID($conn, $name)
{
	$name = strtoupper(trim($name));
	$sql = "SELECT id FROM templates WHERE name = '$name'";
	$row = $conn->GetRow($sql);
	$id = $row["id"];

	return $id;
}
}

 

I don't have enough experience with php to know what is the better of the options. Any ideas?

 

Thanks guys! :)
