How to use PHP 4 classes with exceptions?

Hello, PHP 5.04, PEAR 1.4.0a11 what is the best way to use PEAR classes written for PHP 4 with exceptions to write code like <?php require_once 'PEAR.php'; require_once 'DB.php'; try { $db = DB::connect('pgsql://usr:pw@localhost/dbnam'); // Proceed with a query... $res = $db->query('SELECT * FROM clients'); } catch (Exception $e) { echo 'Caught exception: ', $e->getMessage(), "\n"; } ?> Using PEAR::setErrorHandling(PEAR_ERROR_EXCEPTION) returns a warning Warning: PEAR_ERROR_EXCEPTION is obsolete, use class PEAR_ErrorStack for exceptions in ...php-5.0.4/lib/php/PEAR.php on line 890 but the PEAR_ErrorStack does not support exception without an own callback * Since version PEAR1.3.2, ErrorStack no longer instantiates an exception class. This can * still be done quite handily in an error callback or by manipulating the returned array So at the moment I'm just using a PEAR error handler to throw exceptions PEAR::setErrorHandling(PEAR_ERROR_CALLBACK, 'pearErrorHandler'); function pearErrorHandler($error) { throw new Exception($error->getMessage() . ' -- ' . $error->getDebugInfo()); } but using PEAR::setErrorHandling(PEAR_ERROR_EXCEPTION) would be easier. So what is the best way to use PEAR classes written for PHP 4 with exceptions? tschuess [|8:)
