[PATCH] sqlite: retrieve SQL syntax errors

Hi, I've made a simple patch to allow a user to retrieve the SQL syntax error occured in either sqlite_exec(), sqlite_query() or sqlite_unbuffered_query(). Untill now this wasn't possible, because sqlite_last_error() doesn't handle SQL syntax errors. The patch adds an additional parameter to those 3 functions (OO and non-OO versions) to retrieve the error. Patch: http://mega.ist.utl.pt/~ncpl/php_sqlite.txt Example: <? $idx = sqlite_open(':memory:'); @sqlite_exec($idx, 'SELECT column', $error); echo $error; ?> I hope this can enter in PHP 5.1.0, as it is a fairly simple patch. Nuno P.S.: the patch also fixes a bug in the SQLiteDatabase constructor, where the $errorstr variable wasn't filled (because it wasn't beeing passed by reference).
