+GitHub issue 1258 - is_callable() throws an exception if PDOStatement method does not exist
+--DESCRIPTION--
+The test shows is_callable() will return false if PDOStatement method does not exist instead of throwing an exception. The user can still check errorInfo() for the error message. See documentation https://www.php.net/manual/en/function.is-callable.php
+--ENV--
+PHPT_EXEC=true
