well, when I saw ur post I got immediately the thought I would bed it has to do with some stuff of $this or self. I did play arround a bit with class creation the last days and yes, with using self parent and $this I did put the HTTPPD in unstable and sometimes it died without beeing able to send any error. well this doesn't help very mutch. I have two point: (1)ur code is ( sorry ) lazy written, invest the brackets !! ur code writing is predestinated for that type of error. shooting variable types arround by pulling out of foreach loops, if's, .... is typical. (2) using static variables are known for type missmatch errors just anything has acces to them even if the containing class is not instantinated. many dirty things can happen unless of corse they are not private. further sugestions: check if you work on ur arrays with functions returning array on success but false on fail or something like that. also a typical source for that type of error are u using magic __set ? I ran into a type change as well with it good luck ralph_deffke@xxxxxxxx "Szczepan Holyszewski" <webmaster@xxxxxxxxxxxxxx> wrote in message news:200908222152.55846.webmaster@xxxxxxxxxxxxxxxxx > > What it looks like to me is that something is causing $foo to be a > > string before the '$foo[] = "bar";' line is encountered.
