When using this funtion, be sure to clear your internal error buffer. If you dn't and you are using this in a long running process, you may find that all your memory is used up.When using libxml_use_internal_errors(true), and perform a possibly memory intensive operation like simplexml_load_string() next, you might end up with a blank screen and no php error logged because the error message been suppressed.
