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.

We use a custom error handler using  set_error_handler()  I found that after I call

libxml_use_internal_errors(false);

It resets my error_handler - not sure if this is a bug or not, I will report it as a bug - however, I needed to repeat my call to set_error_handler

(did confuse me for a while)
