It is not shown in the output I attached in my previous message because display_errors is Off in my php.ini, and the line that sets it to On in my script is commented out. > I'm using a Apache/2.2.3 (Win32) PHP/5.2.6 I am not using Apache at all. The same error can be seen when I run the script directly through php on the command line. > Is the script correctly? I have removed the "&" in the loop I know that iterating a DOMNode's children using firstChild and nextSibling by reference causes trouble, thank you. The problem is that it causes trouble with objects unrelated to the loop itself, e.g. to variables defined _after_ the loop has terminated. > and the script returns the attached file. Do you mean it returns what is in the output file _I_ have attached, or did _you_ try to attach something? If that is the case, then your attachment didn't get through. > It looks like a bogus bug? I am certain it _is_ a genuine bug. For example, in PHP when you write: $foo = array(); echo gettype($foo); the output should not be NULL, but in my example script (unmodified, with iteration by reference) things like this start happening at some point.
