Taking it to a better solution is that the method sqliteCreateFunction
shouldn't exist on the PDO class, but instead on a PDOSqlite that
extends PDO.
class PDOSqlite extends PDO {
public function createFunction(...) {...}
}
class PDO {
public static function connect(string $dsn [, string $username [,
string $password [, array $options ]]]) {
// if connecting to SQLite DB {
return new PDOSqlite(...);
}
}
}
This might be a mistake in how it was implemented originally. Looking
back it seems that it was implemented before we had the RFC
process....and is exactly the type of 'sub-optimal' implementation the
RFC process is meant to prevent.
Yes I do agree that the method overloading of PDO by drivers is not the best to say the least.
If you feel like rewriting a large part of PDO feel free :) but I don't have time for that, and it's not the subject of this RFC :)
