Hello,
I am learning PHP5. I need to parse XML file and I found a solution in some
book on PHP5 ("PHP5 Programming" by Rasmus Lerdors and others).
Unfortunately I have two problems that I don't understand:
Warning: Call-time pass-by-reference has been deprecated; If you would like
to pass it by reference, modify the declaration of xml_set_object(). If you
would like to enable call-time pass-by-reference, you can set
allow_call_time_pass_reference to true in your INI file.

Parse error: syntax error, unexpected ';', expecting T_FUNCTION
