Note Submitter: chris at ocproducts dot com ---- Note that error handlers don't run recursively. If you have an error while an error handler is running (in the error handler itself or code called from it) then you won't get the error handler called again. This has subtle ramifications for $php_errormsg. If you are relying on your error handler to suppress certain kinds of error message from going into $php_errormsg (via return true; because error_reporting doesn't affect $php_errormsg setting) then this will not work for any code called within that error handler.
