Name
previous_object() - returns the object(s) that called the current function
Synopsis
object previous_object( void );
mixed previous_object( int x );
Description
Returns an object pointer to the object, if any, that called current function. Note that local function calls do not set previous_object() to the current object, but leave it unchanged. If passed a positive integer, it goes back the given number of previous objects in the calling chain. previous_object(0) is the same as previous_object(), previous_object(1) is the previous object's previous_object(), etc. previous_object(-1) returns an array containing all of the previous objects.
