In an Object Oriented Programming (OOP) language like Java, it is called a method. In a procedural language (like QBASIC or PHP) it is called a function. They are the same thing. Most people use them interchangeably. -DJ Craig A function returns a value and method does not return a value. A function that doesn't return a value is called (procedure / subroutine)

In specific Regards to PHP; The difference between a Method and a Function is that a Method is tied to a specific class. Hope this helps. -------------------------------------------------------------------------------------------------------- function can return value where as method can't that is the main difference between function and method --------------------------------------------------------------------------------------------------- Actually you are describing the difference between a function and a procedure. Function returns a value, procedure does not unless you are using c#, then everything is a function. In c# a function, to paraphrase the first answer, does and thing and does it well. A method contains functions. The most important method is the Main method. All functionality of a program must be referenced in the Main method because when you run a program, it starts at the beginning of the Main method, and stops wehn it hits end of the Main method.
