'data' php question

[peptobismol]

I'm messing around with a skin of a wiki and I ran into this line

foreach ($this->data['sidebar'] as $bar => $cont) {

so what's data? it's not a variable but it's formed like an array

thanks

It IS a variable. A variable of the object you are looking at. You might not see the variable if there is a __get() function defined, but it IS a variable.
