Re: What is "->" mean in php?

If you have any Object Oriented Programming experience, then you may not had asked this. Its a operator to access methods, and variables inside a instance of a class , in which the variable before "->" is the instance of the class and the latter is a method or variable of that class. This is what I know, if you have any explanatory docs, pls let me know.
